I am more than likely going to make 540 EFI's out of mine. The Whipple also looks good now. 725HP will not be friendly on the drives.

It has the B Max drives on it ,I talked to Dean at the Bravo Shop and I am sending them back to get cked out and one is not shifting to good and he is going to fix that. So I should be ready to go??I do think the CR is down because of the Blower pistons so that should be the cause of the mph difference from the factory test report. we'll see??

The lifters look ok ,looks to have some water stains from sitting up . I have not felt the rollers yet ,but I plane on replacing them anyway, good insurance .these only had 180 hours on them , I am real easy on parts early in the day,until
Winter has;nt even started here , the last 2 Sundays we have been going drag racing ,but it looks like rain this weekend
The car is picking up ,fixing to break into the 8'sArticfriends before OSO and computers I stayed in the garage playing . I guess thats my down fall
iamfaster you might have to wait, don't get DT's
Open 72 go back to work and quite looking in the background
fountain_333 These heads have a LITTLE port work done to them , I am going to have them flowed just to see the #s,This may give you an idea on what the do.
Lou I will get you some pictures of that oil change system I made.

Re: Hustler 500efi engine tear down & Build Up
Ck out the odd ball cam bolt 
no lock tite
Does this timing chain look like a stock 500efi??
It had some slack so I will prob put a cloyds hex-a-just in it.
The KE oil thermostat kit, remote adapter with steel RUSTING fittings . I will change them out.

Re: Hustler 500efi engine tear down & Build Up
Rod bearing in #1 motor , its 3 different name brands Michigan 77,Clevite cp743p,FM-7200ch.
The 77 had a large chamfer [for a stock crank.WHY?]
I understand sometimes you mix up bearings to get the right clearance, But 3 different ones I have bought the under or over size bearing and used just half of it to come up the that special clearance ,But
Look at the 3rd pick on the chamfer , lot of rod not supported

Laz here is the pick on the balancing holes , small drill bit. The # 2 motor the crank has regular size holes on it .On the pistons On both motors there is no balancing marks in them??
What you think??
I figure I will get it rebalanced just for the hell of it . to make sure!!

Re: Hustler 500efi engine tear down & Build Up
One thing about motor #1 is there was not much trash in the bearings,so somebody did a good job of cleaning it.
Not on motor # 2 it had some trash in the bearings at least they where the same name brand.the trash did look normal like most motors I have tore down.
The rear main shows a little out of round . looks like where the oil pump bolt area is.Center of top cap
The crank will definitely need to be polished on this one.
I mic every thing see if there ok

Re: Hustler 500efi engine tear down & Build Up
One thing I thought was weird was the scuffing on the piston skirts. they where on the same side on the piston and just on 1 3 5 7. What do yall think??
I cked the piston top ring gap, showed .032 I sure it has worn some.
t cked the ring land it .350 down just like the nitrous pistions
And guess what . the # 2 Motor had regular rings in it, so the other had gap less. There was no RPM difference in the motors at any speed , go figure

Motor # 2 same fitting as on the other motor on the header broke ,thats weird??
Cam plug rusting, might have been a problem later on. I will paint the rear on the block on the way back up
just a few rings

Re: Hustler 500efi engine tear down & Build Up
Felpro 1211 gasket , looks to be too big and pushed down on the top, not good.Almost looks like they over torqued it. or the heads and block have been cut too much and pinched it?
or the rust from the top got it??
the # 1 motor had merc intake gaskets
pick 3 this pisses me off they want paint this little area so it want rust. goes for the same on the front of the block and around the oil pan

Re: Hustler 500efi engine tear down & Build Up
Rob--Pictures are just great. Lots of folks will be comparing your pics to what they have. When you started, you probably wondered if this was worth the time/money. Now that you got into it and found a few surprises I'll bet you're glad you did it. When you're done, it'll be RIGHT and FASTER! Lou

As for the hatch bolts, I remember the previous owner of my Slingshot complaining that they always loosened up. I thought he said he changed them to Stainless which may keep them from galling. Keep the pictures coming-great stuff! Lou
now if there was a good way the do the oil filter mess with it up side down
it would not make a mess, this kit was real easy to make ,prob about 100.00 with out the expensive hose but i wanted it to match when i was using it

Re: Hustler 500efi engine tear down & Build Up
Rob--Thanks for the pics of your oil change setup, it definitely is something to think about. I change engine oil every 10-12 hours or if I smell gas on the dipstick after a lot of idling. As for your oil pumps, the groove on the inside of the housing looks like a defect. The wear pattern half way down the main gear is something I've seen before. I don't recall seeing that chattering pattern on any of the BBC pumps I've had apart. As for blueprinting the pump, I've never seen much opportunity there. Maybe a little deburring. Never saw the need to deal with any spacing issues between the end of the gears and the housing surface the end cap bolts to. What I and others on this site are sensitive to is that if you weld the pickup on, you've got to TIG weld just a tack or two. Any significant heat will cause the gears to bind in the pump housing. It's a little before your time, but folks use to 'balance' the hydraulic loads in the pump by milling grooves in the housing/cap. As I said, Other than carefully tack welding the pickup on, not much opportunity with the oil pumps. Just my opinion. Lou

Re: Hustler 500efi engine tear down & Build Up
Rob thanks for all the pictures and posting your project for all to see. I also have the KE oil pan and pickup that you showed and have been down this road before. The Moroso pump that you are talking about ordering will not work with the KE pickup, because the plate on the bottom of the Moroso pump is too thick. We had 2 motors going together at the same time and both with that pan and had to send pictures to Kepp to prove what was going on. We ended up buying the pump that Keith Eickart uses which was a Melling. I can post the pictures tomorrow that shows what I am talking about.

Let me know ,I have not ordered them yet.I guess I can get the 77 pump and clean it up
Moroso has 2 for the bbc
22162 blueprinted at 97.93
22160 race at 67.97
I ran the 22160 on my blower motor for the Scarab with a gill pan
Lou I know all the BS little stuff a lot of people say is a wast of time but it cant hurt
Linster I just set the top part on back wards and it fit. I thought it would be funny to see if any body caught it

Re: Hustler 500efi engine tear down & Build Up
Mark is you bypass blocked off. it was like this when I tore it down . one was even loose I know on all the drag race stuff I have done I plugged the bypass also Making all the oil go thru the filter. How is your done and is the part of the Keith's oil pan package ???
anybody else got and suggestions on this??
I remember a tread on this awhile back but it was stock 454-502 stuff, difference on the pressure of the bypass.
I prefer to block it off so the oil goes thru the oil filter . because i know there will never be a restriction with the oil filter clogging up
I willing to listen to all sugestions.
Thanks
Rob

Re: Hustler 500efi engine tear down & Build Up
GM makes a high pressure bypass assembly, but I prefer to drill and tap for a pipe plug for full flow through the filter. Make sure the top of the pipe plug is below the surface that the oil filter adapter sits on for a good seal. You might want to consider the Eagle rotating assembly with the 4 1/4" stroke crank for more cubes. Good luck and please keep up the pics and posts.

Re: Hustler 500efi engine tear down & Build Up
Rob:
You can leave the center bypass valve out since all it does is divert oil to the GM oil cooler fittings in the block. Since you have an oil cooler plumbed to your remote filter you don't need this valve. The other bypass that you have plugged can be fitted with the 30 psi valve, not the 11 psi valve that is installed on the assembly line and which was left in some marine engines when the Gen V/VI first appeared. The 11 psi valve will open due to the extra restriction of the remote oil filter and cooler plumbing. The result is the oil is neither filtered or cleaned at high RPM. the plug works, but I would rather have the 30 psi valve because dirty oil is better than no oil. Just a choice you have to make.
Keep up the good work with the photos.

Re: Hustler 500efi engine tear down & Build Up
Rob Mark and i are brothers the two motors he is talking about is mine and his we both run the same oil pan and the pump you are talking abut set the pickup almost 1 inch off the bottom of the pan we called Kepp and the gave us the pt nb for the pump they ran i will look for it tomorow . also we do block off the bypass so all oil run through the filter.i was wonderong where did you get your boat and how long have you had it

Re: Hustler 500efi engine tear down & Build Up
This pick shows the Keith E oil cooler remote adapter .it looks like one plug fit tight the other cam loose.Tom it did not have the center valve, As far as the dirty oil /no oil/ I have never not missed a oil change and it has the fram/Peterson oil filter system and a larger oil cooler on it
I bought the boat in April 2002 with 46 hours on it ,from Jim bresnick[sp]?So it has had 2 different people in the motors before i got itIt had the old style Whipples on it and they had trouble with them and took them off and supposedly put the motors back stock inside,Then sold me the boat, with out the whipplesSo a lot of stuff on the out side was over kill for a stock 500efi, but i knew I would be going into them anyway one day and probably supercharging them , I am familiar with the roots style blowers and I wish they would fit with a innercooler under the hatch , the the whipples with the efi system seem to be a reliable package . Also Mark at Precision Marine is stepping up the the plate on the ecm,s and he want to Dyno them , With Precision's and yall's help I think this is going to be a good motor package
I am glad I am going in to it know , I guess I have been lucky , head gasket leaking and the intake gasket leaking . the motors have been running pretty good for 3 summers.
pick 1 oil adapter
2 oil filter
3 oil cooler
I will report back on the machine shop found on the heads,blocks, rods etc Monday

Re: Hustler 500efi engine tear down & Build Up
Rob,
If you are changing the oil pump, buy the Mellon 10777, Jeggs now sells it. Install the high pressure spring that is sent with it. Thats a very nice pump and holds good pressure. They also make a 10770 which is for a brazed pickup.
On the bypass valve, listen to tomcat. GM makes a 30PSI part # 25161284. I replace them every tear down. That are only about $3.
Don't forget that little O-Ring you are pointing to.

would there be a disadvantage in just plugging the bypass hole ??
Thanks
