Any updates?

still outta work so doctor wont let me do much but I did get the gimble housing all done completely rebuilt it and painted it. got it mounted on yesterday along with motor mounts. this stuff is so time consuming spent 3 hours wire wheeling bolts and motormounts but its coming. waiting on harmonic balancer and head bolts so hopefully motor will go in not this weekend but next.

Looks great man. You did a great job painting every thing. You paint for a living or just for fun?

thanks no I didn't paint it my room mate did. I gave him 2 months free rent which is like 600 bucks and 500 in paint & clear

Haha hey whatever works right. He did a great job.

solid white looks freaking great... update?

Found a smoking deal on a heat exchanger but I'm not sure if it's big enough. He said it came off a 3.7 but I'm thinking he meant 5.7 I want to atleast chill the block and possibly manifolds if I can. What yall think

That is a Heat Exchanger from a 3.7 liter closed cooling system motor.

got some parts and modivation

the factory alt/ pwrstr is bulky and ugly so I think im gonna get rid of it and make my own.
ground down the valve covers where the coil packs used to mount filled the in and cleaned them up some. I think im gonna make some brackets to hide them behind the heads.

looks damn good man. mine is still in pieces at the machine shop...lol i like the looks of the valve covers.

Watch out about putting your MSD box on the manifold (I realize the manifold is designed to mount it there). The electronics are completely potted internally but heat and ultrasonic vibration are MSD killers. Even putting it on a bracket off of the engine can act like mounting it to a tuning fork and over time shake it to death. Best place for it, is high and dry on the stern where it can stay cool and have the least about of ultrasonic vibration.

Worked in the Nascar industry for 6 years.

thanks I was wondering about that. I need to find a extension harness....

manifolds came in. im planning on making my own ss semi dry risers but after seeing these in person i think it will be harder than i thought.

i was thinking 3 inch inner and 3.5 outter. the circumfernce of that exhaust oval is around 10 1/4 and 3 inch pipe circumfernce is 9 1/2 so that gets me close if i massage the end of the pipe into this oval shape

the water jackets are my second problem. im thinking when i give the guy the drawing to burn the mounting flange, make it dry joint and just drill 3/4 NPT hole in the center of the front water passage so i can then just have a jumper hose, and weld a bung on the ss pipe. if any one has ever done this before please tell me im not crazy.......

made coil brackets today out of some aluminum. not the best looking but im ready to get this thing in the water!

Wow, that's pretty sweet setup.

did you get motor mount adaptors?

yea i just bought some off summit. i got the motor in and they work. i havent lined it up yet but it looks like it will work.


got bell housing on. actually had to trim it a little coat it was hitting the bolts on rear cover. i wish i had a bridgeport machine :poopoo: big drill bit took care of it nicely.

the flex plate works to. bought a flywheel from rockauto for like 80 bucks. 2002 5.3L 1500. only thing thats different is the bolts there metric.

hmm interesting about your bolts hitting. maybe there are slight changes in differnt castings of the bellhousing. thats a nice way to set your coils up. my engine should be home very soon, so I'll get some shots of the set up alex built for these engines. did you keep your factory intake? if you ever want to run efi I can tell you get the schematics from the dealership. I found a ton of them online but some of them are slightly different. I'll have to post my dyno results once i get that done. I can't wait to see your boat finished up man. you pick out a color scheme for your boat? or are you staying all white?

Your getting there! Instead of drilling on the bell housing, I put regular hex bolts in the cover and had plenty clearance. I just built a 6.0 for my checkmate. First start yesterday. It's a 403 stroker. The 5.3 started knocking a few weeks ago.

Got the motor in.

Congratulations!!!! I am doing the Same project as you only with a sbc into a 21' Excel. Paniting bilge this weekend... all white! speaking of all white, what happened to ur pretty bilge??? :0

Sweet! We need to compare top speed numbers when done to see if this LS is worth the extra money and head ace haha. Yea the bilge cleans up my garage isnt finished yet so unfortunately the boat sits out side. :mad:

http://i47.photobucket.com/albums/f1...0809141239.jpg

Looks dam good man. My motors finally done just need to go pick it up from the machine shop.

Any one wanna buy my manifolds? I'm just gonna get the headers.

got the headers from lightning. wow these things are nice fit good to
there monsters. almost look to big for the motor lol

http://i47.photobucket.com/albums/f1...318150_HDR.jpg

Hey did you order those direct from lightning? Those look killer man. I'm not sure if I want black or silver coating on mine.

Yea straight from them. Yea there pretty sweet can't wait to hear what they sound like

Hey I know this is an older thread but I'm about to buy a 21' scarab and painting it. I have some questions about how you prepped it if you could text me. 859 380 0240. Thanks!

Just discovered your thread ! Good job ! ... I am starting an LS swap build in my project so I am subscribing.

He mentioned above his manifolds where for sale. Wonder if still ? If so, might be a good opportunity for you.

Tried PM you but your box is full.

If you still have these manifolds I would be interested in them

PM or shoot me a txt

Thanks

I'm doing a LS in a pontoon FYI

Wow Ls in a pontoon that's cool. Yea I'm getting ready to start it up this weekend I think. I need to post some more pictures

update:

ben working on it a lot lately. got to start it up last weekend!!! :cool-smiley-026: I ended up having to pretty much pull the whole interior apart. the wall between the cabin and cock pit was only attached with two screws on the bottom. I think the build quality on these small boats aint as good as the bigger boats.

after I started it I had a few coolant leaks. take a look at the clamps I bought I though they would work better than worm gear clamps but I don't think they do. they leave a small gap right under the bolt of the clamp. im kinda worried this thing isn't gonna be reliable. I think I spent to much time making it look neat rather than function/ longevity.... after starting it the cam sounds a bit more radical than I expected. im worried about water reversion. I need to pull the exhaust off and check. .... please chime in with your opinions on any thing you see that I could improve.

got the garage up few months ago. don't know what id do wit out it now. my dad gave me these cerwin vegas he bought new in 86 I refoamed the subs they rock! :cool-smiley-011:

http://i47.photobucket.com/albums/f1..._214232601.jpg

I made this harness for the engine. FYI if any one does this and has the msd box up in the dash yr gonna have to make yr own extension harness not hard just tedious. you can get the plugs and terminals from eficonnection.com. if you do it like that it will leave you with 3 extra spots on the engine side of the harness. tach ( because that wire will come off the 16 pin plug on the msd end of the harness) and yr 5volt supply and map sensor signal cause you really don't need it. so I used one for starter solenoid, and one to excite the altenator. and then one spare. that way you got one nice clean plug for every thing on yr engine.:cool-smiley-026:

I had a friend make this water neck so plumbing to the heat exchanger was easier. I cut the old one out and pressed this one in. no leaks so far
