Did you make those spray bars? They spray down on the cam? That hatch bracket was a good idea.

They are the KE Spray Bars. They have 16 pin holes in the bottom of the bar that sprays a constant stream of oil on each of the lifters rollers.

The Machine Shop is machining the bolt holes and taping into the oil galley for an oil feed. Pretty simple deal to install.

Mark great job on the blowers! What did you use to polish them? Wherdid you get the parts?

Jamie, I used a 6 or 7" buffing pad that attaches to a drill. I bought it from ACE. Here is a picture. I dry sanded the blowers with 2000 grit sandpaper (Got it from Finish Master) then hit it 3 times with mothers and the buffer, On the third round it looked like a mirror!!

I bought all the blower parts from The Blower Shop. The bolts were custom ordered from ARP (Honestly they look like ARP Flywheel bolts with a little more thread 1/2 x 20... you could probably run a thread die down some flywheel bolts and save some $$).

The Star washers came from Dan Neumann, he gets $20 a washer for them.

your pm box is full :D


is there anything special you have to do when putting the new teflon strips in? I have a pair of BM 250's i was thinking of going through and that is the only thing i am un familiar with. I have all new bearings and seals, just need a few more things.

Hey Dave, Pm is fixed!! My memebership was up yesterday! On the strips you have shave the teflon down. It's best to turn the rotor on a lathe while doing it. But

You can shave them by hand with a long file.... Measure how tall your teflon is now (in the rotor) that will be real close to the spec your going to use. your looking for .005" clearance with the case.

Went to the machine shop last night to get an update.....

My engines are at Fast Forward Marine/Race Engines and Joe Irwin there is awesome!!

Anyways I took the engines to Joe to double check Nortech's (Daryl Hameetman) machine work becasue I was not liking the readings I was getting with my gauges.... Joe had to machine the spray bar and clean the blocks anyways....

Long story short we have to take the blocks to the next bore size.... I love spending money twice!! Plus I need a new crank... :angry-smiley-038:

Hopefully the line hone job Daryl did is ok :lolhit:

Dave you might want to check out Fowler Race engines he's in ohio he rebuilds most of the top fuel guy blowers, he rebuilt a few for me hard anodized and teflon striped them when i was racing alky dragster he knows blowers.....

Got an update from the Joe Irwin at Fast Forward Marine/Race Engines today https://www.facebook.com/FastForwardRaceEngines

Machine work should be done at the end of the month!! We are on track to meet my end of April deadline!!

Budget is getting extremely tight though :lolhit: imagine that :angry-smiley-038:

Joe is going to tune the engines in the boat old school style! Dyno is not going to be in the budget.... I will gauge the HP by the mph in the boat; it ran a best ever 92mph with props spinning in. Props are spinning out now and best I have seen in flat lake water is 85 mph.
