Since i know all you guys like projects, I figured I would share my current project I'm turning out for my uncle. It's a 64 CORVETTE numbers matching 327 365HP lemans racing style. This is one of the origanal factory race VETTES that GM turned out back in the day. It's a stripped down base model with no power steering, no power brakes, manual windows, only factory installed option was heat. A few years back he had me build up to be a quote "BAD B!TCH" for the street, so it had forged domed pistons which had him to about 11.5:1 compression, a COMP 292 cam, screw in studs, roller rockers, ported 461 heads with 160/2.2 valves, 1 7/8" HOOKER side pipe headers, VICTOR JR intake, 750 double pumper race carb, and an MSD ignition. It was a conservative 500HP as it was a STRONG beast. He took the car and had it restored, and now he wants to street drive it with A/C, so I'm now detuning it a bit and making it pump gas friendly as finding 104 octane leaded fuel is tough enough without mentioning the cost. So in with a set of flat top pistons to drop the comporession ratio back to about 9.7:1, put a COMP 274 cam in it to get some manifold vacuum at an idle for the A/C, going with a set of 1 5/8" HEDMAN ELITE headers, and a basic HEI tach drive distributor. Going for about 325-350HP and streetable on pump gas.
Heres a few pics I have of the engine, I'll get some pics of teh car here in the next few days once I get the engine finished and uncover the car to drop it back in. There crappy cell phone pics, but it's what I got for now. More pics will follow.
The heads with screw in studs, guideplates, and the guides were just machined to install valve seals as the early 461 heads didn't use seals and she was a smoker out the right bank sucking oil through the nurled guides.
All back together.
Bottem end all buttoned up with the stock windage tray.
Flat top pistons installed, can't see it very well but they are polished out with a buffing pad and oil(helps keep them from carboning up, and reduces hot spots for detonation).
Camshaft degreeed in and buttoned up with a roller button and lock plate installed(cam button isn't needed for a flat tappet, btu I like extra insurance. Helps also with maintaining good solid cam timing by keeping teh cam from walking during decel).
Short block all finished up.
Here you can see the cooling passages around the plugs. The engine kept overheating at an idle, turns out these coolant passages were plugged. These heads had just been hot tanked to, and were still plugged. Had to drill them out to open em back up.
