Have not gotten to a dyno yet. I used a 74 9.5 block, Pro comp 225 heads, Comp Cams 284ex cam, forged 22cc dish pistons (will be just a tick under 10:1 compression) Scat kit, edlebrock performer RPM, Comp cams gold series rockers, ARP bolts and studs all through the engine, . Still not settled on a final carb. Got a plain 600 holley on it from my 289 just to get it started and through the break in. Got an Eddie 750 I will slip on and try. But looking at a road race prepared holley. MSD ignition on points right now but have a new duraspark to modify and put in. Lakewood scatter shield which has a wide ratio top loader hanging on it. Final link is an N case 9 inch daytona bearing with 3.55 detriot locker.
