An engine builder friend is suggesting either of these two cams for my application. http://www.summitracing.com/parts/SUM-K1105/ http://www.hdmaddog.com/Chevrolet-GMC/Camshafts-Lifters-Cam/SB-Chevy-327-350hp-Complete-p3678288.html Here is what I am dealing with. - Engine is a 1969 block 4 bolt main 350 - Vortec cast iron heads with a max lift of .475. Stamping #12558062 - Do not know what pistons I have. Never removed the heads but believe them to be flat top since everything else on the engine was vintage 1969 and my engine guy said dish pistons did not start showing up until the early 70's. - Block has been decked but not sure how much. Can no longer see any engine code stamping on the deck. - Will be running an edelbrock or similar up to 5000 rpm intake. - Highly tuned quadrajet. - Mallory slightly better than stock distributor. - Full length headers going to Flowmaster dual exhaust that dumps out the rear - 3.42:1 posi rear. - Stock converter. Don't want to change it out at this point. Maybe in the future Want to get as much as possible without changing anything else. Goal is good street manners but with a few balls. Thanks for the help guys!
