Have a chance to pick up the short block detailed below. What heads and cam would you suggest? For now it would mated to a powerglide with 4 speed plans in the future. 1965 327 small main block, bored .080 over, torque plate honed, square decked, and ***embled to short block. The crank is a factory forged steel 350, cut down .150" on the mains and .100" on the rods to pre 1967 sbc standard journal specs. I also added .020" of stroke, just to make it a true 3.5" stroke engine and get the pistons closer to top deck for quench without having to cut a bunch off of the block. The rods are 327 "heavy duty" forgings, and slightly thicker than the typical 283/327 rods (These took a while to find). They have been resized with ARP bolts. Pistons are cast silvolite 350 flat tops, and sealed with Hastings rings. The engine is balanced, ***embled, and ready for cam and head selection
Not questioning your words of "old school" but my work up is this is a 366". Old school 327" was a 331" needing a 30-30 Duntov and a set of 1.94's with a 64cc camber. Sounds like you need a more cc's to keep the comp ratio to run on the street if that what your looking for. Your gaining 1/4" stroke over stock and .020" over a stock 350" stroke and a milder cam can work well for torque. Good luck.
Your question has got to be one of the most often covered sbc topics on the HAMB. I have my own thoughts and so do 1000 others, so I'll bow out this time. One thing is your 327's overbore of .080, that's a BUNCH of metal removal. This is an old discussion on that subject from the HAMB. Pay attention especially to post #10.

I know where there is a "complete" 58-62 Corvette 283 4v for 600.00 . Not running but as complete as it was in 64 !
