well i see tango is tryin to copy my side of the story but anyways i did some research and alot of math. i read the ccing to compression ratio from my book pg136 - pg140 (Engine Blueprinting By Rick Voegelin) and a 350 bored to 4.060 with a 3.480 stroke and .020 head gasket, 15cc dished pistons, stock .015 deck hieght, and cylinder swept volume which is 738.26cc's from TDC to BDC in your 350 which is actually a 360 now.
but what i came up with using those numbers
76cc - 8.5:1
72cc - 8.82:1
67cc - 9.26:1
64cc - 9.55:1
62cc - 9.75:1 (305 head)
58cc - 10.19:1(305 H.O head)
and the cam i found is at http://www.northernautoparts.com or call 1-800-831-0884 it was the ELGIN cam & lifters part #CL1065PK for $89.99 with recomended crane's valve springs part # 99848-16 $61.99
its identical to crane's enegizer cam. part #100052
1500 - 5500 RPM range 272dur 216@.050 110deg lob sep .454Int/.454Exh lift. Also the same as Comp Cams 268H part # CL12-210-2 which is more spendy than ELGIN and Crane.
