well the 283 crank in the 350 block is gonna be an "issue", im sure someplace makes the bearing spacer for small journal(283) to medium journal(350), but i dont recall seeing them. the easier way would be to use a small journal 327 block with the 283 crank, however in a street car i would highly recomend going the rollerized 350 route, after all rpms are cool, but more inches the better.

i know a guy here in town with a 302 ls1,its damn bad.

Isn't a destroked 302 just a 30 over 283? 67-68 302's were 283 cranks in 327 blocks with good rods and pistons, double hump 202/160 valves,etc. and awicked intake,Holley?

To make a 302 from a 283 block, the 283 would need to be bored 0.125" over, to get the 4.00" bore. Only the early blocks allow this much of a bore.

[I am looking at a 302 article right in front of me and it makes 501 hp at 8000 rpm. The camshaft referenced is a Lunati RRA-675/669 w/282 deg @ .050. But the heads they used suck (old 2.02 slant plug "Turbo" heads) The engine used an Edelbrock Super Victor type intake. The crank used was a factory 302. The rods were factory "service" rods. The only bottom end change was a switch to lighter aftermarket pistons.]
@speedster-

was there anything done to the heads or were they bone stock? is there anyway i can access this article?
