To do a 331 out of a 302 do you have to get the machine shop to machine the block so the rods don't hit the side of the block or is there clearance?

not if you use the 5.315 rods, 5.4 is close

usually 347's have to

I hear a rumor that you can use a 351 crank on a 302 block. is that true? what would that mke the engine?

Just don't pay over $750 for a Scat 331 with upgraded pistons.

They have different main sizes. To put the 351 crank in the 302 block, it would take some work.

so you're a dealer of the scat kit? I'll keep you in mind in a month or so and let you know what i decide.
