Hey I'm trying to figure out how many cubes I'd have after stroking a 302 (like a 331) 2.25 I think with a small bore of 4/100th. Is there a way to figure this out?
Ok thanks for that BUT. I'm using a brand new Boss 302 block. Does that allow a bigger bore? Basically the guy working on my engine goes "well since it's a 302 boss block we can get a lot more cubes than a 331. Is he implying go with a 347? Does the boss block allow a larger bore?
The new Boss block can be bored to 4.125.(plus another .030 or so) Combine that with a 3.25" stroke and you've got a short stroke 347. Go with a 3.4 crank and you're up to about 370 cubes. Ford's new crate 331 is a 4.125 bore X 3.1 stroke crank.
