So, I’ve had this idea rattling around my head all day, and was wondering if anyone could give some helpful/useful information regarding the subject.
Basically, the major downside of chevy’s 305 is the geometry. It’s got the stroke of a 350, yet a bore of like 3.736. Small bore+long stroke in a gas engine just doesnt make good power. I know there’s issues with the heads, but I’m just talking about the short block here. Basically, my idea is to take a 305, put a large journal 327 crank in it, bore it over as much as you can over bore a 305 (I’m not sure how far you can go, I don’t know a whole lot about the casting of a 305 block), and put domed pistons in it to take up for the shorter stroke because custom pistons are expensive. This would essentially make it closer to an over square motor, and the 327 crank is a little more suited to high rpm. Just a thought though.
Thanks
