1968 C25 307 to 350 Swap Advice

[streetstar]

I'd get the crate motor --

I have an odd affinity for the 307 too --- its a nice engine for its intended purpose, but not worth throwing a lot of money at ----

Plus the bore size is not conducive to taking out to 4" (size needed for a 350, ) - and the stroke is too short.

People have told me they have successfully taken the bore to 4" though and it resulted in a large journal 327, which some think is kind of cool
