I was thinking about swapping the 3.86 crank from the 478 V6 into my 305 V6... Then you'd have a 4.25 bore by 3.86 stroke netting you 329 V6.. bump up the compression and shazzam you have the same power as the bigger V6s from a smaller higher compression unit probably saving a bit of front end tonnage too😎

I do love them all 305/351/379/401/432/478 plus the 637 V8, and 702 V12🤩

Always thinking of ways to do it differently
