Re: Seriously thinking about 305 upgrades

I believe the major reason these engines lack power is that the bore is too narrow to allow enough valve space for the length of the stroke. Intake and carb may help, but I don't think you'll get enough of a difference to justify the cost. Honestly, you'd probably be better off swapping in a salvaged 350 and leaving it stock.
