Today, dollar for dollar, is the 318 faster than the 340 ???

I just said my most expensive motor i put together in any of my classic cars was 1450, not even half of the 3k budget.
So if you didn't get the 360 and found a $400 340 + $150 sleeve you would only have $2000 or less into it. Still under $3000. Your resale would be much more higher for it as well.
