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

Haven't got a et or mph on the 400hp 318 I built still getting other things lined out. But I can tell you that in my 3500lb dakota with 3.92 gears and 24.5-25" tires the smaller cam motor all stock internals except cam. Was smacking the 6000rpm Rev limiter right at the end of the 1/4 in the 1/8 it was running 8.80 with sever traction problems that I never addressed. This was at 4,500' elevation. People were accusing me of having a big block. So a long box peg leg dakota piss poor 1/8 times and I was still running in the 13's in the 1/4. It dynoed at 330hp. No I don't have the dyno slip that was 10years ago

Your motor runs fine just alot of different combinations out there. That's what racing is all about
