318 and which cam?

That cam should be good for atleast 6,000, I would work on tuning and gears if you want more power

The eddy carb is holding it back but it can be made better or slap on a holley 750 DP and I guess we help you tune it, lol

Main reason why I'm considering swapping out cam is cause i have to tear it down again and while I'm in there I was considering the Comp XE268 477/480.

No doubt I'll need better gears down the road and yes I appreciate all your help with the tuning
