Easiest/Cheapest way to a 4bbl 318?
These cams are going to run more like the hughes wiplash cam because of the lobe center being 108.
Hughes makes that part of the cam tighter to get that chunky sound.
These are better running in a stock engine, that has stock valve guides as far as clearance with the rocker arms.
The 264-mega cam is a real good cam for you.
Also the 280 -hl is great (but)this is a pretty good size cam (SO) at this point you need to look at your gear ratio.
This is going to be the key point to your cam selection.
What is your gear ratio??????
