1966 273 2 barrel mods.
I'm not trying to step on people's toes here the OP wanted some ideas I gave him my opinion I got a 5th Ave with a comps XE262H, eddy intake and carb with headers and duals there was a write up with the similar set up with same cam on a stock 318 long block and made 282HP @ 5000 and worked pretty good until my rear end went. I was just trying to get the OP headed in the right direction. I just use Comp Cams as reference because 80% of the build up's I read use them so I know there spec's. Those seem like nice solid cam choices when I was looking for cam ideas for my 273 I couldn't find many solid cams other than race cams.
