Is my engine performing as it should??

The cam you have is capable of 350HP.

I did a camquest and came up with something around 370hp 420 tq which is still pretty aggressive. Those programs also assume a perfect tune. It was almost spot on with a couple of recent builds compared Dyno numbers.

1.7 rockers are a ***** to use, cause all sorts of problems. Adding lift doesn't equate to making a ton more HP. Sometimes it's negligible. On your style, desired build engine, they flat aren't needed. There are valid reasons to use 1.7 rockers, IMO, none of those are present here.

That engine could run with a 950hp on it. I wouldn't run one with your converter/gears. Some say it's crazy, but, they work. Done it more than once. The carb you are running will make it weeze up top IMO. Driveability will be good, max power won't. SB chryslers tend to love carb.

Good luck with it.
