67 Cuda: disappointing dyno numbers, need some advice!

He has a DC 268 cam- about the same seat to seat as a 275 comp or 280 crane
do the compression test as we are all just stroking ourselves
IMHO forget the roller rockers and new cam till you get results
If cam is new will Hughes swap out with different cam if needed? no reason to put new cam in and make it "used" just for curiosity
Agree with YR if you do get 1.6 rockers and B3 kit and need a different cam go solid millions of 273's out there and they work better and little maintenance
Whats the bottom line on the manifold not 50 HP methinks
meanwhile look into the B3 kit so you know what you are getting into Shafts, pushrods lifters etc
I do not like roller cams with rollers on the shafts- It takes heat treated (not induction hardened) shafts do do that
the rockers are not going to make 50 hp difference either
good choice on the headers- so no big split on the exhaust duration- opens exhaust early and hurts power and mileage and also makes more heat in the ex
