Realllyyy fun on the bottle!!! Love it!! I spray on the street with the stock 10bolts and it hooks hard in 2nd gear, kinda hard for the diff LOL I just never spray out the hole(no traction anyway) or no clutch dump and the diff last 6-10 months, depends how much street action it sees.

The heads will be checked to be sure they works well with the combo. New Era does his own CNC machining in the shop so it will be easy to port/fix the heads.

I'm sure there are may variations of that cam that use that family of lobes that are around the same size at .50, but are very different cams based on your setup and heads. I know the lift on my cam was very high; to complement the great flow of the AFR heads. Man, I wish I would have never traded that setup for those wheels.

i'd say the same. if the heads aren't built up to the cam specs (6XX intake and 6XX exhaust) your missing out on power

The lift is indeed kinda of high 629/629. My 243s are heavily CNC ported, I'm confident it will perform very good
