I have a set of ported heads on my car here are the specs,
Lift cfm Flowed @28"H20
.100-70.30
.200-136.52
.300-193.94
.400-237.90
.500-244.80
.600-248.60
.700-251.50

I don't have any exhuast #'s The motor these heads will be going on is a 383 ci LT1. Compression will be around 11.5:1 and the motor will be seeing 2-300 hp Nitrous shot. The car is a 4L60E with a 3,200 stall. I don't drive it everyday and I don't race it every weekend. I just like to play with it on the street and on the track. What cam would go good with this setup? Keep in mind the N20 will only be used a few times a year(5-8 times).

Thanks for you time and input. Sean Foster

 

thats alot of compression for such a big shot!!

 

Nitrous loves compression, I see no problem with that combo. Why not go with one of the big boys since you're making a 383, CC 306 or GM 847?

Even better, an LE3 cam.

 

He's lying it will see N20 2 to 3 times a day. He needs help he is addicted.
