Cam
Re: Cam Sorry for the late reply. Its a comp cam custom grind that Nick Agostino recommended. His exact words where, "it will be a monter on the jug"!
I am no cam guru so I cant tell you the ins and outs...but it does perform. For comparison old motor VS the new motor, Old motor was a stock shortblock with CNC neads and a comp 218/220 .525/.532 on a 114lsa cam MAC headers and boltons. With what Nos calls 140 shot pills and the pressure at 1175 psi I used to make around 460 rwhp (na was 360 rwhp). A gain od approx 100 rwhp.
The new motor is a 383 iron block with ARE heads and the cam from the above post, Everything else was the same including the MAC headers and same 140 pills run at 1175 psi. It put down 422 rwhp NA and then 611 on the very first nitrous pull. Thats a gain of 189 rwhp from the same flow of nitrous. So the combo of cam and heads works and works well.
I know I would stand to pick up a great deal of NA hp by swapping the cam. I may do that in the future but to date I have only run once at the track NA and that was on accident. So i am looking for max HP on juice.

Re: Cam Very interesting re: the cam specs and your performance. Sure seems like that cam fits your car very well...impressive.
A related question: I have a '96 Corvette GS 'clone' with a 454, Brodix heads, 770 cfm Holley 4 bbl., 10.5:1 compression, a 400 NOS wet shot, a Jacobs Electronics Mastermind controller, and relevant to this topic, a Crane Cam hydraulic roller 214/222 with .553/.576. What are your thoughts with this cam in this car WITH and WITHOUT N20? I have been told that the "mildness" of the cam (whick limits my RPMs to about 6000) is ideal for N20 (that was the seller of the car, so who knows). Comments are appreciated. I havn't run the car or put it on a dyno, but I'm hopeful for low 10's et, and HP of 500 NA & 900 N20 (at the crank) and about 400 & 750, respectively, at the rear wheels. Does this sound like realistic goals? Thanks. FoFo.
