cam selection for Procharged 350

[DeltaT]

Big G,

I currently have a Comp Cams Xtreme Street solid roller in my 383, 230/236 on a 112lsa running 1.6 roller rockers, huge FMIC and multiport injection. I believe it's a great cam for a 3500# car with an automatic. It put down 632rwhp at 11.7# of boost and since I changed the air intake to the blower and added another idler wheel to the 8-rib setup (allowed some more belt tension) I am hitting ~12.9# of boost. The cam is done around 6250 even though I can spin the motor up to 6900 no problem.

Idle quality was important to me since the car is supposed to be a sleeper (a bit loud though). Unless you don't care about idle or have a lot lighter car or a stick shift, I wouldn't go larger than a 236/242 on a 113 with that D1SC. If you have a stick then go for the cam you mentioned - it should rock.

It is almost identical to the solid roller I specced for my new 434 smallblock with a Whipple 3.3 twinscrew blower: Comp 242/[email protected]", 115lsa. Net lift .630"I/.674"E using 1.7I/1.8E T&D shaft rockers. Will go into the same car with the 4L80E and a new, 5-disk lockup Vigilante converter.

Thanks for the response, DeltaT. The 'Vette weighs in at about 3,200 lbs. and is a manual 5 speed. Running FAST fuel injection with Edelbrocks Vic. Jr. EFI intake. I need to find my missing HP, only 555 rwhp. My a/f ratio may still be too rich at 11.0-11.8 at boost. What heads do you run and what is your c/r? Do you have a plot of your dyno run? Thanks, Gary
