Supercharger cam
I am going to be adding a supercharger to my 383 once I save enough cash. In the mean time I plan to rebuild the motor with less compression ratio and I want to run a blower cam. I have not yet called any of the cam makers tech lines. I want the guys out there running supercharged TPIs to share some of their cam info with me.
Now I am running 11:1 compression with a TPIS ZZ9 cam with AFR 190 heads. I want more cam now with the zz9 so I can only imagine with forced induction. I will keep the heads, port them some and I may switch to a miniram setup instead of the TPI, but that will depend on money when the time comes. I will aim for about 8.5-9.0 compression ratio after the rebuild.
What are proven blower cams being used?
Anyone use the Nitrous cams with good results in blown applications?
Thanks in advance.

Nitrous and blowers have similar requirements but not the same. Both like a cam biased towards the exhaust to get the spent gasses out and many have used the Nitrous HP series of cams in blower applications with success.
I'd call every cam company you can reach and get their recommendations. Look for similarities in their suggestions. Make your choice after you have considered more than just one or two alternatives.

I do plan on calling Comp, Crane, and Lunati. I am curious though what anyone running a blown TPI is using camshaft wise.
Thanks for your reply.

I know the LT1 guys at camaroz28.com have had good luck with these two cams.
63-218/230-114 Comp Cams "Extreme" LT1 Camshaft, 218 / 230, .495 / .510 114 LSA, Agressive camshaft for street/strip blower applications. Computer tuning required.
63-224/236-114 Comp Cams "Extreme" LT1 Camshaft, 224 / 236, .502 / .520 114 LSA, Very aggressive camshaft for street/strip blower applications. Heads, Exhaust, Stall or M6, Computer tuning required
So far I'm leaning towards the first one myself. Go to thunderracing and pick the 93-97 LT1 camaro and you'll see them there.
