I was wondering about running this in:
92 Z
383
9.5 to 1
Miniram
AFR 195 eliminator
Procharger 10-12 psi
6 speed
4.10 gear
6500 max RPM
Street/Strip
A/C P/S P/B
Looking for 500-600 RWHP

This is a TPIS ZZ9X cam.
I've been told that its too much of a split between the intake and exhaust for the AFR heads. I was told that its more for a stock head that needs the exhaust bias because of the poor stock port.

How do you guys think it would run with the AFR's?

Any suggestions for a cam?

I'd like to run the lift around .600 as thats where the AFR's top out.
I'd like to keep the LSA around 114-116 for a decent idle and low overlap.

 

I think its abit much for duration split and abit too wide LSA. I think all you really need is 10-12 deg split. 114 LSA would be fine. Duration wise you are fine with 224 on the intake. Really streetable and tuneable.

You will be near 600whp with right cam on 12 psi. Dont necessarily need .600 lift with boost to make that power but its nice. Something like a 224-234 on a 114 and .575-ish lift would be awesome I think. Comp makes a similar grind its 224-236 i think. Works well.

That ZZ9X would work ok tho and probably make your power. It would help on higher boost and higher rpms to evacuate cylinders. All that pressurized air has to come out and more duration is nice.


FWIW I ran a 230/245 cam on a set of AFR eliminators for my n/a 383 and a 150 shot. On motor that car was STRONG. Cam certainly wasnt the typical recommended type for those heads but it really did work and had a unique sound.
