Oops, definitely meant to say 100+ rwhp less than it should be lol. Completely unlucky

I have a 3.33" and am running 11lbs at 6200. I am at 400 rwhp with cms stage one cams lt's and the blower so you get bigger blower cams and a smaller pulley and you wont have a problem. I agree with the guys saying RR 2.97

I made 440 at 6300 rpms through my Auto

stock PI motor with Eddy victor Jr on top of it and a vortech Si

Im running a 3.15 pulley through a FMIC.

Prolly made 12-13 psi at the most at peak

I would recommend the 8 rib setup strongly.

I got all my 8 rib pulleys for less than 200 bucks.


With the cams I would think you could make 450 rwhp if you can push 15 psi into it.

If you throw the Edelbrock intake on top of it you will make a good bit more power.

My buddy just went from 556 to 650 rwhp swapping from the PI intake to a Edelbrock intake on his car with trickflow heads and cams

the only thing i have against the 8 rib is that i'll have to find a 3bolt timing cover/tensioner. also i'd love to do the eddy intake, but then i'd want to convert to a return style fuel system so i wouldn't have to get a bunch of adapters for my frps and stuff. do you have the stock returnless or go return style justin?

You could try a RR pulley...probably would be minimal belt slip with that and a 2.95 pulley.

96/97 has Return style

so to answer your question I do have the stock system but it is Return style.

And its actually cheaper to keep the returnless style system man.

All you would need is a 50 dollar adapter for the fuel pressure sensor and it would require less fittings and adapter.

My regulator alone was close to 200 dollars with the gauge.

Very true...I looked into upgrading to braided steel lines and changing my fuel system and it would be over 1k for the lines and fuel hat etc etc
