It would help out alot if we knew a bit more about the setup?

Heads , Stick/auto , blower , pulley combo , rpm range desired , gears.

They all go hand in hand.

the setup is a 402 9.5:1 CR. ported L92 heads, L76 intake, 90mm throttle body, stage 4 t56, d1 blower 12 psi, 4:10 rear gear.

not sure on the rpm range.

just looking to make 800+ at the wheel with mostly the blower.

i would like to keep vary good gas mileage in the city and highway, and be vary street able.

i know this is hard to accomplish.

The blower will need to be maxxed out to provide that amount of hp. A 3.40 pulley is about needed to put impeller speed up there.

We offer a stage 2 cam for 400in motors, it is a 236/246 114 .604 / 610

With that head/Intake tame down the Cams.Use a high lift high 220's intake with 10 degree's split to the exhaust. Big Cams are crap with boosted L92 heads.

It sounds like our original blower cam is more in line with what you are looking for. We have it in this Cadillac CTS-V that has a 402 in it. Here is the dyno graph from this V.



We just installed this camshaft into a GTO that we drove 120 miles yesterday (Sunday) to the Indianapolis airport, for the owner to pick his car up and drive it back to Kansas. It was getting 21 mpg on the way to the airport.

Here is a link to this camshaft.

That is nice Bob. That is with a F1R right? How do you think a 235/245//598/608/115 cam would compare?

Something like that, possibly a hair more lift and put her on a 114.


As for clutch, if your around 800hp and beating on it, grab a spec 5 or a twin disc setup (preferably a mccloud or a spec).

Yes, i do not like it. I had one weld together and the second one was noisy as can be. There has been a large amount of people blowing through them with low amounts of hp.

We have had great results with the spec line of clutches, not so much chatterey or loud, just a firm pedal.
