I wonder if the combination of my light flywheel and the cams will make it a strong runner, but take a whole lot of smoothness out.

I'm sure my 91 is quicker than my 95. The cams do not make it any less tractable in any manner. The engine runs very smooth, even with the AC on in stop and go traffic. Pete really knows what he's doing with grinding and timing. I have a light weight flywheel as well.

The sound of the cams and B&B exhuast is pure music.

The 95 just seems like any other Corvette, after driving the ported, cammed 91.

Any idea of hp on the ported, cammed 91?

500-520 or so. With 4:10's, it's a beast!! Thinking of selling it and modding the 95.

Shouldn't we do 500 or so without cams?

Maybe Pete or Marc will chime in??? I've never dyno'd my car. I have intake and exhaust grinds.

Marc Haibeck offers a 510hp package without cams. In sure Pete can do it as well but I know of 4 or 5 members with that package

My car has intake cams and I absolutely love them! Wish I did the exhaust cams while I was there....

Love the sound and power the cams offer.

Sooo David, you're around 522 hp. 510 by Marc's numbers, that means 12 hp by cams???

LGAFF · 10-02-2013

might be more than that, alot of it depends on the dyno and conditions, including engine condition...some run without an aircleaner thats worth a few HP....how hot engine was,etc

Cams should get you 20-25rwhp

Blue Flame Restorations · 10-02-2013

Then I should be right about 525hp. I have headers and my exhaust is non existent.

LGAFF · 10-02-2013

You can get any # you want on the dyno if you diddle with the system....thats why its hard to compare on dyno to the next

You might have more Brett....
