I broke away from work long enough to get some numbers today. I was hoping to make a little more horsepower but on motor alone at 86 degrees 30% humidity we pulled 360 rwhp and 370 rwtq. Time to make some changes! BTW, Here's where the dyno was done.

I would have expected maybe a few more ponies considering your heads and cam, but all in all, those are still very serious #s. I'm sure the added length in driveline compared to an Fbody or vette hurts you a little and I have also read many times that the 4.10s will lower #s slightly.
I wonder if the Flowmasters are hurting you any? Do you have cutouts? Some 3" conduit makes real good budget cutouts for about $8 a piece in materials.
Good luck with your changes and keep us posted. Those #s look good to me and nothing to be worried about.

I'm thinking about pulling the cats off and going to 3" exhaust from the headers so cut outs would be a cheap alternative for now. I'm not sure if I"ll gain very much but that's all I can do since I've just opened the intake. You're right, the 4.10's will lower the dyno numbers but help my ET. Greg, you might still take me at the track, dyno numbers don't mean everything there. LOL
