1985 vette with a 383. Put down 406rwhp. Not bad at all if I say so myself. I was expecting 350-375

I'm not denying what the dyno read. But, that seems unusually high for your engine combination.

The ultimate dyno is the mph at the dragstrip - when are you going to run it? I'll be disappointed if you don't have any dragstrip plans.

With ~ 370 rwhp mine has a best of 114 mph - yours should trap ~ 117 mph or better.

honestly I dont know if i ever will. This car is setup for autox and thats what I plan to do.

The motor will not be in the car come next summer to lighten up the car for the twisties.

Never know tho. May buy some more rims and a set of MT DR
only time will tell
