WAG- mid-13's @ 100-102 MPH w/320-330 HP at the flywheel.

Don't know where the guy w/the dyno simulator has been lately- I'd like to have read his take on R/A that was going on until recently.

Where you at, TI?

I have an 86 c-10swb with a 355. I havent ran it dwn the track but it'll git it.
As for as hp im right at 290hp. I had to go back to stock heads because my custom ported heads went bad so now im looking into getting vortecs

Like I said- a WAG! lol

The Comp deal sounds a little optimistic to me. But I'm putting together a Vortec head engine in the near future, so I hope you're right!
