1st dyno.....huge smile
at the wheel 320 horse and 405 ft lbs of tq and that is with the stock tune. i am sooooooo happy. it took about 7 weeks but it will be in my garage on thursday. i can't wait. some info..... auto
383 stroker with forged internal (will have nos in about 2 weeks)10.4to1
superram
1 3/4 headers, no cat, magnaflow catback
afr195 heads, hyd rollercam 224/232 @.050 114 lsa, 1.6rr
y next step will be different gears from 2.59 but i think i will wait and play with the car for awhile.
i was thinking i will get about 30hp and 20tq with a good tune is that about the right numbers?

Impressive #'s. 
It depends how far off your tune is, to how much hp you'll pick up on a dyno tune. With your combination, I'll say you'll end up with around 340 rwhp. But, with over 400 rwtq, that thing must be a monster.

i don't have any sheets on it. he just called me. he said it was not getting enough gas after about 4000rpm and he needs to get the tune off of the net before he dyno's again. i hope my hp climbs i am happy with the tq. the engine builder said i should see 450hp/500tq at the crank i hope he is right.

My new 85 pump couldn't keep up pressure and I only have a 350. I put in the Racetronix fuel pump kit and pressure is steady at all rpm's. Just a thought.
