Hi guys trying to do a gut check on a 67 Chevelle swap thats wrapping up. Motor is a LQ4 with a Texas Speed 408 kit and the following:
BLOCK:
Texas 408 stroker kit, -3cc Pistons, 4.030 bore, 4.0 stroke, .051 gasket, -.002 deck, 11 to 1 compression
Heads:
PRC ported, polished, 69.5 cc
Cam:
COMP CAM
.623 intake .617 exhaust / 114 lobe separation
Duration @ .050 / 229 intake 236 exhaust
Lobe lift . 3670 intake .3630 exhaust
Intake:
FAST 102
Headers:
Headman 1-7/8 long tube, 3" exhaust, dual 2.5 dump
Transmission:
4l65e auto, built with a 3200 stall.
Currently seeing 463 wrhp and 450lb torque at a 6k redline pull on the dyno... Personally shooting for 500 at wheels and was wondering if anyone has had any luck achieving that number.

I would also think the numbers aren't too low considering the combo. That camshaft is pretty mild. I bet it runs good.
Seeing what it can do at the track is a good idea if able.
Can you post the dyno chart?
