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.

Seems a little low, but not THAT low...You didn't list cam duration.

I'd run it at the drag strip and see what the MPH is. That's more accurate than a dyno.

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?
