Re: Dyno Results-comments welcome (drives61)
Cheating???? Factory Appearing. Not pure stock. Most of the cars there are running extra cubes. What fun are rev's without power??? A stock 72 LT1 runs low-mid 14's on it's best day blue printed or not. My car was low 13's its first time out with no tuning and should be in the 12's after the dyno and h-pipe. I tried for it yesterday, but unfortunately blew the rear on the first pass. I was enjoying myself up to that point.
The engine was blue-printed when built, balanced, cam degreed, etc. I'd rather run 12's and shift at 5,000 then shift at 7,000 and run 14's. I also don't have to adjust the valves constantly without the solid cam.
My brother in law ported the heads. He's not a pro, but is damn good (also, he works for free).
I'm not a ton off of what I thought I'd have (I expected 300-325 rwhp), but it just came in lower than I thought. I think if I could get the other 700 or so RPM it would be there. I've also got a much fatter torque curve than I expected.

Have the intake and exhaust manifolds ported or Extrude-honed for extra flow.
I would not go with a single plane, but something like the Performer RPM would work, you could always paint it Chevy Orange for a stock look ;)
My 383 makes peak power at 6700...

randy
pardon me. i thought stock meant 350 +.030-.060
if 383 is stated on your entry blank, then it is not cheating.
As stingray racing pointed out, it needs a solid cam to rev.
If once a year adjustments are too much effort for you, i have no problem with that. :cool:
