The torque curve in most 396 LT1 dyno's I've seen cross 400 RWTQ at 3200-3500 RPM's and drop below 400 at around 5000 RPM's.
The dyno from the magazine article with the AFR 195CC heads show the torque strong till 6200RPM's. The 350 in this tread also shows strong torque to 6000 RPM's.
With my 396, you are looking at aother 50LBS of torque if it is still at 400 at 6000 RPM's.
We should know next month since I just ordered the AFR 195CC Competition heads this week.

A 300 CFM street head (small runner) is extremely rare and hard to come by.....in fact I have never seen another 23' head come close at that finished port volume. Along with the new 235, I view both as one of my more notable design achievements in my eight year tenure with this company. Im proud of all of them of course, but like your kids, there are a couple that you secretly hold a little more admiration for....
It looks like a smaller version of the new 235 btw.....
Looking forward to your results
Cheers,
Tony

I hope you upgraded the drivetrain, because with that kind of power your half-shafts are not going to get you down the track.... and if they do, you wont have a clutch. lol, I think this thread proves that C4's are a force to be reckoned with.....

I will give an assist here since I was in on one of the responses about stock C6 Z dyno numbers.
The OP posted his hp/tq dyno numbers and claimed that a C6Z had been on the dyno previously and made 450rwhp. We agreed that this was in line based on what we have seen stock C6 Z dyno numbers do on dyno ject +/- 5-10 rwhp.
So if the stock C6Z got off the rollers and the OP put his car on...then the dyno numbers he reported should be a pretty good read...assuming the same parameters of the dyno.
