Damn! I need to get in touch with this guy that did your tuning. I've got a set of home ported heads that I assume are 20cfm over stock. I've also got a gm847 cam. How much cfm over stock are LE1 heads?

Kryckter did the tuning, on Zach's T/A and on his own freak 417rwhp LE2 setup. He has the tricks for these setups down.
Yes it is a stock bottom end 140,000 miles and going
One of Lloyd's LE2 flow sheets(not Zach's heads)
2 136/102
.3 192/137
.4 238/164
.5 265/183
.6 271/188

Ya , Zach and Joe are on there way back from Lubbock right now, i'll have Joe or myself email it to you tonight. Joe said it was over 300rwtq from 3,000-5,500rpm's.
EDIT
I just looked at the tq curve on the graph, and its above 350rwtq from 3000-5700rpm's

Re: 400rwhp LE1 Heads with CC306 Dyno numbers
Kryckter put down 400rwhp 361rwtq on stock bottom end, then on his forged 355 he put down the 417rwhp and 381rwtq. I'm not sure if the little small block can put out any more torque on a hyd roller, unstroked, stock bottom end. But it would be nice if it did.
