Everyone please post torque @ 3000-4000 It seems to me that many people talk about some of these smaller port volume heads making killer torque down low compared to a large runner head, but I just haven't seen it. Please post #'s in this manner

This is with heavy drivetrain. (Heavier than stock driveshaft, 65lb wheels/tires, 12 bolt/4.10s) My numbers might have been better had I not had a busted clutch during this pass.....
3000- 310rwtq
3500- 357rwtq
4000- 370rwtq
Peak torque 405rwtq @ 5500rpms.
Stock heads, CC 212/218 .522/.529, SLP LTs. #'s are Dynojet SAE, complete mods and peak #s in sig.

i like the way u added taht 2500rpm 310tq
... hope my f14 does the same, futral kicks ***..im having them port my 241 casting heads im sending them... im going to ask him to add more power everywhere including down low, im sure he can do it lol
isnt this thread suppossed to be a corrilation between the tq at those specific rpms and the port volumes of the heads? 
as is this thread is just another "dyno" thread.
before the wide use of the AFR 205 heads the only note worthy setups i recall are the TEA 2.5 ls6 and custom FMS cam, a few LGM combo's using ls6 heads and x2/x3 cams. i must say, that TEA/FMS combo had the most beautiful tq curve i'd ever seen; 350rwtq @ ~2800 and 400rwtq @ 3500
.
do you remember the port volumes on those heads brent, i seem to remember them around 231cc.
