jeff you should really look into the TFS 225 for a 370. i think you would see just about the same results, cause the TFS 235 are really for a minimum 4.10 bore if i am not mistaken. but with a 6 speed, i would see it putting between 460-480 at the wheels, maybe even close to 500.

I have a customer by the name of Xessive in TX that had a customer bring in a truck with a 6.0 engine in it and they had installed TFS 235's and it actually made 500 RWHP, which shocked me, but the TFS 235 intake port only measures 230-231cc.
We've had a LS2 Corvette make 507 RWHP with the TFS 225's, and I just had a guy in Canada with a LS 2 Corvette make over 500 RWHP with the TFS 215's.
So I would say if you are planning on nitrous, use the TFS 235's, they are wicked on the spray. I have a customer with a 402, TFS 235's, our 250/266 N2O cam, Fast 90/90, pump gas engine (on race gas of course) run 8.80's in the quarter mile at 3500 lbs on 2 stages, he was happy.

the only differences will be, the heads/rockers & bullets off the headers vs. choking y-pipe and the patriot heads. it did 480/435 before & ran 7.30 @ 97mph 1/8th (3700lb raceweight, 3.89 gear). its lost 100lbs & has 4.30's in it so i'm hoping for some 6's & 10's in the qtr.

I have a 370 with 225s on it with a 242/256 on a 133lsa, raceweight of 3480 first pass with the combo went 10.82 at 124 which impressed me since it is a nitrous motor and the car has NOS converter 28" slicks with 3.73s. Talking about a mismatched combo and it it still runs a number.
TEA has got my vote Ive bought numerous sets of heads from them and all of them turn good numbers
