any 370 with l92 combo
I have a local friend with a iron 370, Trex cam, and unported L92's. He made ~480rwhp with crappy MAC mid length headers. We are expecting near 500rwhp with that issue fixed.
His screen name on the board here is "Nice SSer"

I have an Iron 375ci short block (built by NICK @ ARE IN LATE 2000) TSP CNC'D L92'S, COMP 236/242 640/647 112 , UNPORTED L76, Grotyohahn 1-3/4 - custom 4" y-bullet dump. 440rwhp/410rwtq
This is through a 4L80E w/ YANK 4200 STALL, 9" W/ SPOOL & 3.70 GEARS & 325/50/15 MT DR'S.
The setup I run isn't ideal for max peak power but I wanted the power to hit a little late due to the fact that I mostly street race and I wanted the power band to be like it is. FWIW THE TQ # IS WITH THE CONVERTER LOCKED. I didnt care about the unlocked TQ # as I typically lock the converter just after getting into 2nd gear on an NA run so thats what I needed to see.
I also have 2 kits on the car and with an all billet/cryo treated 4L80E, I can lock the converter in first gear and turn on the gas.That is where this setup shines.
I'm planning the next step now with either a new cam and carb style intake or just building a new 427/440 or ? My engine is old, headers are costing me some power and i think it may be the time to start over with a fresh short block.

Since I last posted Ive went through a few combo ideas from a 402/APS TT, 440 LS7 HEADED SHEET METAL INTAKE SETUP, etc.... Ive decided to keep my spraying my current short block until I drive over the crank. I am going to spec a new cam and headers next week and get them installed and remove ~ 150 or so lbs out of the car.
