l92 6.0 setups? Who has them? Can i get some info or dyno numbers? I cant find much about smaller motors with l92s and l76 intakes. Anything in the 364 to 376ci area dynos would help. thanks

The ones that run/dyno the best are running fairly small camshafts. The L92/LS3 heads don't need or like as much overlap as cathedral port heads and they can make very strong power with less duration on the intake side. Basically, they respond with a later opening/close of the intake valve. The exhaust duration of the new heads needs to be around the same as what worked best with cathedral ports although they flow slightly better in stock form than the old heads.

what about LGs results with the ls3? Those seem to be the best i have seen...
I am hoping to make 450rwhp though a 4k stall and a th350. Does anyone have any SDPC ported l92 results?

so do you have any results from cams you have speced on l92 setups?

this is from another post but i have a trex laying around. I was just going to port the exhaust side of the heads and slap them on. i would love to see the dyno graph from the post below i sent him a pm but he didnt reply.
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"
