l92 6.0 setups?
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?

yes the problem is everytime i pm somebody about a setup i get no reply. I am going to call sdpc and tsp tomarrow if i get time. i just like the bottom end these heads make for the street. My old 408 with etp only made 440ftpd of torque. i would like to see over 460

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"

i have the same question, i just picked up a stock short block lq9 and was wondering what to do. i need it to run extremely reliable sense it is replacing a used motor in a DD.
