L92 info

Found this article doing some head research. Pretty good info.
Testing The New GM L92 Cylinder Heads - Car Craft Magazine

looks like they got good numbers, im waiting to see if trick flow comes out with a set of L92 style heads cant imagine what they will make :)

thats nice,giving me second thoughts

Yeah I've read that article, I was rather impressed with the numbers they got. If I go lq4 or lq9 that's one of the first upgraded I would probably do.

i got on the rollers yesterday, just to see where i was at with the rwhp numbers, we gained 10 ( in the heat ) from a 440 to a 450, by going from a dynatech long tubes to kooks 1 7/8 to 2" steps into a 3.5 collector into a Y pipe. thats the only thing we changed from the ECSB to the RCSB and gained 10 rwhp ( not bad ) right now i am having a cam spected out once again, hoping to push closer to the 500 mark on rwhp ;) we'll also be making a few other changes to reach that goal, mind you this is on a lq9 short block with l92 ported heads

I need your old headers then.

WE are using a set of L92's on the latest budget build. :) http://www.ls1truck.com/forums/power...est-truck.html

The one thing i wish they had done was dyno the heads separately from the carb and cam.

man this just makes me wanna go FI!!!!

if i decide to sell them i'll let ya know, right now there on the ecsb, with a stock 6.0 with a tune lol.. thinking of doing some more dyno comparisons between headers, even though i gained up top i lost down low, and we both know the TQ is where its at with these heavy trucks ..

L92 heads don't perform :lol:
