what do you mean giving away tq? I thought those intakes helped.
i only plan on getting a 3k stall, doing those heads an intake, and getting a cam no smaller then 224/224 .581/.581 112 lsa
no spray no FI i am going for ALL motor

the truck intake creates greater torque and if you plan to stay N/A the truck intake is the only chouce and if you are serious about that cam with L92's then you are gonna be disappointed.....the heads have VERY lobsided flow, meaning the intake WAY out flows the exhaust which has to be made up by using a dual plane cam grind ie the split....a single plane cam will be a TURD with L92's

if that cam is really your choice then find a set of 243 cast CNCed heads, here's a set new in the box for sale on a TBSS board (FS: Brand New Patriot LS2/243 Stage II Heads Assembled & LPE GT2-3 Camshaft... - TBSSOWNERS.com Forums - The #1 TrailblazerSS Dedicated Owners Forum)

+1 You can't put that cam in with those (L92)heads. When the time comes Ricky we'll get you a cam and it won't be that one. I informed you that you lose some low end torque with the car intake over the truck intake. You prob. need the truck intake since your staying N/A 6.0L, 80e, no power adder RCSB. I might just have to do a dyno comparison between my ported L76 intake and the L92 intake, see what the difference is on my setup. Which ever is better, I'll go with but, I want to try it and see. I'm the duckling that never stayed in line. Here's the flow between the two. These are factory pieces, wait till the fast or weiand comes out. I just know the truck intake dies up top (what 4500rpms?). Pick your poison on this one.

[skeet]

the head and cam swap is complete!!!


l92 heads

patrick G spected cam

i used my 42# injectors with my edelbrock fuel rails, also with my 90mm cable TB

i made brackets for these, i am finishing up the final bracket today, well ok a friend at work, if i can spare his work load today

wanna thank melissa for getting my tune out, wanna thank bret for doing the brackets ( fawker did them on OT) lol


Wanna Thank DBTBSS & FreemaSSon for the input thanks guys



on another Note i talked to quite a few cam Gods lol and yes the split is the only way to go, after hearing so many cam specs and all of them falling into or close to the same catagory, i talked with patrick and made a final decission..Now how this setup will preform, well i will find out soon...

[PurpleMinivan]

No problem at all. Let us know how it runs, videos are great! If they're not top secret, I'm curious what cam specs are? I'm sure Patrick G took care of you.
