I will be installing my 6.0 lq4 soon on my 99 GMC in sig.
But I can not decide on what cam to go with:
I am looking at the following cams;

My current one - 222/224 .566/.568 112LSA

and also these - all of them with my choice of LSA

TSP XS Series Camshaft: 228/228, .588"/.588"
TSP XS Series Camshaft: Magic Stick V.3 237/242, .603"/.609"
Texas Speed Torquer 2 232/234 .595/.598

Which cam should I go with and what LSA

I will keep my 3000 stall, new 918 springs and hardened push rods. Push rod length?

Any help will be appriciated.

 

well the second one won't work cause the lift is to much for the springs, but i would go with the bottom on get it on a 112lsa

 

Is there somebody running the 232-234 .595/ .598 cam on here.
good ? bad?
Is anybody running it with forced induction

 

quik ran that same cam in his truck..but he also had an lq9 with aftermarket heads..he was runnin 11.0 compression ratio..to run that can i would at least put some 243 heads on it to get the compression up

 

I like that texas speed torquer cam. Im doing an lq4 build. Havnt decided on a cam yet. But that cam is looking nice.

With your setup I think that 228/228 would come out of the hole nice and pull hard all the way to the end of the 1/4 and more. IMO you might want a little bit more converter then 3000 for the other 2 cams. ANd for the over 600"lift cam I personally would run dual springs to be safe.

LSA if you plan on spraying it get 114. If you are doing an all motor do 112

 

226/226 .581 .581 112lsa

 

I had the TSP TV2 112 in my LQ9 which had stock 243 heads and that allowed me to have 11.1 cr and i also ran the LS6 intake

MS3 would destroy the 918s you probably could get away with it for a very short time till you just destroyed the springs

228/288 is a thought for a lower compression motor

i had the TV2 up for sale but decieded to give it to the GF for her TA


i also used a 3800 stall for the TV2 and i used 7.4 pushrods along with 918s

 

quick how did that setup work? Im lookin at something similiar but with worked 317's, 10's comp, dual springs, and 3400 converter.

 

with my fuel psi it went 12.59 which wasnt bad knowing it fell on its face on topend. at WOT my fuel psi would just be insane [no gauge] but it looked like i was a diesel and would just wash out some spark. it was deffently a strong setup even with that issue. now my old motor now has the Trex cam and is going in a camaro

 

Would you go for a wider LSA? I am going to try a Vinci XXX ( DUR @ .050" 222* / 228* LIFT .551 / .551 OVERLAP 57* LSA 115). I'll let you know how it works pretty soon.
