build the lq4??

[banker099]

The stock L92 intake was enough for my LS3 418 up to 6700rpms. Single cab truck 9.5-1--10-1 CR, 230's-.600 112-114 cam, 3600 stall with a healthy shot would be interesting...

thats pretty much the plan...at least 10:1 though, high compression and good heads is the key to power

Or you could just put some decked 243/799 heads on there to really bump the CR up... 10.5 to 1

did some work tonight, this motor is filthy


its definitely an Lq4


some of the parts i did manage to get clean, minus the rocker arms...lol

looks good Ryan! should be a cool build!

[skeet]

those edelbrock intake are MIA from what i hear, ive still yet to see one on someones engine,

what are the rpm limits on the factory L92 truck intake?

i figure around 6800 probably max, i shift at 6700 - 6800

so i guess i can always go with a thinner head gasket as well....assuming they make different thicknesses for the l92's

they make different thicknesses just use a 6.0 head gasket!! if ya gonna stay NA shoot for a 11:1 cr, i am fine with it and i drive my truck daily. whatever you do, talk to some cam guru's and have them spect a cam for you. only difference is i am running a lq9 i had my heads milled .015 then used a .040 mill gasket.

DBTBSS is very familiar with these heads as to another member on another site, that i followed when i built my motor, i just did a few things different

cool yeah i will most likely be running the stock l92 truck intake then,

i didnt know if i had to use the l92 head gaskets or if the 317 head gaskets would work, but now i guess they are the same so i can go with the thinner ones for an extra bump in cr,

i would love 11:1 but its gonna be hard to get that with an lQ4

I am dealing with the same dilemma. I wanted to go with the L92 setup BUT there's just no way I can get the comp up high enough (no less than 10.5:1) with the lq4 shortblock without worrying about to PTV issues. I think you're better off going with a ported set of cathederal heads (really nice ones though, no TSP junk, etc) It'll cost more but you won't have to flycut pistons or worry about over revving.

Why not just LQ9 pistons?

+1... Well said! Another victim maybe? lol
