Sorry to but that is the exact dilemma I'm in now, do I got MS3 with 2.5 5.3s of MS4 with Stg 1 LS6. Anyone have any thoughts?

Not to hijack but that's who is doing my H/C install next week if all of the parts come in. I'm going with a Torquer 2 on a 112+4 though. First cam and I guess I just want to have a better chance at keeping it streetable lol. Dynoed 351 HP and 378 TQ with a rich 11.68 AFR with mods in sig. Have to see what it does after the H/C install and tune

I made 435/402 with Torquer V3, on an ls6 intake/tr6.

Nice, I'm hoping for something similar although mods are a little different. I'll be using unported 243 heads but I'm wondering if I should get them milled to increase CR

Do you have a dyno sheet? I'm not seeing how your TQ# is that close to your HP #. Usually when the #'s are that close its a small cam motor or a stroker.
Big cam, stock cubic inches and ported heads = HP much higher than TQ. Not calling BS or anything but would like to see a graph if you have one.

Just installed PRC Stage 2.5 5.3 heads with MS3 cam and full boltons and only pulled 412whp and 36*trq on a m6 car I think/hope his stock clutch was slightly slipping So we are going to try that next. Because my 99 cam only m6 with tsp 231/237cam with full boltons put down 413whp 380trq with 111,000 miles

Definitly somethings wrong there, my MS3 with stock heads made 411 in my 99 SS. Check that clutch and maybe your tune needs a little tweaking.

I am definately leaning torwards the 5.3 2.5 heads does anyone know if they will clear if the MS3 is on a 111 lsa?

Yeah the TQ was low, but it did trap 119mph in the 1/4...
