on a stock ls2 with 243 castings and 2.055 intake valves?
i would like to not have to flycut the pistons if at all possible.
anyone know???

I read where anything (LS2) with stock pistons stay at .600 or less. Any more & the clearance starts getting close
so any valve float would contact the piston. They listed duration numbers also being a factor if the numbers are too big.

i think it will have more to do with the duration than the lift, but i plan on staying around or under 600 lift anyway

Bigger is not better, have a cam spec'ed out for your needs and setup.

dont go biggest cam, go with something like a g5x3 or g5x4 (if it will fit). Again as someone else said the biggest cam isnt always the best.

call any of the sponsors on the right, tell them your goals and setup. They will recommend you a cam.

thats what im trying to figure out what will fit. not what is the absolute biggest cam i can fit. im wanting like a 232-236 600 on a 114. i just dont know if it will clear with valves that big

Look at my cam specs in my sig. I have had no issues.

Make a phone call and talk with a specialist that can set you up with what you want out of the cam

You can definitely go over .600. Mine is .630/.630 and I have no problems.

Man your combo sounds like a deathtrap.
Not really just wanted to use your name.
Well... You asked what is the biggest cam you can run w/o flycuting.
That is a impossible answer to be 100% sure. Many of us could give a accurate guess, but to be 100% wouldn't happen.
You have increased the valve size on the intake, do you mind if I ask why?
Why do a valve job, and bigger valves and not port, mill, etc the heads?
Especially if your now flycuting the pistons, I would take the heads right to the machine shop and have them milled to raise your compression somewhere around 11.5:1. For a LS2 motor with LS2 heads that is only about 20-25 thous mill. OR I would run a .040 gasket and not mill the heads at all.

Have you considered spending a little extra money and buying a set of Trickflows or ETP heads? These both free up additional P/V clearence over stock heads which would save you from having to spend the money/time doing the flycuting.

I have seen some great results with the cam you choose, and even better results with added compression, and aftermarket cylinder heads with that cam.




Also what

well i guess i could give a little more info lol. now it looks like im going with a 2.040 intake valve since im going with the tea stage 2 heads. im wanting to keep my compression around 10.5:1 because i plan to spray a 100 shot as well. the flow #s are almost identical to 215 trick flow so im hoping for the same out come

Well on a stock LS2 shortblock with a 243 head your gonna be just under 11:1 as the LS2 motor's have 10.9:1 CR.
Also flow numbers aren't everything.
TEA ports the trick flow heads.
I deal with both company's, and even Brian Tooley will tell you the trick flows out perform their ported LS6 heads. It is a tough comparision. You dealing with 2 completly different heads, and port designs.
For what your spending on the LS6 ported heads a few extra hundred and you could be in a set of trick flows, especially after you sell the stock GM heads.
And there are hundreds of 11:1+ CR setup with nitrous doing just fine.
