I have an lq4 with l92 heads ls3 intake I was wondering what's the biggest cam I can fit without worrying about PTV issues

Will I be fine with a 231/243 .617/.624 LSA 112 without having to flycut?

I personally think so. Tooley have a square port (LS3) cam that's around 233/248 duration that's doesn't require flycutting but it's really tight on the ptv deal. With a LQ4 you should have dish pistons which should give you a little elbow room. I would give Tooley a call or another serious cam guy.

Another problem your going to run into is that with a big cam, big intake port, and low compression that motor is going to be a real turd at low RPM's.

I agree with you.... just depends on what a man wants lol
