I plan on changing the cam, had the one in it spec'd by Guerra Motorsports, it's an excellent cam for my n/a set-up and probably the converter we'll see. Had PI build it, for spray, and so it would trans brake to 3800 and i wouldn't spray through it hope it won't be to tight for the FI setup. If not probably going with a Yank PY3400E that's what came with my 4L80E but was way to loose N/A. Going to run the LS6 heads the way they are. Hopefully DC_Justin will have me a tune next week. Can't wait.
