I did the ms4 cam swap last year with prc stage 1 ls6 ported heads in my 02 camaro. Car also has 1 3/4 LT's, slp loudmouth, lid, bellows, 4000 stall and a fab 9 with 4.11's and drag radials. It was dyno tuned and made 406 hp and 389 ft/lbs torque at the wheels with this set-up.

I'm not happy with the track times...11.8 at 115 with a 1.67 60 ft. shifting at 6400 rpm. I think it should run mid 11's at least...so my question is to others with a similair set-up,do you think the stock intake and throttle body is holding my car back? Would it be worth going with a FAST 102/102 intake and throttle body?

That's a mighty big cam for the stock manifold (as good as it may be).

A 102 combo portmatched to your heads should gain you a .2-.3 tenths and a few mph, so you might be able to hig 11.5 but it will take very good driving.

Those are better than respectable times; well done. You could either open the inlet size of the LS6 intake or go FAST. IMO, moving up to an 85mm TB & opening the inlet of the LS6 intake to 85mm+ will help. Either option (FAST/LS6 mods) will help reduce your times.
