Sounds like it's time to do some port work. A little grinding here, alot of grinding there, and some spit and polish on the way out.

Oh, and I didn't see it on your list, but if you haven't already you can grind the restrictor plate off of your throttle body butterfly, and also relocate your air temperature sensor. :thumbup:

Well there good buddy here is what I would do... wait this is what I am doing. 1.6 roller rockers I have the crane gold, but you dont have to get the most expencive. Cam either camp/Crane both real close I am running one with 276/270 dur. this will put the power plant at 2000-5500 rpms. COme new springs to match your lift. I would do a Stall like 2500-3200. Probably a new torqe converter they make a Nitrous one. Port and polish the heads wont hurt any either, but I would drop in some forged pistions first. Then maybe a crank to finish the bottom end. If yo still have some money left hone out the throttle body and if for some reason you still have money have the PC sent out to match all the work you just did. Happy track to you
