LOL screwed 2V you must be a multi millionair, must be sweet to have some insanly fast cars....anyways you really dont need much for 12s. If thats your goal, (420 RWHP should put you into the mid 11s on slicks @ somewhere near 120...my guess) then I would leave the heads/intake (new plenum with plastic stocker will be fine) alone...cams would help and that would be up to you, and push about 12 PSI of intercooled boost...that should get you to your goal. FYI a guy with forged SB, stock intake (plastic...the car was a 01 salleen I believe), stock plenum, MPH cams, exhaust, novi 2000, intercooled, 17.5 PSI (I believe) 601RWHP...nuff said huh? I believe he had 9.0-1 compession, I suggest at least going that. (01-04s got 9.4-1 compression..99-00 windsor SBs got 9.0-1) Basically I said that to show what your car would be capable of, ofcourse that was with Tim's unbeatable tune.
