here is my delema, i have a 98gt w/aode with some modds. i am currently getting ready to install pi heads & intake w/comp cams XE270AH & comp cams valve springs PN26113. i am having the heads ported, i am trying to match the article i read FILLING THE GLASS in 5.0 mag. from my august issue. i am worried about my transmition, i have read on some of these forums that a lot of you guys have built trannies. i need as much input as possible (how much $$, what company to go with, what parts to use or look for) to help me make my choise on what to do. if i play my cards right i'm hopping to run about 450hp to 500hp from the setup. i know that i should build up the block because 450hp is pushing it to the max, but it will have to wait till i get the extra $$ to do so. with some conservative tunning i hope to keep it between 400 - 450hp. i know that you guys are saying that i may be optomistic but from what i read this setup w/out the supercharger this combo dynoed in at just over 400hp and 390 lb-ft of torque on a basically stock motor. with the supercharger (vortech) it belted out 648hp and 545 lb-ft of torque. not to shabby.. the supercharger that i am running is a very cheap one (powerdyne) but it still works so this is how i am estamating my #'s. so please give me all the input positive or negative to help me out. thanks, ron
