i have an 07 classic with a Vortech Twin Screw. im in need of a larger tb thats dbw. i have looked thru summit and they dont have much for dbw apps. i also thought about a corvette tb but am unsure of which to get or which will fit.

 

If you have the 3 bolt TB, then you can get a 87mm off a nnbs but you'll need a dr. X harness, and you intake will need to be able to accept it, 4 bolt vs 3 bolt.

 

my tb is a 3 bolt and thats all my sc accepts. any ideas

 

buy the 3bolt to 4bolt tb adapter plate, a NNBS truck or LS2 throttle body, and the drx harness and youre all set
