pro flo ls1 to ls2 throttle body.....
the intake is the 3 bolt design, but also has other threaded holes, and the nick williams tb is the ls2 4 bolt design...... the other intake holes match the top 2 throttle body holes where the bottom 2 holes are 1/4" off......... what is my best option here???
i purchased them both awhole back and just now got around to bolting it all up..... i dont have the orig receipts or boxes anymore.....
do i have the 2 bottom holes welded shut and redrill where needed and tap? and cut myself a gasket???
Plenty of other adapters out there if you search.No need to drill/tap the intake.
