70mm or 75mm TB?

Stang Runner · 08-09-2001, 04:10 PM

TFS heads and holley intake, I will get when the $$$ comes I know 70mm is the right one but would a 75mm help me get a few HP up high, in the RPMS I and going for Top speed power.

Stang Runner:

A 70mm TB is fine for your combination.
Bigger is not always better.

The 70mm TB might even be a bit big.
