75mm throttle body question

jinx6570 · 11-11-2003, 09:42 PM

I need some help with a throttle body purchase. I want to put it on my 97 GT but can't find one for it. Will the MAC 75MM throttle body for the F-150 work and if so are there any modifications I'll need to do? Thanx for the help.

On a 97 gt wouldnt a 75mm be too big? Everyone says the 70mm is too big for the 96-98 gt's unless you have a PI headswap or blower.....

75mm is worthless. Save your money. Only so much air can be sucked into you engine and the T/B is not the restriction. The restriction is the intake/heads combo. Change those and then you need a bigger T/B.

P.S. - I finally got a C&L maf off E-Bay for a 100 bucks and it really helped my top end! If you don't have one check one out. Much better mod than a T/B, even if the C&L gains are minimal.

Get something else.

A 75mm T/B on a stock 97 is worthless...
