should i go w/ a 65mm or 70mm throttle body for an early explorer intake? i hear the intake opening is 70mm. I will be putting on GT40 heads with the stock cam or a mild aftermarket one.

go with the 70mm. as long as it fits.. I know the factory intake for the mustang isnt large enough, but not sure about the exploder version

...Go with the 65mm TB

Second the 70mm.

dudeboy

70mm or maybe bigger...


(Here comes the 'low end velocity' guy though....)

FivePointOhh

if you arent doing heads or anything and you're staying fairly stock. 65. if you are going to continually upgrade, go for the 70mm

OnyxCobra

you might as well go with a 70mm.

looks like the 70mm tb take the win!! As for brands, i was thinking Professional Prods or BBK, but I always here of BBK TB's whistling. I did hear you could stop the whistling if you smooth out the outer edges of the IAC passage.

ive heard it too..but my bbk never has whistled..maybe im just lucky

70mm and go with holley or accufab
