ok, stock 5.0 TB is 60mm right?

are factory manifolds capable of fitting a 70mm TB or do I need to port the intake?

factory MAF is a 73mm unit right?

thanks

you'll most likely have to clearance the opening

Shelty

thanks....

kinda thought that, just wanted to double check...

I saw the new Edelbrock performer RPM II intake on Summit's website... me want me want, but for 800 bucks....

87 - 93 are 60mm, 86 is 58mm

You could use a 70mm EGR spacer witht he 70mm TB but your still going into a 60mm opening. I did port match my factory intake to my BBK EGR spacer took a lot of patience and a few dremel stones to do it.

Here is the finished intake next to a un-touched factory intake.


And here it is next to the Explorer GT40 intake.



No it is 55mm the 93 Cobra was only 70mm.

Don't use anything bigger then a 65mm TB on a stock intake; 87-93 GT & LX TB, 60mm...stock MAF 55 or 58mm??

Shelty

thanks guys.. just wanted to clear that up, cuz I noticed that Pro-M MAF sensors are calibrated for 19lb injectors all the way up to I think 76mm....
