Resolved I need a guide installing a GT40P Cylinder Heads and 97 Explorer Upper/Lower Intake

[Mhalc1]

If you are running 19# injectors, read up on 94/95 MAFs on the fox. Lot on this topic out there


That’s what I have here. Just need an adapter

Thanks, im reading up on the swap as we speak

What does the 94/95 MAF gain you? Not being a smart ass or anything but with 19 lb/hr injectors what’s the gain?

It’s 70mm vs 55mm. That’s the only benefit. MAF transfer curves are essentially the same so it’s a plug and play way to get a little more airflow. You can swap the housing out for the 91-93 cougar housing if you don’t want to run an adapter, but you must use the 94-95 electronics with that housing.

Obviously if you choose to run larger injectors you need to take a different course of action, but that combo will run fine on 19s. You might be near the top end of duty cycle range however.

As with anything. We can scope creep the hell out of that combo. But my point was showing a more budget friendly way of putting together a basic GT40/p combo using as many OE parts as possible. There are better parts, but you’ll pay more.

I started out with GT40P heads, a used TFS1 cam and a explorer intake and TB…and look what scope creep did to my combo

Can you link me the parts that I need if you insist?

You can also use the 70mm mafs from early 90’s crown Vic and Marquis
