Will an Explorer intake and GT40p heads work without problems on a speed density car? What kind of power increase should be expected? Thanks

 

They should work with no problem. From what I hear, mass air conversion is not that difficult either. Gt40p heads are not the greatest though. The intake is pretty good. Making power in the 302 mustangs, good heads make a lot of difference.

 

I just bought an Explorer engine, to put in my 85 GT. I already have a set of alluminum heads to put on it. A friend of mine has a Lincoln LSC 5.0 that has speed density, and was wanting to mildly mod it. I have no need for the intake (carb car) or heads and figured I could help him out. but I've always heard of problems modding a SD car.

 

It's just more difficult to tune a SD car. Mass air conversions are usually the way to go.

 

Thats just not something he wants to fool with.

 

Stock for stock a speed density car they say is a tad bit faster. Minor bolt on's don't usually cause any problems, it's when you start changing the cam and etc... that you will start having some issues. changing just the heads and intake alone will not cause any problems.
