I am going to check with a local exhaust shop, maybe he can make an H pipe cheaper & then run a 2.5 exhaust out the back.
Which is the better way to go: shorty or long tube headers?
Does the 88 Bird motor have 19lb injectors?
sd = Standard?
If I don't add the MAF will I have a check engine light on all the time?
Thanks much!

Sd= speed density. Maf is mass air flow sensor.

Birds/cats have 14#ers

Read up coolcats.net under the h.o. conversion. It answers almost every question you have asked.

Thanks for the link! after my last post I went to the link & found the conversion section you mentioned & then I felt like I was wasting peoples time cuz like you mentioned it does cover just about everything I was asking. So sorry about that.
1 thing the procedure didn't mention (at least not from what I have read so far) & I am still curious about is the headers.
Long tube or shorties which is better?
Again THANKS to ALL for the help!!!

Depends on what you want out of the car.

Long tubes interfere more and easier especially with steering linkage and shift linkage.

If the car isn't tuned properly, you can lose some bottom end, but bigger is almost always better.

Shirties are easier to install and have less interfearance.

I recommend the BBK 1515, like Beau said they are purdy and they are compatible with the GT40 heads.

Something I heard years ago about 5.0 HO roller camshafts : The 1993 5.0 Mustang Cobra used the same camshaft that was in the mn12 5.0 HO motors, slightly milder than the previous HO camshafts in the 1987-1993 non-cobra 5.0 Mustangs. The difference being with the Cobra having 24lb injectors, gt40 heads and 1.7 roller rockers whereas the 'Stang and mn12 5.0 HO's used E7 heads with stamped rockers and 19lb injectors.

Also there was a desired 1987 5.0 HO roller cam, early build that was more aggressive than the later grinds.

I don't know where the 1994-1995 sn95 Mustang 5.0 HO camshafts fall under

I'll bet there's less then 5hp between them. Just stick with which ever you find cheaper and in better shape.
