I have a 91 F-250 with a 5.8, I have a chance to buy a complete 95 F-150 with a 5.8. Is the 95 most likely to be a mass air (have not seen truck yet) and if so how hard would it be to swap it over to my 91. I am not a electronics guru, I am old school but I would really like to convert to a mass air if it isn't to complicated. Also it is a mass air if it has the air meter in the intake tube correct?? Thanks for any info that could help.

I would really like to put the 95 front clip on as I like them much better but don't believe I want to go through that trouble. There may be lot's of parts up for sale if I go through with this.

 

most 95s 351w I have seen arent but could be does it have a sensor at the airbox if it does its mass air

 

keep ur old wire harness and keep it speed denisty would be easier

 

Look under the hood at the air intake system. I believe if its MAF it will have one tube approximately 4-5 inches in size from the air filter to the intake, if it is SD it will have two tubes running parralell approximately 2 inches in size.

I am not 100% sure on this so if I am wrong someone correct me.

 

Yes. If its MAF it will have the meter in the intake tube, but I don't believe the 5.8 went MAF until 96, if you have a late model 95, it could possibly be MAF. However the 95 will have the roller-ready block, casting # "F4".

A MAF would be nice. You would be able to run a choppier cam with MAF and even do some head swaps or something to greatly increase air flow, However what trans doees your 91 have? I have a AOD, so if I did the swap all I need is a SD to MAF wiring harness and a Mustang EEC. If you have a E4OD it make the swap more difficult. I don't even know if a 95 EEC will operate a 91 E4OD trans, someone else might know.

As for swapping the front end, its possible I guess but the frames are different b/t the 91 and 95. So if you want that front end better be ready to do some modification.

 

I know it would be easier to stay speed density but I would much rather have mass air.

SCRebel, of course I have the electronic overdrive, things are alway's on the complicated side for me.... Also I am not going to swap out the front ends, I would like to and know it can be done just don't want to go through that hassle.

Thanks for the info guy's, appreciate it.
