5.0 build up
I want to build up my 5.0 in my 90 f150. It is a '94-up reman on SD. I've done some research and this is my plan:
-Trick flow tw 170cc heads
-comp xe264hr-14 cam
-stock truck intakes, gasket matched lower
-1.7 roller rockers
I have a couple questions. The heads come in 58 and 61cc combustion chambers. How much better performance wise would the 58's be? I'm worried about PTV clearance issues with the 58's but trick flow says stock pistons work with the 61's.
I want to go with 1.7 rockers but not sure if it would push the limit with the cam and SD. Also, I already have the '94-up truck cam so would the cam swap be worth it??

If it's a roller motor then definitely do the cam, I would go with 61 cc chambers just to keep closer to stock CR. Shouldn't make more than a half compression point difference but still. The rockers have no effect on the computer, if your cam is compatible it will work either way.

No.. port matched lower.
This combo is well beyond what SD can adapt to, and you need to make sure the valve springs can handle the lift without binding.

You tell me.. what are they spec'd for in terms of lift?
It is technically but but only in terms of valve timing events, if it was the only thing changed in the motor it would run reasonably well. But you are also adding cylinder heads that flow a lot better than stock.. maybe double, all that extra air will need extra fuel but the SD system has no way of knowing this so it can't possibly compensate. What you will need is larger injectors and then a tuner(with a compatible PCM) to dial it all in, a Lightning PCM would be the choice if you have an E4OD trans, but if you have a manual, C6 or AOD then I'd suggest just doing a MAF conversion with a Mustang PCM.

According to this link: http://www.trickflow.com/partdetail....S-51410010-M58 valve spring maximum valve lift: .600"
It is an AOD trans. It is recently rebuilt with a transgo shift kit. Will it hold up to this setup?
I'm interested in doing the maf conversion. Are there any kits still available? Thanks for your help

I'm not sure I understand much of what you are asking. But what I do know is the AOD trans is a very durable trans. I don't know what kind of HP or Torque your trying to get but again the AODs are pretty bullet proof. I have owned them. The last one I had was in an 88 T-Bird with a 302 HO engine. Other than serving the trans it saw 190,000 miles with no issues. A friend who was a tranny guy told me the AODs were very good transmissions & just to keep it serviced & I would get dependable use from it for a long time. I drove that bird pretty hard. That 302 was no dog for its era.

There are some but they are pricey from what I remember, a much cheaper route would be to build your own with salvaged parts from a Mustang or T-bird.

Am I wrong in assuming I could just swap in a computer, engine wiring harness, and intake tube from a donor 5.0 maf truck/car? If so would it have to be an aod/manual trans car?
Also I would need to run two o2 sensors as well, correct? I am currently running headers/duals/no cats as well as a full emissions delete (no emissions in my area) I assume this wouldn't pose any problems except a CEL.

Not necessarilly but if you get a Mustang computer and you have dual exhaust then it's just as well you do.

I found this maf conversion harness for 86-88 mustangs. http://www.jegs.com/i/Granatelli/467...6X7hoC9Ujw_wcB Would it work for my truck? If I got a maf sensor, intake tube, and an 86-88 mustang pcm?

Thanks for the info, didn't know that about the SD mustangs. I found this kit on eBay: http://m.ebay.com/itm/301673310182 seems like this would be a much simpler option even though I would still need the intake tube from a maf truck. What do you think about this one?

That is a more reasonably priced kit with almost everything you need, if you can source the intake Y pipe and an arbox that will fit that MAF meter from a junkyard you're all set. You should ask them what PCM is inciluded in the kit.. hopefully it's an A9L or A9P Mustang PCM.
