Hi, im currently working on my 5.0HO T-bird. (i know, i know  but the question is engine related) It's gonna recieve the intake of a Mustang H.O (ported upper/lower) Some portwork/milling on the heads. The exhaust is changed, no cats at all, 1 Flowmaster with dual exits exiting before the rearwheelNow i was looking at some more HP.. not mayor figures , but some more than stock.. I was thinking : 65mm throttle body,70mm maf, E303 cam, and a fuelpressure regulator for some more pressure. Now , first how does this sound??? second, how far can you take the original ECU or do i need to upgrade this also?? Third, can the valvetrain (springs..) take the higher lift from this cam.. or do you say, do the work on the heads and intake, and leave it at that again i'm not looking for 300+HP numbers, just something more than stock.. (it's a low budget, nascar transformation) greetz Ben

Good cam choice and TB. Use a Aeromotive FP regulator.
Skip the MAF.
That's about the limit on the stock processor.
You will need new valve springs with that cam.------------------

You won't turn enough RPM to worry about it.
I back to back tested MAF's on 89 our HO convert when it had nothing but headers and a very mild cam and new springs.
It still slowed over 5500 RPM and slowed even more with the larger MAF. (s)------------------
