High End Hesitation

[Welcome_to_Ford_Country]

My SHO is putting out about a third less the power between 5500 and 7000 rpms than another stock SHO I have driven a bit over the weekend. I have been sensing this for a while but it was confimed after driving my friends 89. Secondaries are opening fine. Any suggestions?

60k done?

Have you checked fuel pressure?

How old are your plugs and wires?

60K has not been done since the engine has been in possession of me or my someone i know . Probably 20,000 miles. Plugs and wires a few thousand ago. When I pop the hood i smell gas- How do I check fuel pressure? i guess I can find that out myself. thanks.

Clean your MAF if you havn't done so already. It's cheap, easy, and I can almost gaurantee that will make a difference in throttle response and performance. It made a huge difference in mine anyway.

Exhaust restriction? Damaged cats?

Thanks guys- I will be looking into your suggestions except I don't think it is the exhuast- I just put this y-pipe on when i finished swaping this engine into this car last week. There were no problems in the other car that is was in.
