Don't mind EvilMooseofDoom
..He had a 5.0 Thunderbird once, and well..I don't think that project really ever got off the ground..
Don't get me wrong he is amusing at times though..
I really don't understand what he means by "holding back the motor" either..
The exhaust system routing on our 5.0 MN12's is more of a restriction than even the shorty headers that come stock on our cars..
Especially the driver side catalytic converter..Look at this thing!
In all honesty our stock shorty headers are not really that bad..What we gain in HP using the SCP Headers vs the stock shorty headers is minimal..
The point is..You're not building your 92 for drag racing..So there's really no point in discussing why you need every last HP available for street duty..
With your new exhaust, and scp headers the only exhaust restriction I see on your stock headed 5.0 is your catalytic converter set-up..
Besides..You're not pushing enough air out of the engine to necessitate big headers anyways..You've got stock heads for god's sake!..
For some reason it gets preached over and over
that everyone must install a manual transmission in these cars to make them fun..
Oh, and you have to install long tube headers as well, or your stock headed engine will be losing a ton of horsepower..../end (sarcastic rant)..
Definitely add some gears when you get a chance..You're not going to see any HP gains, but the fun factor goes way up..
Isn't that the point..Having fun..
