I picked up my 1990 5.0 LX with the following mods, can someone ball park the HP on my ride. I just don't want to pay for a pull on the dyno, going to wait for a free pull at an upcoming car show. My mods are as follows:

87 T-Bird Positrack rear end
3:73 gears
Mosler 31 spline
4 Wh DBreaks
GT-40P Heads
Cobra Upper/Lower Intake w/ 3/4 BBK Spacer
FRPP UD Pulleys
BBK AC/Smog Delete
BBK H-Pipe
17 Cobra (rep) Rims

Thanks Guys!

I'd guess around 290-300 flywheel, 235-250 rwhp.Stock: 225Heads: 25Intake: 15Pulleys: 10AC-delete:5H-pipe: 10These are all ballpark numbers. Plus, if it hasn't been tuned, you might see lower numbers. You will also see lower numbers if using a Mustang Dyno (as opposed to dynojet). Do yourself a favor and throw in a mild cam (either E-303 or F-303 to stick with the FRPP top end). But as the old saying goes, "horespower sells cars, torque wins races".
