I've got a 1987 5.0LX, 5spd standard transm. and i've added these modifications to it. Centerforce dual friction clutch, K&N cold air intake and cone filter by fender wall, Fibreglass mach1/ram air hood, posi system, 3.73 gears, B&M Ripper Shifter, BFG Radial T/A 235's on stock 15in rims, Flowmaster exhaust, H-Pipe, The car has been lowered 2inches with Eibach springs, and i'm looking at getting some MAC Equal length headers.

I just wanted to know about how much Rear Wheel Horsepower i might have (assuming i do add the headers) Anyone know? It would be greatly appreciated. Thanks.

well considering they come with about200 REAR wheel hp (at most) stock and 220 at the fly...and u've only added about 15 hp with the exhaust and intakes...ur prolly lookin at 240 at the fly and 215 at the wheels...if u wanna make ur car go fast, exhaust is deff a good place to start, but dont think its going to give you a bunch of horses...the gears and shifter are a nice touch...now look at saving up for some weld wheels and bolt ons or nitrous...<IMG src=smileys/smiley14.gif border="0">

I'm with Gunner on the est hp numbers, assuming your car is in good tune

My 91 had 206 at the rear tires with mac headers, OR H-pipe, flowmaster 40's, and 25% loss of compression on cyl #6.
