To Buy or Not To Buy...
One of my good friends is moving to Hawaii and he can't take his mustang with him. Its a black 1990 Mustang GT with power convt. top. He bought a brand new 5.0L 302 crate motor and had it stroked to a 5.4L 331. The motor and 5-speed tranny have about 250 miles on it. The motor was done up right and is built by a very good and known mustang tuner here in MI and installed by my friend, his father, and I. After a dyno tune we estimate 475whp and 500 ft. lbs of torque. Has the 5 lug conversion with 03 cobra rims. 03 cobra interior. Full exhaust from headers back. His father bought it new in 91 so I know the history of the car and helped work on it with him, no accidents or any damage. Paint is a 8 out of 10, interior is a 9 out of 10. Pretty much everything is new except the paint and has over $18,000 in receipts. He has it listed for $8,000 but said he would let it go to me for $6,500. I've always wanted one of these early 90's mustangs but wanted a corvette more. Now I have a chance to purchase a very powerful one that I know the complete history of. So what do you guys think.. should I purchase or pass?

yea its a lot of car for the money for sure. I think we are over estimating the hp and torque numbers a little but nontheless a powerful car. I already bought the vette a few years ago and now i have a chance for a powerful early 90's mustang. I think I'll jump on it.

Sounds like a sweet deal...
I would be all over that car!
HP numbers seem very high with no power adders
Especially if thats to the rear wheels?...
My FRPP 347ci z headed crate engine is rated at 450hp fwhp.
On the dyno it put down 382RWHP which I was very pleased with as this equates to just over 15% parasitic loss.

yea, i think we over estimated the numbers. I think it will make 375-425rwhp based on other people's 331's that we collaborated with to build this 331 and other engine factors. Based on the average 15% loss from crank to wheels, crank hp is estimated at 440-500. Will know for sure if I buy it and then dyno it

i'd buy it. those things are getting hard to find with clean straight bodies. I couldnt see the pics, but it seems good to me. You can make those really fast with not too much cash (compared to vettes of course)
