This engine was built by Randy Malik to be used in my 92 Mustang GT "street brawler". The heads were left over from my previous 472 and were nearly box stock.

FRPP 9 way Cam Gear and Chain
Comp Cams Stainless 1.73 rockers
Scat forged 4.145 stroke crank- massaged by Adney Brown
Scat 6.7" H beam rods
Canton ProPower Fox body pan w/girdle windage tray combo

I want to thank Randy Malik for building this engine for me. Randy spent alot of time answering my emails while we were planning this build. He is truly a wealth of information, and I thank him for taking the time to explain things to me. I also want to thank both Randy Malik and Vince Impastato for their help and expertise in breaking in, tuning and dynoing my engine. It was my first time on a dyno, and I found it to be well worth the expense and time. 8)
And to everyone else on the forum that have taken the time to answer my posts, THANKS for all the help! :D

Last minute thrash!

This was what my garage looked like after a 2 week thrash, trying to get my car back together before my vacation was up! This is about as messy as this garage has ever been. Unfortunately, my car still isn't running and the garage is still a mess. Hopefully I'll be able to solve my issues and get it on the road when I return home on vacation in August. This is my first attempt at posting a picture, so I hope it works!

My car is a street strip with a C-6 and 3.73 gears and a street friendly 3700 stall. Last time I had the car weighed it was 3175#, And I've taken some weight out of it since then. I used Feetfirst's build and drag strip results as a reference when we planned my combination. I was looking to go as close to 10.0 as I could without going faster than that since I only have a 6pt rollbar. Feetfirst got his combo into the 9's, I'd be happy if I can get 10.teens! Like Feetfirst, my engine also peaked early around 6100, and I may have to change rear gears to stay within my powerband at the top end.

Hugo: No results yet, I went back to my ship 6/1 and won't be getting off until 8/4 so the car is still sitting in my garage just as in the picture.. As soon as I get home, I'm going to try and move my engine back to the 1" setback holes in my crossmember in order to get some fan combo. My new crossmember is 1.5" lower than my old one and with the drop the angle changed and the water pump snout won't clear the fans! It looks like my headers will be real close but hopefully will fit. With the drop the header tubes are only about 2 3/4" off the ground which i don't like, I'm probably going to crank my coilovers up to get some more clearance. If not, I may have to look into getting someone build a new set of custom headers . I'll post as soon as I get it back on the road.

minimum 4800 stall.......
youd run a 4800 stall converter regularly on the street? wont that create a lot of heat?
I guess it depends what you call street driving.............i would drive mine without question 30-40 miles easy with a 5000 stall. Just need a good tranny cooler.............and some good mufflers :D

I finally got my 92 Mustang back on the road, see the following post.

I wanted to thank Randy Malik for building me such a supurb engine. I've been taking it rather easy on it so far, but I can tell it has alot more power than my old C-460 cammed A-429 headed 472. Randy came up with the right combination for the cam so that it has alot of power at top end and still is drivable on the street! I can't believe the throttle response this 502 has, it really sets you back in the seat. Eventually I'll get it to the strip and get you some numbers. But for now, I am just amazed at the response and power this engine puts out. Thanks for everything Randy, your the best!

sweet build Mr. Randy ..... did he ever run the car at the track ??
No. Like you Nick, I too have some traction issues to work out. Also, being unemployed for 8 months sort of puts a crimp on the budget!
