My adventure in putting a 1987 Thunderbird "Super Coupe" 3.8 S/C engine into a 1983 Mustang GLX. Some of you may ask WHY????? V8's are cheaper, yadda yadda,yadda. I have heard it all.Well it is like this; Everybody and their mother, girlfriend and their buddies have a cowl hooded, chrome wheeled V8 Mustang. Well peeps I will never cop to being normal...EVER! So I brought together all my available information about Mustang parts, colors, and with the help of some factory trained Master Ford Techs, I started to build my version:
Using a 1983 GLX I had bought in a package deal (3 Mustang ragtops 1983-1986, for $1250.00 ) I decided I wanted to see how much could be done with the ford V6. Starting with a 1989 engine , I stripped it down and had the engine sent to a machine shop for machining. I then bought a 4.2 Ford (F-150) crank, and forged rods, and forged Wiseco pistons from Super Six Motorsports ( www.supersixmotorsports.com) to bring my displacement to 4.3 Liters. The stock compression was 8.7 to 1, but to make a few more ponies, I opted for 9.5 to 1 since I am not going above stock boost levels.
The bottom end was modified with a Delk Performance main bearing girdle, with an ARP stud kit. The oilpan is a modified F-150 unit sculpted to work around my stock K member. The top-end uses a set of Stock S/C heads that have been ported, polished and blended. Bee-hive springs and valves with thinner stems so airflow is greater, and heavy-duty valve locks and a Comp Cam to help the beast make power.
The air intake system has been enhanced to remove restrictions inherent in the factory design. The main problem area was the "Blower Hat" that sits on the supercharger. This part required the air to be spit upward and forced to do a 90* turn in 1.3 inches. What I did to remove this problem waas to remove the inner fins and drill a 3 inch hole out of the top that will go into a tight 90* silicone tube then into a tube going to the intercooler, which is double the size of the stock intercooler.
The body features a 4 piece Cervini's LX kit, a Cervini's "Stormin' Norman hood(2.5 inch rise) and a Saleen wing. Painted in Sonic Blue with PPG Russet Prizmatique added to the color, it looks like a bass boat when you walk by it on a sunny day.
