Modified Mustangs & Fords
1966 Ford Mustang Fastback R-Model Clone - Best Laid Plans
This R-model clone took a right turn when it met Gateway Classic Mustangs
"The car handles the same at 90 mph as it does at 60. It handles very well, and you don’t feel any crosswind; it just sticks to the road. I got the look I wanted--the early Shelby looks--with the performance and handling of today," Steve commented.
Steve’s Porsche mechanic offered to build the stroker engine for the Mustang, but the machinist didn’t follow the builder’s specs, and as such, the engine had issues right from the start. GCM fought the issue for a while, and with Steve’s blessing, opted to pull the engine and start over. It kept the Dart block and Scat reciprocating assembly and started anew with Roush parts. Since GCM usually builds its cars with Roush crate engines, it built Steve’s replacement 347 with crate-spec parts--parts GCM knew would work and make good power. The 347 was topped off with Roush CNC-ported AFR cylinder heads, a Roush-spec roller cam, and a full ACCEL DFI Gen 7 fuel injection system with Roush calibration.
"It was an expensive mistake and I don’t blame my Porsche mechanic. I’d take any of my Porsches to him in a heartbeat, and hold no ill will," Steve tells us.
While GCM was wrapping up Steve’s Mustang and getting it ready for its debut (the Mustang has been to SEMA and all of the major anniversary Mustang shows, MCA nationals, and others), he found out his car pal Wayne had been diagnosed with cancer. Even though his own Mustang was finished and ready for him to enjoy, Steve banded together with several friends to see to it that Wayne’s ’37 Ford five-window coupe would be finished in time for the annual Street Rod Nationals in Kentucky.
Through the two-month thrash, Wayne did his treatments, while his friends put his car back together and saw to it that Wayne could drive his own car through the front gates at the Kentucky Expo Center. Sadly, Wayne passed shortly before he could see his friend’s Mustang on these pages. "Wayne knew everyone in town and helped me locate parts and sources for my Mustang build," Steve explained.
Steve hasn’t had too much time to drive it since he’s not retired yet (there are some more of those best laid plans). But he stops in to the GCM shop and visits from time to time to see what the guys are building next.
"I really like their Bullitt Mustang they’re building now. If I ever sell my ’66, I think I want them to build me one of those." There are more of Steve’s best laid plans in action. Only time will tell if they work out again for this car enthusiast.
