There were many kinds of performance options illustrated in THAT magazine. Most with big displacements.
Jim-R - ROTFL For Gen 2 Firebirds, the WS6 option - front and rear sway bars, four wheel disk brakes, 1 inch wider tires, beefed up suspension.
I’m not exactly sure, but I think there was a “67/68” Cougar that can be ordered with a aluminum or fiberglass front end and a 427 big block, I think a GX-7 ? Not sure. Also a “65” Mustang with a aluminum font end , 427/428 , I believe It was call a Cammer, it was white with blue racing strips down the center from front to back. I believe I read about them in a book, don’t know much else. But I do know they did offer such options as aluminum/fiberglass front end on some cars . Thanks
If it was early years for me it would be 1969 “S” code 429 Boss Mustang today for my tastes 2019 ZR1 Corvette either would sit in the garage till i hospitalized myself for bypass surgery i would want to be sure i would survive such a heart pounding experience,not to worry my piggy bank wont put a dent in the price of either.R
ZL1 1LE, overall winner for me but others I like are from Ford, Mopar, GM, AMC, Nissan, Toyota, BMW.
