Mach One, that's the beauty of this forum. There are cars from 250 6cyl's right on up to the 429's including at least one Boss 429 I know of. Some are the same as the day they left the assembly plant, some are Gold Card level Concours, others are heavily modded, and some are drivers with personal touches such as yours. Everyone here feels like it's your car, do what pleases you. The only thing that would probably raise a few eyebrows would be talk of Chevrolet power in a Ford. I doubt you would receive a warm welcome and big sloppy kisses if you went to a Camaro forum and starting talking about Ford power in a Z28! Lol
If I was crusin' in a J code I sure wouldn't care what anyone thought. Enjoy that Bad Boy!!
