i prefer formula's over transam's, namely due to the fact that I simply love the dual air scoop design and the package all together.
HOWEVER, It's a VERY close call, I DO adore t/a's , BUT only if it has an engine that makes it worthy over a formy, a RA4 t/a in cameo white will do fine, but then again, a formula 455 will win it again. A 455 H.O. T/A OR a '73 455 SD are on the top list. But then again, a 73 Formula with ALL available options and a 455 SD.....Is hard to beat.
Exteriorwise, it doesn't really make a huge difference. Both cars appeal in different ways. I LOVE the extreme, over-the-top race scheme that 70-72 transams have, in cameo white with blue stripe (the lucy blue with white stripe is amazing too), honeycombs, spoilers, fender extractors, etc. With a red or blue interior.....killer looks. It screams so much power and race....
On the other hand, I adore the finesse and almost italian design that the formula has. I have NEVER seen a hood more gracious and beautiful then a formy hood. Especially, since they WORK. All the round lines line up so well, I think without a spoiler the lines are even better pronounced. I enjoy a spoiler, but I takes away the 'hip' lines the car so beautifully enhances.....A dark exterior (black/very dark blue/dark red), with either a custom black or saddle/tan custom interior, again, with every option imaginable (rear seat console f.e.), and a beautifull set of Rallye 2's with the chrome outer ring, and the red PMD center cap, makes a breathtaking ride....
I'd take BOTH. no doubt.....If it were a 3rd or 4th gen, it would only be the t/a. if it would be a 1st gen, only the firebird 400. 2nd gen....Both.
So actually, I couldn't make a choise. But I wouldn't mind either one, as both do
I couldn't choose both above.....I'd guess it be the formula in the end though XD
