So, what do y'all think. Let's say after building this supercoupe engine it has 425lb/ft of torque. Wouldn't that grenade my T5 no matter what I do to it.
My 1959 Lincoln MEL 430 was rated 490 lbs-ft, we called it a "quarter-foot-ton". I ran a T-10 behind it in two different Falcons, first time a '64 I bought brand-new, second a '63 which had been a 6-banger.
Here's the '63:
The give-away is the fuel pump mounted atop the center of the timing chain cover, right behind the fan; all MEL engs. had it. Idea was, coolest place to prevent vapor lock. With stock C.I. Lincoln exhaust manifolds, this beast was something like 34" wide; move over 440 Chrysler!
Here's the same mill in the '64 Falcon. I bought it new almost a year before the Mustang was introduced, bought with 260 V-8, the 289 predecessor, and T-10 Warner 4-speed. That car did NOT come with a 9"; that I installed with the Lincoln. Had an 8.5" "baby 9" from factory. Peppy little car w/260, Chevy-eater with the 430. A nasty Mexican-National kid ran a 64 Chev. Bel-air "unbeatable" around our neck of the woods, I ran him from a 5mph "punch" out on County Line Road near Argonne National Laboratory, I think still McCook, Illinois, I looked over, he hunched like a maniac power shifting, I eased off each shift, every one just pulling ahead of his efforts with ease. I won TWO DOLLARS off those Mexicans! I figgered that T-10 just might bust.
Apologize for image "quality"; these pics were taken with a Polaroid "Swinger" camera, nearly 50 years ago.
