Here's a short video of my Formula after my motor swap. It got a 383 LT1 with an Edelbrock performer air gap 58mm intake, hotcam and the bulletproof MSD optispark. Other upgrades are 410 rear gears with a detroit locker, SLP coated stainless headers with loudmouth 1 all the way back, Edelbrock adjustable coilovers, and a stage 3 clutch. I have owned this car for ten years, and the motor had about 170K miles on it before It lost oil pressure at idle, and blew a head gasket, but even with these problems, it was still drivable, and it still did great burnouts. I am going to build a 396 with the original motor.
