I always removed and installed my 440 in my 69 cuda with the engine and transmission together. Heck even did it without removing the hood. My car was an original M code car so the engine size wasn’t an option for me but at the time I also had a 69 340 Survivor. If I was building a car from scratch I’d go with a 360 with big valve 340 heads. I had a stock 79 Little Red Express with this combo and it was quick.
