I'm replacing a tired 360 with a 500 c.i. Cadillac and TH400 in a '70 F100. Is there anybody there who might have done a swap like this? I have questions about the oil pan needed (front, middle, or rear sump), steering box clearance, and probably a few other challenges.

I will use the nine inch rear end and the 3:25 gears that are already in it. Would that be a suitable choice?

If somebody has knowledge about such an installation, or one similar, I'd like to hear from him (or her). I need help staying out of trouble and I'm too old and cranky to appreciate surprises.

Thanks -
