Could someone tell me the difference in the 351M/400 bell housing and the 429/460 bell housing. I think they are different lengths from front to back but dont know the measurements. I found a bell housing for my 360 > 460 engine swap. The wrecking yard guy says it is for a 460. I wish to use the stock 460 clutch and pressure plate and flywheel if I can so it matters to me if it is actually a 460. Please post measurements or ID #'s or something I can use.
Thanks, Tim

 

What are you doing swapping a 400 in place of a 460? What kind of truck?
