When changing small block to big block are the towers different?
And do they need to be moved on the frame up or back?

I have 72 mounts that I'm going to use. What pump do I use long or short and what the differance , besides one being longer.

So it doesn't matter if the towers are placed in the front holes or back holes.? The motor will fit and clear front to back?
