Firewall/floor clearence

I am installing a new firewall and floor in my 31 Model A. The engine is a 302 Ford and a AOD Trans. How much engine/trans clearance should I plan on? How much will this engine move under acceleration?

Amount of movement will depend on what type/material mounts you use. Solid, OEM Rubber, Poly etc.. Don't use a Solid mount on the Trans ever. Allow for space for installing/removing Bell Housing bolts. I'm sure someone who's done this type of Rod will chime in.

I like to allow at least 1 inch and prefer and inch and a half.



I have found that 1.5 inches works BETTER ... not only for clearance but for cooling the engine. If you get the firewall and floor too close ... the HOT AIR cannot escape out. Then the engine wants to overheat ... the floor stays too hot ( even at normal operating temps ) and things go down hill

One additional thought is to be sure to allow enough room to access fasteners as needed for maintenance. We've all cussed factory engineers for this, so don't make their mistakes.

Motor mounts should not move much. The trans mount is OEM type. I will try to find 1 1/2 inch overall. I will make the trans hump cover removable to allow for service.
