Displacement Limits:
Forced Induction: 3.0L (OHC), 4.0L (pushrod)
Normally Aspriated: 6.0L
Rotary(all): 1.5L

Then there are weight limits... assume 2500lbs.

Engine block must be a production unit manufactured and badged the same as the origional standard or optional engine for that model.

I.E. Any block that wears a ford logo in my case (there's special cases for joint ventures -- like talon's which can use mitsu or chrysler engines because they were offered with both).


Is an aluminum 302 actually that light?

Any idea what a supercharged 3.8 weighs?
