62 lancer hopefull engine swap. need info.

You should probably post in the Early A-Bodies forum -- they would be likely to know the answers.

I can say that yes, a small block V8 should fit, I just don't know what the motor mount situation is. That heater box might be an issue, too. You'd need a V8 transmission. A 904 is fine, though, at least up to 400hp with the right internals.

so a slant six 904 and a 904 off a v8 engine are different because they have different guts? i appologise for my ignorance here. new to this. trying to suck it all up.
