Overdrive tranny in an A-body

I would have to say why not?

A stock 5.2l magnum motor makes a bunch more power than a stock 318. I you plan to modify it the magnum 5.2 already has the best small block heads mopar delivered from the factory and it is already set up for a roller cam.

Compare the 18 to the mag and see the differences.... you are comparing a factory roller and higher compression mag to that of a 7.6 to 1 or 8.0 to 1 compression la 18 with a S M all pimple cam....

Just the exh port is better, and that is it..

So if you added a roller and made the compression equal..

The mag was a fix for mopar to lose the need for 2 heads on the same block..

If you were just say switching a low 7.6 to 1 18 for a newer mag and not interested in anything other then that, fine.... but if you're after performance.....lose that mag junk..
