The poly isolators hard, but they're not solid. They have some flex, and they will give. Yes, they're fine for 99% of applications but no, they're not as effective as the aluminum. With the aluminum (and the earlier Mopar/DC iron isolators), the frame rails are tied solidly together as close as you're going to get to the A/E/pre-'73 B-body setup. Ultimate handling, and high-torque applications pretty much require the solid isolators. I would consider them a must for an RB engine or a well-built 4" stroke small-block--particularly with a manual transmission.Why? They are awfully hard. Seems like it would depend in intended use, but wouldn't poly be just fine for most applications?
Yeah, poly would be fine unless you get truly silly with the 360 and back it up with either a 4-speed or something with a high-stall converter (I mean high, not 3,200RPM :icon_biggrin: ) and a transbrake. You'll give up a little on the autocross course, for sure, but if you were taking autocross really seriously you wouldn't be using an FMJ car in the first place!
