Clutch recommendations for 500+ torque 383

Brace your firewall because it WILL flex. Also brace your engine so it cannot shift toward or back. Start easy and work up to that Banzai run.

Is there a company that makes firewall supports for a 68 Dart? Also with the engine, would solid motor mounts be sufficient? I read somewhere if you use them you should use a poly trans mount?

Thanks for all the help
