Plymouth Duster Suspension/Tubbing Question - Drag Racing

dart_68 said
Sounds like a fun build and not too different from mine. A 10 second 340 car is entirely possible with or without NOS or other boosters. I doubt that it would be streetable without boosters, though. But if you're only drag racing then no worries.

A leaf spring suspension is quite usable. No need to go to coil over/4 link suspension unless you want to. What I WOULD recommend is a set of fully adjustable shocks front and rear.

Don't have an answer for your second question but I am in the same boat as you and am interested in an answer..

Thanks for the information! I was definitely planning on getting adjustable shocks for both front and rear. Just based off pictures of other 340 Dusters drag racing (some with the front end off the ground) I see they kept the leaf spring set up. I just wanted to get some advice from you all on here before spending the money and realizing coil over suspension was the way to go. But if I can get in the 10 second range with the leafs then I'll probably just stick with that.
