Personally I wouldn't even mess with something that original. But, since you asked, nitrous is quick and easy. 😆

Seriously, if it's that original I'd probably leave it alone. However, if you're intent on hot-rodding it I'd suggest removing the original 340 and transmission and storing them along with the OE exhaust if it's still present. Find a cheap junkyard 360 and do the usual: compression, cam, carb. Headers, free-flowing dual exhaust and a 3.91 or 4.10 gear would round it out nicely, assuming you don't do much highway driving. If you do, I'd suggest something more along the lines of a 3.55, which the car may already have.

Don't set yourself up to grenade your numbers drivetrain. It'll break your heart and ding your value.

Welcome to the board! Have fun, both on the site and with your car.

The safest is to build a separate motor. And keep the original 340 wrapped and tight. A classic 408 stroker? With a rear gear upgrade will give to the street thrill I think you are hoping?

that sounds about what I may do, no permanent modifications!

Welcome to the site from Arkansas! I agree, keep the original motor in the corner and build a 408. Lots of torque and fun for the street... or track should choose.

How come some 73's have them God awful bumper guards. And some don't? Or did folks just replace with a 71 style bumper? I noticed many liked the using the '71 style grill?

The Feds mandated 5 M.P.H. bumpers for the model year 1973. Instead of remodeling the car, they just adapted by using big chunks of metal & plastic..😀

I remember. Or should I say? I remember the commercials. Bumpers that would give a little at very slow speed impacts. That was Plymouth's solution? Oh for God's sake! I'm sure that has been the topic of discussion here on e-bodies.

Welcome !
I agree with building a 408 using a 360 block , put a shift kit in the trans if it si an auto & keep the original engine untouched .
