What's the weak link in my 440 build?

I’ve got the Mopar Performance replacement springs and I’m planning on putting caltracks on. Hopefully that set up will work for me. If needed I’ll switch to the caltrack mono leaf springs. Mini-tub and spring relocation are happening as soon as I get back as well. I’ve got the 11” wide wheels on now but they stick out about an inch.

The 4 speed is a 1:1 ratio final drive. I have an aluminum overdrive 4 speed as well but it won’t handle the abuse from what I’ve been told. I’d really like to get a gear vendor overdrive but I’ve got other priorities on the car first.

I cut a ton of metal out of the bumpers and removed those huge bumper shock absorbers as well. Once I can find some aluminum bumper brackets I’ll be able to remove the last few pounds. I like the look of the chrome bumper so I’ll keep those but all the steel behind them has been removed. I’m hoping I’m lighter than 3300# but I figure that’s a safe estimate. Had it weighed a few years and it came in at 3450 without driver and full tank of gas. This was before cutting any weight out and I think the scale was a touch on the heavy side.

I’ve got big block torsion bars installed but still have the slant six bars so I’ll be putting them back in. I’m also considering removing the sway bar but I’ll have to see how this affects it on the street. As for the doors I’m hoping to find a usable set and go to town with a hole saw (see photo below). I can remove the crash bars if they’re the later doors and AAR sells a fiberglass door skin for $130 that would save a few pounds.



Overall, it sounds like I’m on the right track I guess. I’ve been trying to figure all this out as I go. I appreciate all the advice.

Yeah, it sounds like you're well on your way, go take the beauty to the track & get a baseline, run it as hard as you feel comfortable. I've heard mono leafs are the best but alot of folks like the super stock spring and level there car out by the d/s torsion bar. Good luck & thank you again for your service
