Sweet car. Lots of threads about this. Just the normal Mopar steering wheel slop. The borgeson box helps eliminate the slop but it’s around 1k for the kit. I have a PST 16:1 box in my 65 dart manual steering, little hard at low speeds.
I have Doug’s headers D453 for my small block 67 Belvedere. I bought a TTI 2.5 X pipe kit with using my own mufflers. I got the header adapter kit from TTI, it’s a real nice fit. Dustin.
A nice cast iron 4 barrel do the job. I swapped my cast iron 4 barrel for a LD4B and I really didn’t notice much difference overall on my 273 hipo engine.
Maybe time for another project car. I have the opposite issue in my life right now. Never bored not enough time. Got 2 step kids 13 and 9 and a daughter 7.
