I'm kinda leaning towards a bigger TC too. I like a 2800 with that factory cam. But some of the 268* cams out there need more.
But I'm also all for a decent performance tune up.
But since you are gonna need an LSD anyway, I'm liking a TC and 3.55s.In this way 65mph is still doable, with those smaller tires probably kicking out around 3000 rpm .
So that comes to; a tune, an LSD/3.55s, and a TC; probably in that order.
If you have to choose between a TC and gears, I think I would pop for a 2800TC, AND an LSD, cuz tirespin will be an issue.
I think you are on the bottom rung of a ladder that will take you straight into Mopar Mania. It starts with these little things; you know; like a little more giddy-up. Then soon the tirespin gets old so more rubber, which needs bigger rims which leads to a narrowed rear and a spring relocation. Then the engine doesn't seem to be what it could be,so in goes a cam, which needs an intake, and of course that little carb has got to go. So now the tranny goes up in smoke, and the rad can no longer keep up, and the ignition won't pull at the top. Or wait, maybe the fuel system gives up first. In any case that tranny has got to be beefed up, and then; man! it sure could use a little more off the line punch,so out comes the engine and some new taller pistons go in, and things are moving along. But on the first track day you find out the engine is kindof flat on top, so off come the heads for headwork and, man! I just gotta have a bigger cam!. And that leads to a bigger rear end, a bigger carb, and a new TC.By now things are progressing and the track official comes over and says; "I'm sorry son but you are gonna have to put a cage in this beast before you can run here again."
And so the Mania continues..................
The ladder has no top.
But the climb can be a lotta fun. May it always be fun for you!
