69 Dart Hard to Start When Hot, Starts Fine Cold. Vapor Lock?

wow I must have really bad luck if that old b van even thought about snow it got stuck
was that an 80s van?
My brother had one of those with a 360 auto in it that ran like crap. He brought it to me, and told me about all the mechanics that had worked on it and nobody could make it any better. Well long story short, he made me a deal I couldn't refuse, Oh boy.
So
I went to check the timing on this pig and could not find a mark. Finally I put the crank up at TDC #1 compression, pulled the doghouse, drilled a window in the BH, and center-punched the convertor, then inked it all up. Then the dial-back told the tale, what a POS that distributor was. So I fixed that and it still ran like crap, just not as crappy as before. So I pulled that big 2bbl off the intake, and started drilling everything in sight. IDK how many time I pulled that stinking carb off, she was sooooo lean.
Finally, she was running not too bad, but none too good either, so I started giving her more and more timing, and she started to perk up. So I pulled the VA out, and started sawing at the tabs to get closer to the timing she wanted.
Eventually, I thought she was running pretty good so called up my brother.
Well, I can't begin to tell you how happy my brother was. And the beast even got waaaay better fuel economy. My brother paid me a ridiculous amount of money for that job, but before too many months went by, he called me and noted that he was coming up on breaking even with the fuel-economy savings, and the power increase together with the better driveability, was a well-appreciated bonus. sand yes, he was a very happy brother.
BUT
I'm never gonna work on another one of those (I think it was a Holly) carbs. Next time, if there is one, I'm just gonna put a 4bbl on it.

How it was in the snow, I never asked. but I noticed that the tires were always newer, and it mustahad a pretty good alignment cuz the tires always looked pretty decent. and a good alignment especially in the winter, is crucial. And no, those tires were not 8-plys lol. I think they were P-types, which is 2+2.

So what is your opinion on that old Chrysler TBI ? I've never had one, and ain't planing on getting one either, lol. I have no opinion on those.
