why a custom built converter isn't for everyone....
is that off the shelf or custom? Some companies have 3 street versions on the shelf. You call them and tell them your build and they pull "one off the shelf" that they think fits your build the best.
That’s custom. I just ordered two of the 9.5’s for close to the same application, but they weren’t the same.
One is a 340 with 3.23 gears and a Comp Thumper cam of some sort. And it’s not quite 10:1 compression. I can never remember which one he has but I have it written down...old age and all that. And he has the Air Gap intake.
The other is for a 340 with an MP 280 solid circle track cam, a measured 10.42:1 CR, 3.i0 gears and a Strip Dominator.
They are both 9.5 inch cases but they are not the same converter. I know the first one was a massive improvement over what he had because that one is in already and he is as happy as a pig in poop. Went from a car that was miserable to drive...undriveable really with an 11 inch converter to being a pleasure to drive with the PTC. He has already said he’d never do another car without a custom converter.
The other converter is out on my shelf. It’s going is a 73 Duster that belongs to my friend (both of these guys are very close friends) and I have the engine about ready to pull so I can drop the new engine in. Before that I need to go through the transmission, rebuild the front end and swap out the 7.25 for the 8.25 with sure grip he found.
Plus, I need to get my junker put back together and on the dyno, put my lathe back together, curve 3 distributors, tune 1 single 4 carb, two pairs of tunnel ram carbs, build the BX4 for the Duster and buy and build a second BX4 for me for my tunnel ram.
I’m going to be very busy.
