does any one have any experience with ATF.
they remanufacture transmissions and sell torque eonverters.
how would a 12" with a stall rating of 2200-2800 torque converter work with a tpi with ported edelbrock base,tpis semi-siamised runners,ported plenum, and 52mm throttle body.
what cam would you suggest for the above combo.
this is a daily driver.

 

For a stock cam that TC is too big for a TPI. Its over your peak torque. A ZZ9 and 1.6 ratio rockers would kick with this converter if the heads could flow the number. Stock heads will need mods with this setup and the machine work and parts might not be worth putting into them (Good valve job, porting, machine down the valve guide, machine the spring pocket {Although there's some 1.25" springs that K-Motion sells that work with this combo, you will need +.050 retainers ($30) and the springs ($120) tap the studs and get screw ins ($30)... I went this route because the guy I bought my car off of had the heads ported by Morgantini racing and equiped with positive valve seals ($600) so I threw in the rest, otherwise it is definatly worth every penny getting AFR190's.

The above combo (AFR's, ZZ9, 1.6RR, Simesed runners [might want to cut them down even further] and 52mm} with the above TC would run dam strong.

Just my .02
GoodLuck

 

A TC with a stall between 2200 and 2800 isn't that high. TC's don't become a driveability issue unless the stall is 3000+. I wish I had gone with more stall on my 305 TPI.. 2500 would be nice.

And how would a TC in this range be over peak torque? Peak torque shouldn't occur until over 3000RPM.

I just ordered a 2800 Vigilante with stock cam and heads as this is what PI recommended. They absolutely assured me this is not too much stall for my car.

Bob is right here. The Precision/Vigilante is without question the best way to go. I've been through many torque converters and believe me when I say 'do not skimp money on a converter'. It's not worth any savings in the long run and you're likely to have little performance increase along with some drivability issues.
The Vigilante is the way to go for best performance and no problems. I had doubts before I paid all that money for it, but now feel it was definately worth the money.
As far as a camshaft, I say try out a hydraulic-roller from Lingenfelter Performance part # 74216
It is a very mild mannered but extremely powerful cam. I run it in my 383 and have no plans at all to ever get rid of it. It will be perfect well into the 9 second range and acts very similar to a stock TPI cam.
The camshaft is THE major player when it comes to drivability, economy, and emissions.
my advice,
good luck

Hey I know it's not a third gen but i drag a 1967 dart started with a 3000 stall then went to a 5000 stall and went from 10.78 to 9.13 quick. I also did some jet work at the same time so I don't know exactly what the tc did but the 440 launches now. yea I know mopar #^^#$
