cam timing does this mean chain or timing gears are bad,or just rebuild the motor this fall,thanks for all your help,tim
If original timing componants, and high milage, good chance the timing chain slipped. Mopar used a nylon upper timing sprocket, it was supposed to run quiet, but they all fail. Just something to look at. You can tell if lots of "slop" in timing chain, just pop off the dist. cap, move crank back and forth a little, if Dist. rotor does not move in unison with crank, then lots of slop. MT

I missed the TC stall in my last post. Sorry.
Well your combo is off. I'd like to say way off. But that might scare you.Firstly,The cam and the cylinder pressure are quite a mismatch. And secondly the cam and the TC are also quite a mismatch.And then theres those 3.55s. Add to that the possibility that the cam timing may be off, and it all adds up to disappointment.
Going back to post12 you said;",I do have 355 gears and just do the small shows we dont race,just cruise". If thats true,then theres an easy fix. Pull that "race cam" outta there.(To properly make use of that cam, you would need to spend a ton of money.) Go back several sizes. Forget about the race-cam sound, its killing your combo.
You need a cam that will pull up your cylinder pressure,and will work with that 2400 TC and the 3.55s. You need a cam that will get you around 165psi or better,( since you're not racing) cylinder pressure.Without knowing your total combustion chamber volume, I cant advise you on a cam selection, other than to say, call the cam people.
If I had to guess, I'd say something around 4 cam sizes less. That would put you around 20 to 25 degrees less intake duration. So, 267*. Theres lots of good street cams in that neighborhood.It is a guess. A cam of this size will play well with the current TC and the 3.55s. For you, if you have the option,I think a wider than 110*LDA would be a good thing.

Even if everything was dead on. a 2400RPM convertor is way too tight for that combo.

How many is too many?
I had an ignition coil go bad once. It didn't completely fail but the secondary voltage was so low that the weak spark required a lot of timing to rum worth a darn.
