Mystery shudder
Don't know if this is a transmission or engine problem, so I am sorry if this is posted in the wrong group.
I have a 65 Dart, originally came with a slant 6 but I did a swap to a 340 I had laying in my garage from an earlier project.
So it is a 340 SB from a 73 Challenger, stock cam, Edelbrock AVS carb, Chrysler distributor with HEI ignition conversion, 904 Transmission with lockup (A999 I think it is called), it has B&M flex plate for external balancing and neutral TQ, standard stall. Lockard KD cable, B&M shift cable kit.
The car run great for few months, nice cruiser. But it developed this shudder at low speeds, under 40/50 mph. Above that you don't feel it anymore.
It idles great in Park and Neutral, no shudder when reving it like that. But once in gear it bogs and shudders.
I pulled down the the VB and did a TF-TC kit install that was supposed to fix the shudder. I added the "magic" lubeguard fluid.... nothing. But these were supposed to fix the lockup TQ shudder which happens at 45mph or so. My shudder is up to 45...
It may be an engine issue - too lean, the wires were triple checked for the correct order, don't know what else to do.
Hope I don't need a new TQ or transmission.
Any ideas?
