TQ surges, tranny has no power...

Hey guys,
Finally got my Challenger (318, Performer intake, Thermoquad carb) running and took it out for a once around the block....when idling in the shop, it would idle OK at ~600rpm, then increase to 1200 for 10-15 secs. Then it would go back to normal idle. Mix screws set at 1.5 turns each....(from the 2.5 initial).

As well, when I put it in gear, it goes forward, but I can't get it to go fast!!! The rpm icreases, but the speed doesn't!! Just kinda idled it around the block, tried a few pumps and pulled it back in to figure it out....

Thanks much!

Bump...someone gotta have some opinions!

Ummm TQs are junk as you're finding out, and your trans is messed up.... That about sums it up .

Ahhh, wrong-o Coke-head kid....I've had TQ's that have run better, producing more HP than anything else out there!! Once they are tuned properly, they perform extremely well -but it's not for the tuner kid crowd, so you'd better stick with Holley!

If you want people around here to help you you need to curb the attitude. TQs either work real well or not at all. Your's sounds bad. Rebuild it or replace it. Have you bothered to check for vacuum leaks?

the post he got wasn't helpfull at all and more disturbing really, so I understand the reaction.

in another note:

I'm agree about some vacuum leak around. Check for that first

Tranny.... could converter get damaged ?
