I haven't driven the '69 yet - just started it and ran it in the garage. Most likely need to replace the fuel tank and fuel line.My question is: will a bad torque converter cause an engine to stall when you drop the transmission into gear? Got a pretty good muscle car guy - even if he is into Corvettes - that says that is most likely what is going on. Idling above 1,000 RPMs, drop into forward gear and it just dies. ------------------

This is just exactly what happened to my car and yes you need to get at least a torque converter of 2200 to 2400 RPM instead of the stock one. Went through a few hair removals before I found this.------------------

The converter I have is one that is supposed to have been to match the motor and AOD. Got the AOD through the same guy. Stall is supposed to be 2,500 rpm.------------------

I didn't have the final tune set yet. Will be down to the 750-800 range - or whatever idle is supposed to be.------------------

I was just wondering if 2200 to 2400 isn?t kind of a high stall for a stock motor?? Or do you have performance motors? I was going to put a C4 with a 2200 stall in my 302 performer motor and I thought it was a bit high for street use, but after reading this post I guess I am right on the money.

I know you need to be able to put it in drive for idle speed but I'd get everything else checked out. I'm thinking it has a vacuum leak. Put a vacuum gauge on it and see what happens.

Is you converter a lock up unit? I had one on a friend of mines brand X car that started stalling when she stopped, come to find out the converter was staying locked due to a bad solenoid.------------------

Ronnie,I didn't specify, just went with what the tranny guy recommended. No solenoids or electrical hooked to it. ------------------

FoMoCo lock up converters do not use a solenoid.
They have a lock up clutch that relies on pressure in OD only. ------------------
