i have an 86 chevy 1/2 ton 2wd. i put an 71 chevy 350 engine,with a 87 chevy 700r4 tranny. the engine and the tranny lined up fine. when i tried to bolt the fly wheel to the torque converter there was an 1/2 inch gap between the 2. the engine and the tranny are bolted flush i tried longer bolts to pull them togeather,all that did was unseat the converter. causing leaks. could it be that i need a difrent wider converter.  plz help

Are you trying to re-use the Turbo 350 torque converter or did you get a 700R-4 to go with your trans?

Where did you buy the transmission and TQ what do they have to say about it? Did measure and compare dimensions?

I just got off the phone with Carl Rossler of Rossler Transmissions, talking about this gap problem, because I'm experiencing it also. He said to unbolt the converter from the flexpate and slide the converter back into the trans.  Hold a 3/16" drillbit to the face of the converter pad and measure the remaining gap, and use equal thickness washers or spacer sleeves to make up the amount of gap. You should not pull the converter forward more than 3/16 to make contact with the flexplate or spacers in this particular situation. You also have to make sure that the center stub of the converter is not pulled out of the end of the crank. Hopes this helps you out. Also hope you didn't ruin your front pump by having the converter pulled too far out.

Smurf,

Thanks for jumping in on this. Do you still have a question about headers? Call my cell if so.
