OK 400 block,scat 3.75 stroke rotating assembly. This is a street car so just drove it to some shows and it started a rear mail seal after 300 miles did not think nothing to much easy fix right....wrong dropped the pan and found metal checked some and seen the thrust bearing,I assembled the motor but checked everything during assembly even crank end play. Took it to the machine shop let him tear it apart found that crankshaft had been pushing forward.Check converter clearance and thickness check out fine.
Now I find out if the cooler does not have enough flow it can push the crank forward has anyone seen this on a 727 I know TH400 will do this, Got a Hughes 3000 converter and a Coan reverse manual valve body thanks for any input. Thanks Randy
