Ok, I have build numerous cars and never had this problem. I'm building a 1971 Nova with a Blueprint 383 stroker - 2 piece rear seal, factory powerglide with Hughes PG25 torque converter, Pioneer 2 piece seal weighted flexplate with weight towards motor. I rebuilt the trans and installed a Sonnax front pump gear set. It is install correct with recess towards the converter. (spoke to Sonnax tech today and its correct. ****Converter is installed into all splines and engaged into pump tabs***. I can only get 7/8 clearance not 1"1/8 from converter mount tabs to trans bell housing face. The converter is almost rubbing the inside bell housing. The torque converter is snug, not pushing against the flexplate. I know it should have some space/clearance from flexplate to conv but I have removed everything three times to check and I don't see any errors in the install. Any one else run into this??? Please help me. Frustrated X10 Is there any difference with SCAT cranks, is this my issue?
