ok i found my issue.....well one of em haha so my engine was a manual trans prior to my swap and it had the pilot bearing installed preventing me from figuring out the spacer bushing piece with the 399754 TCI flywheel simple mistake haha and for the th350 trans i used first i simply bought a 6.0L flywheel and gm adaptor piece/bolts from the junkyard and ovaled out 3 torque converter holes so it would bolt up and she worked fine. the 6.0 L engine must have a 4l80 trans behind it for it to be the right flywheel for this.
so i now have the flywheel bolted up (399754) the flywheel simply bolts up as normal the torque converter centering ring/bushing slides into the end of the crank freely before or after bolting up flywheel (did not have to hammer it into seat) and the torque converter snout fits snugly into that. the trans and stall torque converter to flywheel are going to mate up perfectly (measured) but when i tested the converter alone to see how far the snout penetrated the bushing it was not fully seated into it thus leaving approx 1/8" or more space where the bushing could walk outwards onto the TC. snout and that creates a situation where it wouldn't be penetrated into the crank enough anymore to keep the TC. perfectly centered.. not good
so is this what you mean by "ring welded to TC.?" i think if i had a ring spacer to put on the converter snout prior to close this 1/8" or more gap it would work great or weld it to the TC. or weld it to the centering Bushing
part numbers for spacer rings??
what ya think? any extra info appreciated thx.
