More questions from a newbie!
My project is a 1935 Olds sedan that been sliced and diced with a 47 Ford PU to make a transport truck for my son's race go-kart. The donor power plant came from a 1984 Canadian Buick Regal (305 SBC with a TH250 tranny) I have rebuilt 305 SBC, added a 240H CompCam and 1980 Camaro diff. with a 2.56 ratio. I've dumped the 250 and installed a TH350 from a late 70's Chev wagon.
Here's my concern: The TH250 torque converter had female threaded studs to accept bolts attaching it to the flex plate whereas the TH350 has mounting brackets with open holes. It would appear the TH350 requires both bolts and nuts whereas the TH250 had bolts only.
I checked but unfortunately the TH250 torque converter will not interchange with the TH350.
Do I require special bolts and nut for this application or can I purchase bolts from the local hardware store?
Afterward do I secure with the bolts and nuts with Locktite?
Lastly: With the tranny attached to the engine, the TH350 torque converter is about 3/8s of an inch away from the flex-plate mounting brackets. Should I install spacers (washers) to fill the most of the gap between the torque converter and the flex-plate or do I draw the torque converter towards the flex-plate using the bolts without adding washers? To me it seem to be too big a distance for the converter to travel.
I look forward to you help.
