I finally got the engine and exhaust all installed. Transmission is a TH700R4. From everything I've been reading online, tweaking that transmission is a royal pain in the butt. I picked up a new TV cable kit that automatically adjusts the TV cable from the carb to the transmission. Once the engine & transmission were installed, I dropped the transmission pan, swapped out the TV cable spring, installed a new filter, and re-assembled the transmission.
The exhaust was then bolted on, transmission fluid filled, and a test fire commenced. Once we verifed the engine would turn over and fire, we connected the radiator for a full on test.
