Jetaway swap?

[dallas6778]

hey all i have a 1969 cutlass with (or had) a jetaway which is pretty well dead. im gonna swap to either a th350 or a th400 but i cant decide which will be better. obviously the 400 is the better choice but im not sure how easy itll bolt in considering im low on cash. the one im looking at is from a '77 firebird. any information would help. thanks!

The TH350 was optional in the 69 Cutlass and will be a drop-in. The only difference from the Junkaway will be the kickdown cable. The cable for 69-72 runs through the firewall (the knockout is already there below the throttle cable) and is actuated by the accelerator pedal. You need a 69-72 TH350 pedal to accept the cable. Alternatively, you can use a later cable and bracket that goes to the carb lever. Everything else fits exactly.

The TH400 requires a shorter driveshaft, different front yoke, and different e-brake cables (due to the relocated crossmember).
