Hi Joe,you're right,the 79 Eldo uses the TH325,the TH425 was used on the earlier (1978&down) big blocks,the main reason i chose the 79 Cad. was the frame with the 350C.I. Olds eng.& TH325 trans.with all suspension is a perfect fit in the Cord bay which eliminates a ton of $$$ fabrication work.while it may not be much of a performer it'll be dependable and have enough power for highway driving. I do plan to make a few changes,like a good F.I. unit & ignition system.
Thanks for the reply Joe,warmest regards,Jerry
