Re: [Chevelle-list] 402 BB & TH350

[Clint Hooper]

1967 was the first year for TH400's to be available in Chevelles and El Caminos,Tom. A stock TH350 needs some beefing up to live a long life behind a BBC. The advantage to the 350 over a 400 is the lower rotational mass (less power drain) and shorter low gear; 2.54 vs 2.48.
