Actually, the fire was at the Hydramatic plant. That's why you see some '53-'54 Oldsmobiles, Pontiacs, and Cadillacs with Dynaflow(Olds and Cad) or Powerglide (Pontiac) transmissions.
GMCs used the Olds V8 in the same applications that Chevy used the Buick. I beleive it was a 371, but the 394 may have also been used in the '58/'59s.
