16 years ago in PONTIAC
Would like information on the '59 389 cu. in. 420A. I'm sure it wasn't the standard stock engine used in the Pontiacs of that year. Any info would be greatly appreciated.

A 345HP was the biggest available in 1959, both were tripower, 4bolt main, HD exhaust manifolds. Pontiac was really starting to rampup in 59...
A 420A 389 was not standard in the StarChief's, someone most likely custom ordered it. A rare find!! Do you have a block code you could post? This would help identify what it is. Is it a tripower engine?
