Engine ID help?

[Xplantdad]

A friend of mine has a 56 Chevy and has a big block Chevy in it. He was told that it was a 454 but the air cleaner has 427 Turbo jet on it ( I saw the car briefly while I was in SoCal). I told him to get the "numbers" of of the front pad and that someone here could probably help on the ID.

So here goes...

Front: T0520CXS 14Z473787 (he said that the Z could be an S or a 5?)

Back driver side: 3999289

So what does he have under the hood? Can you tell what year, HP rating, what it was installed in originally? 2 or 4 bolt mains?

Thanks for any help http://www.yenko.net/ubbthreads/images/graemlins/beers.gif http://www.yenko.net/ubbthreads/images/graemlins/youguysrock.gif

Looks like a 74 454 2 Bolt, out of a Chevelle or Monte Carlo.

Those are very good builder motors. "289s"will take a 125 overbore. And they are very tough.

Thanks Ken. The 56 it's in has a turbo 400 and probably 3:73's out back...It's a fun car to drive... http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif
