B4 Engine Suffix Code?


Hello all,

I recently bought an a 1965 Chevy C10 truck, and a Chevy small block was under the hood.  It was a Frankenstein motor with a 1971 intake manifold, and 1973 heads.  The casting number on the back of the block is 3914678 which indicates it could be a 302, 327, or 350.  The info on the top right front of the head has a serial number of 781129468 and then V0I04B4.  From what I was able to gather, the motor is from a 1968 Pontiac based on the partial serial number.  The second set of characters I believe tell me that the motor was cast in Flint, Michigan on January 4th.  BUT, I cannot find what the engine suffix code of B4 stands for.  Can anyone help me out with this?

Regards,

Chris

Not that it's any help but you're not alone with this.

Based on the post that Carl linked having the same unknown B4 suffix in another Canadian Pontiac, cast in Flint,  maybe I'm stating the obvious when I say its a 327.

Neither A 302 or 350 was offered in a 1968 Pontiac.

I would agree that it would "most" likely be a 327 but the question would be horsepower and trans type. The suffix code should correlate to a given combination and that is what Chris and the other post were/are looking for.

You could get a 350 Astro Econoflame (295 hp) in the 1968 Pontiac Acadian with the SS option.

 They weren't built in Canada and its been established that the engine came from a car built in Canada.

 Sorry I was in a rush when I posted. In 1968 production shifted to Willow Run Michigan, prior to that they were built in Oshawa. The last Acadians were all built in Michigan 68-71 models.
