Don't know motor size? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

GMC"ER · 07-20-2011, 11:40 PM

I just bought a 69 gmc stepside truck my first! The guy that I bought it from didn't know what engine it had in it all I know is it is a V8 with automatic trans.? I have looked online and still cannot find the size. The block number on the drivers side on the back side of the engine behind the drivers head is 3970010 I found a list and it gives a 327 and a 350 the same numbers? Also the number in front of the passenger side head is V0909CHH and 385117462. Does anybody know the numbers and what size engine I have? This is not the original motor it had a straight 6 in it originally but auto trans is original. Thanks for any help, Robert

pull the oil pan, if it's a 4 bolt it's a 350, if it's a 2 bolt it could be either

also if it has a stamp hencho de mexico from what I just found in search they are 350 mexico made 350's with 50/50 good/bad castings, I have the same block for my build, non mexico cast and I got lucky with the 4 bolt so it was a 350 and easy to source parts for

I would guess a 327, with the 462 double hump fuelie heads. Others will chime in.
