    I inherited a block that I believe is a Chevy. It has no side motor mounts, 2 bolt mains and the oil filter has a adapter that bolts onto the side of the block. Is this a '57 283 or 265? Maybe something else? The only casting numbers I found were 86133. Do any of you know? Thanks!

    Know I'm thinking it's not a chevy. It has 4 bolts around the cylinders. With only 10 bolts per side! On all the cylinders it has a very deep champfer that goes around 1/8 of the cylinder. Seems to me it would cause the head gasket to blow.On the intake it looks like it gets a pan gasket. The reason I say this is because it has 2 screw holes down the center of the valley and on the ends it is very rounded. It is also VERY open down the center of the valley and around the lifters. The dipstick goes in on passenger side and it looks like it slants forward alot by the angle of entry. I did find where there are motor mount bosses. There is only 2 per side and they parallel to the oil pan and very low. The motor is blue.Not for sure if it's original. The distributor sits in the rear. I also could not match the numbers on the website posted above. I had already looked there.

    I thought so. It sounds like a Pontiac. Are there any numbers cast in the lifter galley area? There's a date code by the distributor hole (4 digits; one letter, three numbers), there's also a two letter engine code stamped on the front of the block on the passenger side of the engine, just near where the cylinder head meets the block.

    In the lifter galley area there is no numbers. It is very open in there by the distributer the stamp reads 86133. On the front of the block on the passenger side of the engine there is a 4 digit number.

    Hmmm... Those don't sound like Pontiac numbers... Mayber a SB MoPar? I still can't access the link you've provided.
