is this Pontiac or Chevy 350

I'm looking at a Jeep. The owner says the motor/trans is out of a '92 or '98 Pontiac. First off it has a quadrajet on it. I checked the usual Chevy area driver's side rear for a casting ID and found 14010207. This works out as a '80-'85 Chevy 350 truck, 4-bolt.
There is also a 207 stamped on each side of the block just above the pan. The distributor appears to go through the intake - I read that Pontiac 350 distributors did not do that. I asked him to remove the dist cap (HEI) but he didn't want to do that - I think Pontiac dist spin ccw instead of cw - so I couldn't check. There is no block pad on the passenger side below the head. Did '80 - '85 Chevy 350 have that pad?

What do you think?

A Pont. has a separate timing chain case that bolts to the front of the engine. Bigger v-covers than SBC, a little smaller than a BBC, water x-over at the front of the intake is readily visible.

Dist. goes through intake, does rotate CCW. Heads have exhaust ports that point down at the ground, almost. Center pair of exh. ports have a head bolt running between them.

207 casting is 35o engine i have owned millions of these very common engine low power smogger crap

but can run good if in nice shape taken care of but that goes for any engine out there.


just google the casting number real easy.

mill the heads a little, put a better cam in, and good exhaust and a good intake ducting system and it iwll run really strong and efficiently

Of course it is. I'd claim a typo, fact is I wasn't paying attention. No more posting while CNN is on...
