Anyone have an opinion on what motor this might be? It is in a repo and no real info on it. Thanks.

Big block chevy!

If you buy it, one of the things you would want to do is to move the hose off the top of the water supply to the exhaust manifold bottoms.
Instant vapor lock possibility!

Need to loosen the forward carb fitting and rotate it up.

[fogducker III]

With those tall valve covers might be roller...?

[DonziJon]

The exhaust Maiifolds and Elbows are Stock cast iron Mercruiser, on a small block Chevy 350. I just replaced mine last fall. John

I think that is at least a Gen V big block with maybe a bravo.....looks like a mech fuel pump on the sea pump and possibly stock cast iron big block manifolds because the risers are more towards one end of the lower on each of them...most risers on sbc are centered on the lowers.

However, those valve covers seem kind of small for bbc, but it could just be the picture and i'm sure Fix is probably right.

look at the timing cover,if its a metal cover its a genv motor (flat tappet cam )if its cast alumimum its a gen VI (roller cam)

YUP. I think you're right. The elbows ARE off center on the manifolds. Small block manifolds are interchangable from left side of the motor to the right. John

same with a bbc:) their just offset..also looking at the intake it couls be a 502? looks like a team g to me,465hp or a 500hp painted black or just could be a 454.gen V will have a 8.2 on the side of the block..the only way to really tell is the casting #'s on the back of the block..

i wouldn't think its to radical bt the exhaust manifolds and it exiting a ypipe.

another photo that is a bit clearer.........

They are now claiming BBC 496 but I am trying to get some tag numbers :crossfing:

port side rear of block above bell housing app 11 o clock is where the #'s are..could be a 454 stroker motor..still hard to see the timing cover with it being all black..

[BUIZILLA]

i'm thinking GenV with that fuel/water pump carryover setup....

[Greg Guimond]

1006 286 GM are the numbers on the block in the back

[Greg Guimond]

check that ........10069286

454 (4 bolt) 1990-91 , IV short deck

Now saying it might have a roller top end and aluminum heads. At least I have a rough age. Thanks for the feedback.

[Greg Guimond]

I'd rather not say for the moment for fear of a lurker snapping it up before I can figure things out.
