The old gas is prolly too weak to fire cold. Better drain that stuff

Assuming it has a 4 barrel carb, and also assuming that 4 barrel carb
is a Holley.

A Rochester Quadrajet only has one float bowl, and a Carter AFB
(unlikely on a Suburban) has 2 floats, but not Primary and secondary
from my recollection (left and right, not front and back) Same with
AVS and Thermoquad.

Stock, the "burban would have most likely been a 283 2bbl or a 230
six, with a possibility of a 292 six or a 327 V8. The 327 would have
been a 2bbl or 4bbl Rochester, as Holley was not used OEM untill about
'67 (on the Camaro Zapper)

I know, there is a good chance it is no longer stock, and even a
reasonable chance it has a Holley 4 pot on it, but that has not been
stated, so the "secondary float bowl" is pure conjecture, and a long
shot.

According to the information I found, a stock Chevy 'burban in 63 would
have come with a straight six or a 283 with a 2bbl. By the block
numbers this is a 327 'high performance' engine from the same era, with
the non-spread-bore Rochester 4bbl that was used before the Q-jet.

I suspect that the former owner (who was _convinced_ that he was a
mechanical genius) put the engine in -- it was cleverly conceived, but
poorly executed; I had to make a throttle arm to get it working really
right, and at the moment it's one of those "big wad of grease with a fan
and carburettor" engines.

At this point if I can get back to a program of warming things up and
driving it around the driveway three times a year, I'll be happy.

Here's a picture of the truck, sitting in a driveway that hasn't been
mine for nearly 10 years. The driver then got to go for a (20 foot)
ride in it yesterday, and thought it was kewl.

Nice 'burb. That 327 HiPo should make it move along right smart when
all fixed up.
