Doesn't the DB mean 283 or 307? I hope not, but that's what it looked like to me....
It's an old engine, no screw on oil filter (has the old style case bolted in the center).. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | So what's the matter with a 283? | | | | | Joined: Feb 2006 Posts: 549 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 549 | not much wrong with a 283, except i thought it was a 327 and preferred that...
now, it doesn't matter much, just want to know what i have.. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | sounds likely to be a 283, and in a 58 it just might be original - a 327 is just an 'overstressed' 283 and more finiky - the 283 will last longer, and can be built to be as fast as a 327
did you get the numbers off the block behind the head on the drivers side? [on flywheel flange - if it's in the truck use a mirror]
327=
[62-64]3782870, 3789817, 3852174
[65-67]3782870, 3789817, 3858174, 3892657
[68-69]3914660, 3914678, 3932386, 3955618
if it's outta the truck the crankshaft flange can indicate pre or post 68, and I think that at least the early 327's still had the filter can, maybe all of them
the number at the back will tell you

In '68, that suffix was used for a 307 car/El Camino engine. I don't think DB was used after '68.

I'll get a mirror and check the back tonight ...tried before I posted but couldn't get my old [censored] bent enough  | | | | | Joined: Dec 2004 Posts: 452 Member | | Member Joined: Dec 2004 Posts: 452 | I have to revise and clarify what I posted above.
From actual Chevy parts manuals and the "Catalog of Chevy Truck ID Numbers", the DB suffix was used for the '58-'61 passenger car 283 with powerglide and 4 bbl. carb. That suffix doesn't show up again until '65, where it designated a 2 bbl. 283 backed by a 4-speed used in the Chevelle/El Camino. DB continued thru '67 for the Chevelle/Camino 283, and in '68 designated the 2 bbl. 307 used in the Chevelle/Camino.
Regardless, with the DB being used for the 307 for one year only, chances are good it's a 283.
