My neighbor brought home an engine he says is out of out of an old 2 ton truck. Pass side rear has the captain bars, so I assume it's a 261. The number by the distributor is F9I8L. If some one could tell me what this is, then I can pass the information on to him.

TIA. Brian

The F preface and L suffix on an engine serial number were used in several years, starting in 1957.

In 1958 (and other years) it indicated a 6000 series truck standard engine - the 261 was the standard 6000 engine in 1958.

Here are locations for all the codes that would allow a better identification.

Look for the other set of captains bars on the driver's side to confirm that is a 261. If not, you have a 53 235 originally from a car with powerglide transmission. Not a shabby engine at all, BTW. Full pressure oil, insert rod bearings, aluminum pistons, hydraulic lifters. All you need is an 848 head from a 56 or later 235 and you have all the power that a stock truck needs.

What 261s had captain bars on the left? I have a '54 261 with only one set.

The Captains bars on the left side are not really visible with the manifold on. They are in the center almost at the top of the block. Picture


See the USA in your vintage Chevrolet!
