305-E V6 value

[68GMCCustom]

I have an excellent running 305-E with the Stromberg 2bbl in my '67 GMC that will be removed soon. I've already been asked about it, so I am trying to determine a value. My feeling is that it had a valve job or possibly a complete rebuild when the truck was restored in 2003, though I haven't found the reciepts yet to verify it. It doesn't smoke, even on startup but it does use or "leak" oil. Mostly from the rear of the valve covers I think. It makes wonderful torque and gets excellent fuel economy...over 20mpg I'm guessing. It has the original 3 speed but my guess is those are worth $50 or so.

What would be the value of a complete, excellent running 305-E?

Don't know how much its worth but from what i have read 20 mpg is pretty good for a 305v6

i'd say 350 for it atleast thats as much as I would pay for it!

Thanks for the feedback guys. And can I consider that $350 an offer if the other interested party falls through?

I'll have to take the time to check the fuel economy manually, but I've made several trips out to were my '72 is stored that is around 130+ mi. R/T. The truck used around 1/4 of a tank or less (though hard to tell when you start on "full") each time. I've had similar results on shorter trips around town as well and my gauge seems to be accurate. My speedo is off a bit though because the truck has taller 16's on it (which will be for sale after the drivetrain swap because I'll be using 5 lug wheels) so I'm sure a normal "count the gallons used vs miles driven" test will not be as accurate as it normally is but I'll figure it as best I can.

I've owned a 305 (a "C" as I recall, though it seems it was not correct for the year) V6 w/3 speed in a '64 GMC LWB Fleetside many years ago, and I'll agree it was not the thrifty fuel sipper that this 305 "E" appears to be. And my '64 had the 1bbl carb as I recall! Maybe it's the way the previous owner has it tuned (timing seems a bit retarded). Maybe it's the cool air gap intake the "E" has vs the type intake my other 305 V6 had. Maybe the truck has a taller rear end gear then normal. I don't know...I just know I've been surprised (and pleased) at it's fuel consumption.


I should have posted some pics of it. A pic is worth a thousand words (of course except when it comes to engines)
