The Stovebolt Forums Forums The Shop Area The Engine Shop Identifying inline 6

Hello all. I was hoping someone would have some insight on an inline 6 I have in a 66 C10 with 3 speed. I'm unsure if the motor is original to the truck but as far as I understand, 1966 was the first year for the 250. The numbers I have been able to gleam from the block is the block casting 3877178C which just tells me it is either a 230 or 250 (although I don't know what the C means). The code near the distributor is F0219FA. I can find just about every suffix code online other than FA. So far I can determine it was made in Flint on February 19th from that code. I can't seem to find the date code near the starter. The only other number I've found is CON2. I haven't been able to make out the shape of the pistons which would at least tell me if it was a 230 or 250. Any info would be appreciated. Thanks.

A borescope that will fit through the spark plug holes costs about 30 bucks on ebay. I use mine all the time for inspecting engines, and it even fits down barrels as small as .22 to inspect the condition of the rifles I buy. Mine has a mirror attachment that lets me put it through a hole and look sideways.

Thanks Hotrod. That's actually on the list of soon to buy toys.

I believe 67 was the first year for the 250. Oops. GM Heritage site says I'm wrong. Looks like my source, John Gunnell was wrong too

Hey Jerry, can you let us know the specifics of bore scope (manufacturer name, model #) and what/how you hook it up to to see what you're looking at?

Someone posted a link to a nice borescope (maybe Jerry?)

I'll check tomorrow what brand (I bought one and it is cool/helpful).

Believe it or not I found the original Protection Plan book for this truck which lists the original engine number as being F0112TA. This means the truck's original engine is no longer in it. As for a bore scope, I will probably be ordering a Goodan brand 1200p tonight.

Found the FA code, it's for a '56 230 or a '66-'67 250 from full size Passenger car with manual transmission.

Thanks Longbox! That's good to know. May I ask where you found this info?

My borescope was an Ebay purchase, but I don't remember the brand name offhand. It plugs into the USB port on my laptop and projects its image onto the monitor. I did a little shopping for the smallest possible diameter of lens (5 MM) so I could inspect chambers and barrels of small bore rifles. A somewhat larger lens would probably give a sharper focus for engine inspections if you don't need to access very small holes. There's a wide variety of choices and prices, and like anything else, "Ya gets what ya pays for!"

When the borescope and the headspace gauges come out at a gun shop, the prices come tumbling down, on occasion!
