Hey everyone i just pulled a motor apart that i had in my shed to see what was inside. Im not really sure if these sleeves are stock or not. The copper rings and the cuts between the cylinders is making me wonder if they are stock and also on the bottom of the block there are 3 sets of numbers punched into it. Any help would be greatly appreciated!

 

Look stock to me,maybe stock replacement sleeves

 

not stock....those are aftermarket sleeves....fitment/machine work is kinda questionable.....

 

look o-ringed as well

 

sleeves shifted quite a bit

 

Aftermarket sleeves improperly installed thats for sure.

 

Possibly early Benson? Looks like the same type of sleeve. Look where the block stops and the sleeve starts down in the cooling jacket. Also, what are the sets of numbers?

 

Benson doesnt do half *** work like that

 

Not saying Benson does half-*** work, but Benson has been doing it for a long time. This block could be from back in 99-00 area before he was machining in his logo. Who knows how old this block and sleeve job is. If the sleeves are stable, it does not matter. It is the same type of sleeve style that Benson does currently, and without asking Benson himself or possibly Mike at Laskey, you really would not know.

 

I appreciate all the responses guys. I dont know any history on this block. I just know the what the previous owner told me about it, so that is why i was surprised when i saw this. The motor turns freely and i dont see any signs of excessive wear or anything. Here are the numbers that have been stamped into the block. They are on the flywheel side.

 

Do you guys think this motor would be unsafe to run?

 

Def have to resleeve. You cant run the motor at all like that. You wouldnt even get the HG to seal. Depending on why it shifted like that the whole block could be junk. Most likely just have to resleeve tho. im no machinist, Take it to a machine shop (reputable one) and let a professional give you his hypothesis

 

I'd be scared to run it.
