I bought a 350 block that supposedly came from a 1 ton dually and I wanted to verify some info.

I haven't had time to crack open the motor but was wondering if anyone could tell what it was.

The casting number is 10054727. www.mortec.com says it's either a 2 or 4 bolt block and is made in canada.

The engine has the oil filter housing that has the outlet and inlet for an oil cooler.

What are the chances of this being a 4 bolt block and/or being a roller motor?

Thanks in advance.:lala:

BTW, to keep it thirdgen related, I'm putting this motor into my 86 T/A

 

Being a truck motor, logic would tell me that it would be a 4 bolt main, non roller block, but you cant be for sure until you break her open.

That casting number can be either a two or four bolt main and some of them where made in canada. But I do have to agree that if it was in a heavier duty truck it is more than likely a 4 bolt!! :lala: :lala:
