Hi!

I need help again.

I'm looking for roller-to-roller specs on 5.7s DB2825 SF3975

It is near (J-code) 1.981"
I think it could be greater ...

Does anybody know for sure the specification?

It was 1.981" and runs like never before :).
Sum, sum, sum....

Don't know the answer to your question. Was interested in the truck in your avatar. Is it Olds 350 diesel powered?

Yes, It is Olds 350.

Thats awesome! Must be a 1981 since that was the only year that body style came factory with an Olds 350 diesel. That is a real rare truck. Its a great looking truck. Thanks for the info.
