Hello all,

I have hesitated to post this question as I have tried to find a functional search feature without success, so please forgive in advance.
My question is whether or not the B9AE-6015-F cylinder block can be safely overbored to a stock 312 bore size (3.800")?
I see a lot of references that say this block was used as a 312 base if it came with the ECZ main caps but since this engine came from a truck, it seems unlikely that I will have gotten that lucky.  I am not yet in a position to tear into it quite yet but am trying to get my head around a reasonable build plan ahead of the teardown and inspection.  Thanks in advance for any help and humoring a rookie!

Regards,

Sven Pruett
