I dissassembled another FE today. I more or less stopped when I noticed the cylinders had been bore .040 over, I have been told this is about the limit for a 390. Out of curiosity I looked up the casting numbers. It was a D4TE that indicates a truck block. When I measured the stroke it came out to 3.625. This doesn't meet the 360 or the 390 measurments.

My question is does anyone know what displacement this was and is it safe to go above .040 before a scrap this block?
