> We think a 3.85 stroke is all that is safe.

What do you base that upon? Dave McLain used a standard 351C block for his
Engine Master's entry with 4" stroke and 6" rod. He said it worked out
just fine and I know of several similar street engines running with no
problems. A local Pantera owner is also doing a 4" stroker 351C. A friend
runs a 4.1" stroke with 6.125" rod in a 9.5" deck block, also with no
problems. 3.85" is conservative but it depends upon the RPM you plan to
turn. My Fontana uses a 3.85" stroke but my back-up motor will likely be
a 4" stroke.
