Richard, I didn't disagree with Grinsha; I only pointed out when large journal 327's were produced.
327 and 307= same stroke, 3.25" early 327 had 2.30" mains until '68 when they were increased to 2.45". Rods were 2" until '68, then went to 2.20"
350=stroke 3.48"
What about building a 9/16" (3.5625") stroker from a 350? Now that would be unique
