The kicker is that if it's an SR block that's been built as a 360 and not bored out to 401 size it IS worth a great deal more. The thick sidewalls come in handy for long distance racing and lots of boost. Once bored out to 390/401 size it's just another 390/401 block. ----------------- Date: Sun, 4 Sep 2011 20:14:30 -0700 (PDT) From: Jesse<j2sax@xxxxxxxxx> Thank you loads Ken!? When I saw the 3 hole balancer and the dog leg heads, I had a feeling it was a 360... still has a nice set of heads on it, though it's not worth 401 price!? May buy it anyway to run in my Propane truck... that extra compression really comes to life on propane!?
