Hi Hal

I have not yet received your info on the fellow in Eugene, OR but certainly look forward to meeting him. We are headed for a rolling rally put on by the GMCcascaders this weekend in nearby Albany, OR so if the info comes we will try to contact him. I assume he will allow a 78 Royale to grace his driveway (grin)!

Mia copa on the rounding up of 12.7 to 13 liters. Same for going off memory and saying 1600 instead of 1550 for the torque. I will check tomorrow but think the CC literature from 1997 listed the HP at 475 instead of 450. Maybe they were wrong but I doubt that it matters much. As RR used to boast when they did not spec things like HP, instead responding "adequate". I don't think I can tell the difference in any of this.

I look forward to lots of wisdom from you as I climb this most interesting learning curve.

You're probably right on the HP making little difference. Sorry, I'm just a numbers guy and the two engines are completely different. I changed my 12.7 from 450/1450to 500/1650 and it sure wasn't worth the big extra money invested. Now the 14 ltr I installed, that's a different story.
I sent you a PM with that information. Let me know.
Hal
