Maybe I'm missing something, but what the point of doing 102.7 mph in a motorhome?

catblaster said:A note on the Olds oil starvation. I can't speak specifically about the olds engines but the caddy 472 and 500's have bearing journal so large in diameter they tend to wipe the oil film off the bearings at high rpm's. I mention this because I had heard they used some caddy motors in the GMC motorhomes.....don't know that to be true and hope someone might enlighten me.
The Olds engine needs the Mondello SP-754 oil pump. (high volume) Used it on my jet boat with the 455 engine. They also have a 756 pump(high volume and high pressure), but you need the larger oil pan also.V2Neal said:I can't say about the Caddy engines, but the Olds oil galleys that feed the main bearings are 3/8" diameter. At High RPM they don't have enough flow/pressure with a standard oil pump. The fix is placing bore reducers into the mains.
I learned all this after spinning a rod bearing in my 1970 W-30. :'(
