Re: What about the 25K 105mph V8 Patrician?

Yes rusty i would agree 100% with your post about the V8 and streight 8 tests performed by PMCC.

The only thing i would question which is not clear from your post is whether or not the streight 8 was run at 100 mph too altho i assume that it was.

I will further assume that at the 18K mile mark that the streight 8 had failed due to catostrophic internal engine failure such a crank or rod breakage. Best case piston rings worn completely out to paper thin thickness. Off the top of my head the stroke of the 54 8's is in the 4-3/8" range. No way could the rings last at those speeds. I'm surprised they got 18K miles out of them at 100 mph. Well maybe, if they were running an extremely long axle ratio in the neighborhood of 2.80 to 3.0 or less or an overdrive.
