[DeTomaso] 408 Stroker Life Expectancy

[adin at frontier.net]

Somewhere in my travels recently I was looking at a stroker motor that  
someone was very proud of . . . and noticed the wrist pins 1/2 out of  
the bore at the bottom of the stroke !!!  (easy boys)  Reread what  
Jack had to say about piston rock.

In Art's case, and mine, it seems a litte less severe setup would be  
prudent.  Unless you can call the guys in the motor shop and get a  
spare motor for practice tomorrow!  ("Yeah, this is THE cat in the hat  
- got a good qualifying lump ready?")

It seems that the Clevelands don't lend themselves to stroke as much  
as Windsors.  Must be short skirts or something.  Never thought "short  
skirts" and "a time and a place for everything" would ever be in the  
same paragraph.

Seems like 377 Cleveland stuck in my tiny little mind somehow.

Some dirty thoughts from Durango
