<VV> GM lifters question

[BobHelt@aol.com]

Calm down there Mr. Lon,

You may think that this is inaccurate information simply because you are just 
not aware of what has been done concerning lifter research. I was quite 
involved in the research and testing that was done on these lifters, and thus have 
a first hand knowledge of this evaluation. So I can speak with confidence.

Since the actual data and results may be propriatary, I suggest that you get 
the complete story from Dave Herrin, of the Source, himself who initiated this 
evaluation. 

As to the Deep Dimple nomenclature, these lifters have a pushrod seat that is 
deeper than a lot of currently available lifters. I know that Chevrolet sold 
a bunch like this. It was just this week that I was informed of a lifter 
adjustment problem that resulted from the use of a shallow-seat lifter (pushrod got 
seated on the edge instead of in the seat). So I know that a lot of them must 
exist--and I have seen a bunch myself. Is there something about the use of 
the term, Deep Dimple that bothers you?

If you also are selling Deep Dimple lifters that are identical to these sold 
by the Source, please let me know (with some kind of assurance-maybe 
paperwork?) so I can also recommend CU as a source. 

Regards,
Bob Helt
