Mike;



I saw your comments about the custom tuned Holleys that Larry has, and I have

a few questions.   Can you custom tune a carb without knowing the specifics

of the engine it is or will be used on?  I know very little about Holleys,

even though I got one (650 double pumper/merchanical secondaries) on my

Pantera.   I would think that the breathing characteristics of the engine,

such as the manifold, cam grind, and exhaust system might affect the carb

settings.  Or are those factors not significant?  Are the custom Holleys

different in parts or features, or just careful, detailed calibration?



How would I make a guess as to whether my car would benefit from the custom

Holley vs my own.  I have no symptoms, as the car runs fine.  I could assume

the previous owner (before I bought it in '93) had somebody do a good jetting

job, but I don't know.  All I have done to the carb is rebuild it due to

leaks from dried out gaskets, etc from I assume lack of use by previous

owner, and adjust idle mixture screws.



By the way, I will have some Vegas pictures to get to you, some of them maybe

even decent.........
