U67 Head Rebuilt $350 EDIT

[brodster]

Will you take $350 shipped to 95135 San Jose CA?

 

I would only accept $350 plus shipping at this point.

 

Also, I need to update that I have a trade pending right at the moment.

Many cam makers and re-grinders measure their cams differently. I see that the advertised duration is 282 and the overlap is 54 yet the drawing shows 236 and 16 because it is measured at 0.050" lift. ??? Very confusing to the buyer.

 

For future reference, one and all~

Cam makers and regrinders do not measure their products differently~ they collectively use two methods of measurement neither being specific to either market. The two standards used are: 1. degrees duration @ .006 lift~ This duration measurement's taken (and dates back to the advent of aftermarket cams) because at .006" all lash has been taken up in the valve train, and is preloaded and ready for action! In this example we're talking 282^o. The second standard is lift @ .050"(here 236^o ). This number was chosen because research has shown that at this lift is when a measureable amount of airflow begins to take place, and gives a more accurate picture of performance potential. The difference between the two measurements can vary depending on ramp shapes/designs, and lifter type.

 

Hope this clears up some of the mystery....

 

Peace~

Good information. Thanks

With all due respect to Hainz, I know exactly how his replies can come off. IMO, it doesn't really justify anything. And deleting his post won't really change anything.

 

To be honest I am pretty much over pressing the issue. This horse is dead.

 

I'll take it...I'M in NY 11367. send me shipping charge.
