Mopar flathead 6

Iskyn nokasta löytyi tämmöinen keskustelu. Ilmeisesti niitä on muitakin. Keskustelussa timkingsbury kertoo parista muusta:

"Its too wild for the street and has an issue with creating vacuum. That pattern was modified by Iskenderian to make his #1023 cam for the 1/2 mile an long tracks dropping the duration to 250 degrees and its pretty wild for the street. tech specs - intake opens at 20 degrees and closes at 50 degrees, and exhaust opens at 57 degrees and closes at 13 degrees, Duration .250 and he reduced the lift."
