Re: Cylinder Head Runner Volumes
There is a problem some of the small block Mopar SS volumes are incorrect with the valves we can now run. I've checked many untouched small block mopar heads this year and very few have four runners that will meet the ss volumes (only one out of twenty heads for the 915's I checked had four runners that were less than the ss volume of 158.). The 587 head is the only exception,it has the same port but there is 4 cc's difference in the super stock spec.
I was told at the pri show the stock volumes were decided on Thursday evening and would be on the NHRA site Friday or Monday.
Thanks
