So why was the 'W1' BigBlock heads not progressed?
They had proper cooling and a heat crossover like a passenger car head.
Open chamber as per the 906 head and the extra cooling passages like the motorhome heads of 76/78 etc.
Also had the strange taper seat spark plus also like the motorhome heads!
D-shaped exhaust ports became all the rage in the 70's...
If the fuel crisis had not have happened in 73 where would we be now with heads?
This engine and a few hemi heads is all that remains of the once glorious 'Mopar branch' Weslake Engineering of the UK
