Thanks guys. The heads for it are in use now. I redid them 2000 miles ago and their springs are perfect for this cam. However they still have the two piece keepers & I need to find out if there is a one piece available to fit, preferrably lighter. Intakes are 1.92". The aluminum 4V Blue Thunder intake and alum pump also will be changed over.
A steel billet flywheel lightened 5 lbs may be a Christmas present.
The truck should get 20 mpg with this motor, rear end and light gross weight, possibly up to 24.
