Building a new 505 With Callies / Mopar Performance Block

Are those Harland Sharp rockers or the one HS makes for Mancini?

I ask because if they are the Mancini rockers the geometry should be very very close. If they are HS rockers I would call Mike at B3 Racing Engines and see what he says about correcting the geometry.

It’s better to find out now and buy pushrods once.


These are the Harland Sharp that Trickflow recommended for their heads.
The geometry looked really good when I had the checking springs on the heads.
I am remeasuring for pushrods because I cut .040 of the Trickflow heads to raise my compression ratio.
