[DeTomaso] Rocker Arms

[mark skwarek]

Just make sure that you have clearance between the pushrod and the rocker base at full lift. Under high lift the pushrod can make contact with the base of the rocker arm. Them the end of the rocker arm end will break off. Been there, done that.

 I like the Scorpion Endurance SCP3023 1.73:1 forged aluminum roller rockers.
They have a hardened insert seat, the shaft is centerless ground, a 7/16"
poloc nut is included and they have a great lifetime warranty.  $326 a set
at Summit Racing.
Max spring dia = 1.625"

I'm running these on my 70 Cleveland Mach1 engine.  Please note though that
if you intend to run 7/16" dia pushrods, their backsides need to be
clearance for them.  Scorpion's Endurance series cost more than the Race
series but they have a narrower body and shorter polylocks so they fit
better under stock rocker covers.

351C, solid flat tappet cam with lift of 0.640.  7/16 screwed-in studs.  Any
opinions on Rock Arms? PRW vs. Harland Sharp vs. other?
