[DeTomaso] POLL: Are you running a Roller Cam in your 351C?

[Doug Braun]

(Hand is raised)  I'm running a hydraulic roller in my Pantera and plan to
install one in the 70 MACH1 351C-4V based 393 stroker engine I'm currently
building.

Just interested in how many of just the folks on this forum (never

their 351C powered Pantera.

Please raise your hand.
