I'm building a 427 using a Ford Racing M-6010-boss35195 block, the block will accept OE or link-bar roller lifters.
Are a good grade OE roller lifter using the factory spider like the Crane or Ford Racing M-6500-R302H as good, not as good or better than a link-bar type ?
Does the OE style use a standard (not reduced) base circle cam ?
I was thinking of using a cam with similar specs to the Ford crate 427, 242/248 @ .050 with .576/.600 lift with 1.6 ratio Crane roller rockers.

Here's what I have so far:
M-6010-boss35195 block
Mahle 4.125" -26 dish Power Pak pistons
Eagle 4" stroke forged crank with 6.25" H-beam rods

I'll be using the new AFR 220 with 58cc combustion chamber heads when they become available, the car is a 64 Falcon about 3000lbs. with a top loader 4 speed and a 9" 3.70 detroit locker

Let me know what you guys think, thanks.
Gary

That would depend on spring seat open pressures. I now run 140 seat and 460 ish open pressures. Knowing the OEM style lifters are not as strong as say the billet Crane link bars I have backed off on racing the car untill I can afford the billet ones. Also haven pushed the engine to its max RPM (some were over 7200 still pulling strong) for the same reason.
