I don't criticize others religion but personally I don't worship at the 427 alter.
I do remember the '68 NHRA Nationals where the CJ Mustang was introduced to the public. I don't need to explain the results.
427, yada, yada, yada...what's the point of an engine that will drop a valve over 6,000rpm's?
EVERY original 427 Cobra I looked at had either a blown engine or a replacement in there.
All things given equal a CJ is half the price so is twice the value of a 427. That is unless you are going to Lemans and in all honesty, I never did.
All FE's are 6,000 rpm engines UNLESS you go in and rework the valve train. Mostly valve springs but salt belongs on the dinner table in shakers, not in valve stems.
Don't like that remark? Who cares? Pick a finger. Any finger?
