Solid roller failed again

[undy]

Solid roller on the street... in the past, today and tomorrow, a very slippery slope that typically ends in disaster.

Bermblaster41 The cams shaft was repaired by a machinist that made the surfaces harder on the damaged area. Higher rockwell rating. This is why no damage to these two lobes.
This subject have been beaten to death over the last couple of years. The issue is can you run a solid roller lifter camshaft on the street. Yes you can,BUT here are the problems. IMO if you are street driving, you want to run a tighter valve lash that looser one. Idling for long periods is a NO-NO. unless you have sprayer bars or pressurized lifters with pin holes to lube the roller wheel and bearings. All it take is a small piece of debrie to get between the roller wheel and the lobe of the camshaft and you have major failure in 2 minutes. Be there had this happen on a new motor. Windage trays canalso cause problems. They stop spray of oil in the bottom of the motor. The oil is not sucked up by crank rotation and less oil is hitting the camshaft and lobes. A fix for this is to run a .010" groove from the lifter bore down to the inside of the lifter area to drop or spray the lobe and lifter surface. This is an old solid lifter trick for extending the lift of solids.
Oil is the main problem with all motors today. IMO too thin and not enough grip to cool and lube parts. I am old school and run Lucas oil suppliments for the last 13 years. No motor failures from roadracing and autocross. An FE motor is not the same as a Windsor but both need te same thing to live long lifes. Good parts and good oil pressure and flow to all areas.
Is it possible that the lash is a little loose? The valve springs are a match for the camshaft profile but are they too much for the rpms you drive in?? If you have a little time could you give us the specs on the camshaft, rpm range YOU drive, valve spring #'s? The spec you are running on the valve spring bind would also be wanted.
Berm, the hardest question to answer is What are you looking for from this motor?? HP, Torque, Drivability, 7,800 rpm range. If you give these specs and have some FAITH, I see no reason we can't give you a strong motor for your car without breaking the bank. Rick L.
