Cam/Lifter kits that dont wipe lobes...

[VadersV6]

I was wondering if any of you have heard of howards cams. They EDM a .020" hole through the lifter bases into the lifetr body to allow constant oiling to the lobe face and lifter base. They also use some teflon coating on the lobes to help with break-in. Im thinking this may eliminate the issue with wiping lobes.

The issue isn't usually improper break-in or lube. Many of the 109 blocks have a lifter bore for the #3 cylinder that is machined incorrectly. It offsets the lifter and prevents it from rotating in the bore. Result: wiped cam lobe and lifter face. Then there is the lack of zinc in the newer oils. Zinc helps protect a flat tappet cam from the high pressure, metal to metal contact that it constantly is subjected to. That will affect every lobe, and if the cam was manufactured with cheap metal...... ! It's nice that there's a cam company out there that's trying to solve a problem for us though !

Crower makes "cam saver" lifters too. They have them in both hydraulic and solid flat tappets. The idea makes sense but I can tell you after running them that the 12 additional oil leaks you create by pressure feeding the lifter contact faces does impact oil pressure in the motor.

Havent had any probs with (Comp) HFT cams and ProMagnums... And we run em big and with hvy springs here!

I know what causes the problem. im saying that this company has a potential solution. Plus, 10 weight or 20 weight pushing through a .020 hole is so miniscule that its not going to create oil pressure issues. If it was enough of a leak to create an issue, the lifters couldnt even stay pumped up. Plus, remember that the lobe is always making contact with that hole, mostly sealing it up.

frankg on the board 204/214 great cam super quiet and is very noticable over stock performance wise great pull top end and strong midrange spins tires top of first. throws car sideways on shift

On the lifters Crower sells the solids have an EDM hole in the face. One the hydraulic version they machine a flat spot on the side of the lifter from the pressure land to the contact face. BTW, what's the cross sectional area of .020" X12? Yes, they do impact oil pressure. Ask me how I know.
