There's nothing more comforting than building a fresh engine, turning the key and knowing that the cam won't wipe a lobe....or not having to do a break-in dance for 30 minutes while keeping your fingers crossed and offering sacrifices in the corner of the garage. |
true dat..
Another thing of concern to me.. I'm starting to hear of more "after the breaker in" wiped lobes these days with flat tappets. Some of the SBCs, I'm hearing, are trashing cams 10,000, 20,000 miles after they were rebuilt. I'm starting to wonder if the non-roller cams require additives on a continued basis. Todays agressive ramping, duration and lifts, unheard of 20 years ago, may have surpassed the "long term" capabilities of the flat tappet, hydraulic or solid. Maybe today's automotive manufacturers have already realised this years ago, hence to demise of the OEM flat tappet. It would appear that "retro" will come at a price, with risk!
