    non-rollers are vastly becoming obsolete, modern oil's won't support the flat tappet cams, especially on break-in. The high dollar racing oils have the zinc required, or the zinc dditive can be added to each oil change/break-in. Hydrolic roller = a happy engine, hydrolic flat-tappet = crapshoot

    More info needed on boat and intended usage. I raced the 429-460 motor in three boats and one play cruiser. The guys here are right about trying to run a std cam, crap shoot with todays oils and technology for grinding cams at the right lifter ride angle for a long life is not good. FWIW I will not run a HYDRAULIC roller to save my life! The last 460 motor I put in a boat was a smaller grind with short duration and iron heads. 18 ft Southwind with a stock berkeley A impellar, no ride plate or shoe and ran 82 mph. I did however move the intake back 3 inches and made the motor into an adjustable rocker set-up useing chevy rockers. M

    Roller is the only way to go! I ran Comp Cam part #(Grind#300A-R10)

    .663 lift 262 Dur @ .050 110 Lobe sep.

    Ran it on a .080 460 and spun an Aggressor B Mag Bronze to 6000rpms. It would still turn around and pull a tube or a Wake board!

    Default cam, build specs

    30 over 460, 9.5 comp, ported doves with oversize stainless valves by high flow dynamics, cam is custom grind from cam research, hyd flat tappet, .564 intake .588 exhaust 238 in 244 ex duration at 50. 110 lsa with 4deg advance. Port p sonic intake with 1050 dominator, bassett headers. Only had the boat on the water 6 times but so far so good, plenty of power, sounds awesome and perfectly reliable. I must admit I did wipe one lobe on the first cam I installed, it was a similar grind from Scotty, I have no explanation as to what happened to it. I know I did everything correct with the install and break in but it didn't last 30 min. I'm not saying Scotty did anything wrong or that the parts were bad, but I now highly recommend cam research and their cam break in service, money well spent for peace of mind.
