    Oil Drillings - Brayton "Indy Lights" Engine

    Engine stripped so made notes of oil drillings - might be of use to others. Notes - - dry sump oiling - feeds into front of RH gallery via -10 external hose - rocker arms etc oiled by -03 external hoses from RH gallery - lifters oiled by 1/32" drill holes from galleries (original holes blocked)

    RPM Kit

    1 - valve springs were Ferrea's recommendedation - I hope they were good. 2 - How do I identify minimal harmonics? Typical race RPM is 5800-6500, with occasional 6800-7100. Engine does have harmonic balancer, came with engine, do not know specs. Engine is SII, on center, even fire. 3 - by "valve...

    RPM Kit

    Sorry - Rev Kit - not RPM Kit - just shows I'm not really an engine guy. My engine was originally built by Brayton Engineering before George Montgomery got the business. It came with a Rev Kit - see pic below taken earlier this year. It's possible but I doubt it that a previous owner added it...

    RPM Kit

    At what RPM does an RPM Kit become necessary? Just bought new valves and valve springs from Ferrea and they say with their valve springs RPM Kit not necessary - keeping to 7000 max. Anyone agree? Disagree?

    Oil Feed

    Stage II - 252 - NA - road race. There are two main oil feed locations - one front, one rear - both feed directly down into the main oil gallery. Does it matter which one is used? I changed from front to rear at last rebuild (2013) and now notice more wear on front main, rod and cam bearings...

    Cam Bearings

    Roller bearings sound interesting - but some major machining required I guess. I should have replied to my own first post on this topic. Clevite info says SH1360 only available singly, not in sets. Summit says "n/a" - order SH1385S instead. But Summit do offer a set of SH1360 - just order...

    Lifter Bore Size

    Great stuff AG - may be elementary to you - but most helpful to me to understand the specifics. I was an engineer but became a racer in retirement! My engine was originally build by Lee Brayton for professional road racing. (Lee also built many stock block turbo Indy engines years ago.) The...
