    Cam dynamics use to make solid roller lifters that had a piece of wire between the 2 lifters for the "guide". I've sent the picture to a friend that...

    It's going to depend on the use or abuse. The 200hr mark seems to be what Merc Marine uses. If the springs are in spec, you can continue to use them...

    There is no load on tie bars. When a tie bar breaks the engine has harmonics in the valvetrain. From the pictures you posted on the other site, you...

    Those are street series lifters. They have been run way beyond their intended use. Any time you see tie bars breaking like that it's due to serious...

    hi there,
    i can tell just by reading your posts that you have a lot of great experiance and dyno time.
    i wanted to ask you a question if i may.i scabbed together a 477ci bbc from a 100 over 454 block, gm steel 4'' crank,6.135 eagle h-beams,high dome (50cc) ross pistons,and a set of old s\r dart 320 heads that have a 4.500 chamber 115cc's 2.250\1.880/11/32stems, clay smith solid flat cam [email protected] 630 lift., dart open plenum int. and braswell 830 winston cup carb.
    this engine runs great! never dynoed but must be bumpin 700, anyway my question is because the heads have larger bore chambers and pretty big for this app. the were super mod ported by dart said to be 327int.
    would i be better off running my other set of dart heads that are 310 un touched and std. bore bbc. with 2.30x 1.88x 3/8 stem.and 115cc's??
    ross told me im at about 14 to 1 comp. as is.
    any suggestions would be greatly appreciated...
    thank you mike d.

And I am open to any suggestions please let me know. THANKS JD
  3. Hey Dennis,
    What kind of experience are you asking about? I've never had a set in my hands, but AFAIK, they're no different than any otehr BB Chev head as far as how they work or how they're made. What casting are they?
    How can I help?
