    Default What solid lifters are best

    Looking thru all the data on different solid lifters and was wondering what your running and how they are holding up for you.
    bushings or needles which is better? Thanks.

    I have had very good luck with the isky ezx red zones that are bushed (not to be confused with the neele bearing red zones), and a friend of mine swears by crower severe duty. If your doing a bbc and the budget allows, opening up the lifter bores and running a 904 lifter sure does add piece of mind regardless of the lifter you run. But for sure whatever you get, as stated above, get something that has pressure oiling to the lifter axle.

    I am a HUGE Crower fan. I just bought my first set of Morels to compare. Both severe duty, edm oiling, etc. NOT bushed. Just needle bearing rollers.
    I have been racing boats since 99 and had 1 crowel failure.
    Before that, ran the f... out of em in stock cars.... very reliable pieces.

    If tons of spring pressure... use bigger diamater lifters, and take advantageof the bigger diam with cam profiles.

    I gotta go with these... Crower severe duty, many many years of PS racing without any issues... Also use the Crower rockers.... Not a single valvetrain failure....

    The devil is in the details and I can say the Morels have more attention to critical details than any other both in materials and manufacturing.

    I have seen just just about every lifter out there, For sizing I like the Morel lifters they always seem to be with in .0003 and are to OEM sizing.

    Now Crower and ISKY seem to run up to a .0015 smaller then OEM and I have seen sizing issues.

    90% of the blocks I machine now most guys are going with the .904 lifters. Bigger axle, Bigger body and bigger wheel which means less revolutions around the lobe, less pressure angle.

    Plus I am seeing alot of 55MM cams used in the SBC, BBC and SBF bigger cams need bigger wheels for slower wheel speeds.

    ISKY does offers Durathon roller lifter made by Morel which are more to OEM size


    Here is a perfect pic of to much lifter bore clearance with alot of bore clearance the wheel will not square to the lobe which will cause a wheel failure.

    Thanks for the input. Can .904 lifters be run on a stock cam base circle? What was the second lifter in the video? I am leaning towards the isky bushed lifters thou I have always had good luck with the crower sever duty lifters. Has anyone tried the crower bushed lifters? Are the morals a bushed lifter or needle bearing lifter? Thanks again,

    Yes let your Cam grinder know what size lifter as they may have to narrow the lobes.

    ISKY lifter make sure you measure every lifter for size and taper!!!

    Brian from the Nova site called me last nite and his Crower bushed lifter failed, But his lifter bore clearance was way to much IHO I wouldn't blame the lifter.

    Morel you can get either way.

    Don't know what lifters were used in the video.

    I went with the isky's on my last set up and this one after reading about a lot of the drag week guys using them, the only upgrade I did this time was the 904 deal. That being said I have heard pretty much every time they need to be sized, everyone says the morels are done with very tight tolerances, and a lot of people swear by them. With shaft mount rockers I put 400 miles and 30 or so passes on the stock diameter isky's with 800 lbs over the nose and only checked, never had to adjust a single one.

    I talked to Chris and went with the Morel's none bushed lifters. He had very good info on both and the in's and out's of using both sets. In the end the none bushed lifter were my choice for this lake boat build. Thanks Chris. Can't wait to get the from you! Should be here today. Jay
