    Could also be T/A uses Chevy type lifters too. I don't have any lifters here, but maybe someone has a stock Chevy they can put alongside a stock Buick lifter.

    Yeah that is the pic I tried to load, thanks Mart.

    And I was ALWAYS referring to the retro fit lifters with the link bars that are made for engines that never came with roller lifters from the factory.

    In the pic the set on the left are hyd. rollers made for a sbb engines and the set on the right is a solid roller set for a sbc. As you can see the oil hole is pretty close to the same spot so.............? Or were you referring to the factory style in a non-roller block? If so I would of NEVER of even thought about the sbc ones from the factory.

    No, Just experience and others trying to use flat Chevy lifters in a Buick. Retro rollers are usually smaller basecircle cams also. The stock Chevy rollers are longer than the stock flat lifters too.

    Here is an old picture I found. It may be brand related. Also Chevy pushrod seat .060 lower. Oil band lower/ floods rockers. I found out about the difference with 215/Rover and 300/340 lifters vs Chevy. Chevy on left. Buick on right.

    So can we bottom line this? Will the Cheby roller lifters work? Which ones, factory or retrofit? Is there a need for a spider or can we get rid of that part?

    Jim, I've never used the link rollers. I think with a smaller base circle cam the oil hole is lower. The band also being lower may over oil the rockers and need pushrods with smaller holes. The one on the right in Dereks's picture is a solid roller. I still think the GM 2.2 four and 3100/3400 V6 short roller lifters with full base circle cam are the best street setup.

    Which requires the dogbones and spider I see. So, cut and splice two Buick V6 spiders?

    That would be my plan. Now if we can get a inexpensive roller cam for the old motor! Didn't mean to hijack this thread, but these parts will fit a 300! Remember our old thread on BritishV8. You can upgrade the lifter with LS springs and circlip instead of wire retainer.

    The retro link bar roller lifters DO NOT use a small base circle cams unless you order the cam that way! Not sure where you pulled that out of? Even in the sbc engines they are NOT small base circle cams with the link bar lifters unless you're running a 3.75" or more stroke with a 5.7" or longer rod, then a small base circle cam should be ordered with lobe lifts .334" or higher for the 3.75" stroke. With an even longer stroke then 3.75" with a sbc a small base cam should be chosen from the start of that build.

    The factory sbc roller blocks have deeper lifter holes, that is why the FACTORY roller lifters are longer.

    The link bar lifters are the retro roller lifter style for the NON-ROLLER factory blocks. They even make the link bar lifters for the factory roller blocks that are .300" longer because the factory ones aren't very good performance lifters and they don't make a solid factory style roller lifter.

    Derek, Thanks for the clarification. I haven't used a retro roller cam either. I have read they were smaller base circle. Evidently allows the longer stock roller lifters to work in a non roller block. I did know the roller block lifter bosses were taller for the stock rollers.

    A small base circle cam was never meant to use the longer factory roller lifters in a non-roller block.(period)

    Like you found out and mentioned earlier, the sbc factory roller lifters are .300" longer than the non-factory roller lifters BUT the small base circle cam is only around .200" in diameter smaller. With only .200" smaller that is only .100" shorter per side which means the lifter would only sit .100" lower, not the .300" lower it would need to be to run the factory style roller lifters.

    (standard sbc roller cam base circle varies and is around 1.100" to 1.150" depending on manufacturer and the reduced base circle cams are .900" to .990" also depending on manufacturer)

    The sbc small base circle cams are meant for factory block or after market blocks with the standard crank to cam distance for builds that have longer strokes that use longer than factory length rods for more cam clearance.

    Same deal with the non-roller sbc blocks, people run the shorter v6 factory roller lifters in them with a little bit of "fitting", drilling and tapping to run those.

    A retro roller cam can be the same as a factory roller cam with the same lobes, the only difference is the front of the cam where the factory cam is shouldered for a cam retainer on the front of it with a smaller timing gear bolt circle than the retro cam that needs a cam button of some sort.

    Sorry everyone for the sbc 101 class.

    20180329_230348.jpg 20180331_200328.jpg Here's a retro fit sbb hydraulic roller compared to sbc solid roller. A bit shorter, but much much lighter.

    Those look pretty good, has anyone actually run them yet?
