From reading past posts it sounds like the Johnson roller lifters are the most reliable? But apparently they do not have a listing for the 300 for solid lifters. Jim
If TA lists a solid roller lifter for the 215-300-350, I'd say there is a Johnson lifter that will work just fine though Johnson may not list it. When I swapped over to Johnson lifters from the Morels, I got them from JW. Pretty sure they didn't list it for the BBB. The push rod cup depth was different, so I needed to use a different length push rod. You'll need to do that anyway.
What do you suppose is the difference between the light duty and the heavy duty? (TA1413-2 and TA1413-3) I'm planning about .500 lift due to street use and the blower. Max spring pressure at full lift would be about 335#. Is there a particular reason to use the Johnson lifters rather than TA? Jim
The TA lifters might be the Johnson lifters. I would call them. The Johnson lifters I am using are much quieter than the TA Morels I was using before.
I don't think solid rollers will be quiet anyway, compared to hydraulics. No such thing as quiet solids.
Yes, but Mark and I are referring to the hydraulic lifters. The Johnson lifters are better hydraulic lifters. Not sure who makes the solids that TA sells. That's why I told Jim to call TA and ask. Yes, solids will not be as quiet as hydraulic.
Yes, go with the Johnsons, After reading Larrys post awhile back. and then the issues I was having with the Morels pumping up, then bleeding down...... While driving Then reading about Johnsons quality control, I was convinced to go Johnson, especially reading about needle bearings falling out, jamming the roller then ruining the cam. I puckered up and spent another 900.00 for the Johnson rollers AND new pushrods AGAIN Ironic thing is, the Morels are thought to be the saving grace in the Turbo Buick world, suppose to be dead quiet compared to Comp Cams rollers. Years ago when I went roller on my GN, the cam and lifters came from IIRC, Precision Turbo and Engine, the lifters are quiet, even on start up after sitting for weeks or months, I hear a very very soft "ch ch ch" for a second, and they're pumped up ready to go, they must be Johnsons too
