Best hydraulic flat tappet lifter?
Weren't there only a couple of flattappet lifter manufacturers back then, and now?
I put a comp xe268h in my 340 recently with their lifters when I start the Engine it clatters for a couple seconds until it has oil pressure.
I called comp and asked them about it, his response was what do you care if it clatters until it has oil pressure?
I just said well it never did that before?
So I called Lunati the guy there laughed when I told him comps remark, then said honestly I could say our lifters are better but the fact is there probably made by the same company.
He suggested Johnson or Johnson Hy lift
Two different companies...
I've been just living with them being noisy at first start up.
I did just switch from Penn Grade 20w 50
To their 10w 40 and it's better.
