440Source Solid Roller Lifters

I don’t hate China stuff. I have a value priced connecting rods and crank in my motor.

However, I would never never never ever put low cost roller lifters in any motor, or any low cost valve train components.
Neither do I. We don't have a choice. Scat, Eagle, Molnar.....all made in China. Unless you can afford Bryant, Callies or the like, those are your choices. I remember I think it was Eagle that had the crank breaking trouble right at the first throw, so I wouldn't use those. But I've not heard or read anything bad about Scat or Molnar.
