Hard to compare small block stuff with big block stuff. Under $200 you can use the GM Performance lifters and run your SBC like a buzz saw. Much lower valve/keeper weight, much lower spring weight, and pretty straight valvetrain.

I forgot to mention the other week cause we where without power and internet for 6 days (brutal massive storm), but just before then I found a company that makes limiters for hyd lifters. :)

Harley uses, on many engines, the SBC lifter. :) So, leave it to S&S cycle to make it. These should fit in the BBC GM HR lifter too.

So far, mine are doing great. I have used them in the last 4 engines that I built, but probably less than 200 hrs combined on all 4 engines. The last two were 548's that we dyno'd to 6300rpm with no issues. They had pretty big cams and pretty stiff springs.
