I bought a set of Enginetech Hyd. BBC roller lifters today. I have seen these before and told that these lifters are Johnsons, but for $212 delivered to my door this Thurs. I am willing to try them. I want to run a Hyd roller cam in my L-29 headed 461 BBC so now I have to find a cam to use. Being I have roller lifters, I just need some good springs (beehives) and I can see if there are any cheap rollers out there to buy and test over my current flat tappet cam that ran pretty good. Not trying to cheap out but I am unwilling to spend $5-600 bucks on an engine that will only see 6K from time to time.
