[Cuda340]

I also have been running the tool steel PPPC lifters but on a cast P-55 core the last 2 yrs but prior to that i used the Shubeck?s bomb lifters (but never experienced a failure with then but lost many a nights sleep when running them lol ) in my hi-comp 1970 340 Cuda all from Brad Van Lant, maybe ask around with the older stock racers as to what they are using and any tricks,I?ve found all the 340 guys have been very forthcoming with majority of my questions,many people out there close in your area that have run the Chevy 305,350?s,Warren Eng. in Clinton,NC is who I would seek out,or Jim Marshall just south of you in SC or there are many others,GoodLuck 👍🏻
