What EDM lifters do you like?

I have a similar very old 80's Crower list
something else for the gang to chew on
check out the 1" base circle masters below and above
note either the greater seat duration or accelerations to get the same upper numbers
I've run under .900 base circle on 4 1/4 stroke chevies- lots of fun trying to get performance and make it live (stock rockers back in the day)
for those looking Mopar has base circle closer to BBC than SBC
as with flat tappets SBC roller masters leave a lot on the table in a MOPAR
(end rant)

I agree 100% That is why I picked those to show how a mopar style flat tappet master, with a mopar base circle with be about the same performance wise when on the dyno. Running them back to back "roller vs flat tappet, in mopar land, for the average guy/engine" You will get very little performance gain. How ever when looking at the masters used for my small block mopar solid roller cam the velocity of those master are in the 1000 range. Its a drag race engine so little street driving only to the local cruise. That engine has 1.6 rockers and with those masters the valve velocity is through the roof. Below is a cam card if you want to take a look. The cam card is the "When everything happens" What you cant see is how fast. Oh one more thing the advertised duration on this cam card is a lie by alot ha ha ha ha.
