I have T&D roller rockers custom built on my 451" Mopar stage 6 heads. Just wondering how long they will last on a street motor? Anyone have experience with them durability wise?
Thanks Brad



I have them on all of my engines.. on the race stuff
I have at least 4 years on them turning 8200 rpm with
320# on seat and over 800 open.. I have them on my
street rod but I only have about 500 miles on it so
far.. thats with 260# on seat and 600# open(all solid
roller cams).. if you have to change the valve lash
you have problem parts... after the first recheck I
havent had to change lash at all(no more than .001
variance)
