Killed another flat tappet cam in the w2 stroker so now it’s coming out of the car. I’m sick of this **** so now im looking to go solid roller and I need something pretty nasty… 600+ lift and 250-260* duration at .050” lift… street race/race on pump gas- here’s the setup-ported closed chamber w2 race heads, 3.79” stroker crank 360 (387”) victor w2 intake, 1.6 ratio rockers, it’s got a 3800 stall converter in it right now, but some of this may change depending on how crazy I get with it… my question is who’s roller lifters and cams can you recommend at this point? Do I absolutely need to bush the lifter bores?
