Hello all, wanting to go to a roller lifter on my purple shaft, hydro flat tappet cam, any drawbacks or extra work needed to run, or is it even possible? Have 1.6 steel roller rockers, should I go hydro or solid lifter? Running 100-200 nitrous as well. Havn't bought push rods yet so not a prolem there yet.

theres nothing to worry about putting rollor lifters in, drop in deal, cam hydr or solid both are good if its going to be a track queen then id go solid, if street drivin quite a bit then i would go hyd,

I run a roller cam in my 440 Dart....the cam is made from billet steel...you must use a roller cam with roller lifters...a bronze distributor gear and if a big block a bronze tip fuel pushrod...either hydraulic or solid....hydraulic for street...solid for track and 200 shot....M2C..no roller lifters on purple shaft cams

ok. thanks a bunch guys, the roller cam itself is only another 100-150 so def go for the roller cam/lifter kit.

The cam should be 300.00 and good set of roller lifters 500.00 and a good set of adjustable rockers 500.00...its no cheap but these are what you need...Eric

Thought of something else... I have 1.6 ratio roller rockers, I'm not sure if I have reliefs cut into my piston heads for the kind of valve lift I want on a new cam. Is there a way to look up the head specs without removing it since I can not do it myself and cant contact the original owner anymore? Or should I stick with the purple shaft and hyd flat tappet with the roller rockers so I dont destroy my valves? This is the most confusing part of the freakin motor?!?!?
