update on rhoads variable lifters
 

well i installed them..they increased my vacuum by 2 inches...smoothed out the idle some..not much...(if any) performance increase..the noise is very much like solid lifters...i think ill have to recalibrate the carb now, because of the vacuum increase

I think the whole point of them is to be able to run a wilder cam, but get it to idle on the street. So the lifters themselves don't give a direct performance increase, just an indirect one.

Never having had an engine with these in them, I will shut up now http://67-72chevytrucks.com/board/ubbhtml/smile.gif

I've always wondered how you adjust valve last when the lifter is only partially "pumped up" (i.e. Rhodes lifter)?
Anyone know?
Thanks.

I have them, still don't quite understand them, nor if the claimed benifit is true. They were there when I got the engine.
So I to, will shut up. http://67-72chevytrucks.com/board/ubbhtml/wink.gif

Need to pick up the one ton Longhorn with a PONTIAC 350/350soon.

to adjust the lifters....when u install them u have to fill the lifter by submerging them in oil and "pump" them up with a screw driver, then when u install them, u compress the plunger 1/16 of an inch..u dont make any further adjustments
