hi first post here. I have a 02 dyna lowrider with a 124". its got thewoods cams forget the number but its 678 lift 268 duration i think, its a strong runner and usually bring it to 6500-6750 rpm. i dont think i have any valve float. Im running s&s steel pushrods with comp springs again forget the numbers. the intake valves are 2.250 and 1.750 for the ex. i guess my ? is can i benefit from aluminum pushrods since these valves are fairly heavy and it revs pretty good. just lookin for a little more insurance by saving some weight . or is aluminum not strong enough to handle the pretty high spring pressure and rpm. i know the ? is a little vague and if you guys need the specs on the springs and other things i will dig them up . thanks for any info you can provide about aluminum pushrod reliability.
