Lifter Blocks.....

Can you use Evo lifter blocks and lifters in a 77, 74" shovel motor? If you can, what pushrods would I be able to use? Thanx.....

Your going to go that route look into Jim's or S&S shovel lifters, also Vulcan has updated hydraulics that use the stock shovel lifter blocks or complete kits.

At this point do I still use the shovel cam or do I upgrade the cam to an Evo cam? Thanx......

I ran one of those and the Jims lifters in my 88" shovel and it was quieter than most evos.

That's where a lot of valvetrain noise and performance issues comes from mismatched cam & lifter profiles. Run a hyd. cam with solid lifters it beats hell out of the lifter and it's noisy, hyd. lifters with a solids cam and you take a performance hit in lift and duration loss.

Roller rocker arms you need to pay attention to clearances inside the rocker covers

I installed the Jim's kit a few years back and my 82 is really quiet. You get evo style lifters and matched pushrods and everything just drops right in the stock blocks. The jims lifters have an evo style cup in the lifter so you have to use their pushrods. Really a nice improvement. Part#2411.
