The bumpstick. Solid roller. I don't want to give the specs. Lift somewhere between .6-.800", duration between 260-280. Lobe separation is 110, 106 centerline.

at .050??!! GADZOOKS! :o


I wouldn't run something that small, advertised.  ;D

Beautiful work Jared, your attention to detail really shows.  I'm sure it will all pay off with a very strong engine.  Do you plan to dyno this one?  Street and strip, or strip only?


Thanks Jay. I don't think I will dyno this one. It will be street n strip. The track is an excellent dyno....

Thanks John. Maybe you want to rethink the stroker route this time, and do something like this.....

Haha, Jared, it’s very tempting.....I’m not the most engine savvy guy, but something tells me your unspecified solid roller and 12.5 compression would not be user friendly with my desire for power brakes!!  ;D ;D Yea, I’m one of those guys.  ::)

Hi Jared,
Not to take away from this build, but I saw on one of your other posts you had made up some steel shim plates for your rocker stands. I may need to do the same. Was that just mild steel that you used, or something fancy? I take it you just traced out the footprint of your rocker assembly?

Thanks,
Mike

No problem, Mike. I didn't go fancy on those shims. I figured if the stands were aluminum, even a strong grade, then mild steel should suffice. I just went to my local store and got some 1/4" thick flat stock. I bolted the rocker stands down and took an overall measurement and cut to length. Then I measured for bolt hole locations and drilled them out. Then I marked where the head studs would interfere and marked locations to notch for valvesprings. I did trace the inside of the end stands to clearance for the head studs. Then I made sure I trued the faces and got my desired thickness.

These pics are of iteration 1 of this build(RIP)
