My Long Block Build is Complete!

Thanks. What tool do I use to measure preload? Can you explain it again a little more specific. I kinda understand it and yet i'm kinda confused. TIA
Do you think it is possible that after they did their measurements that they got the specs of a stock pushrod? Or is their no way in hell? This I want to know. Thanks

That could happen if the base circle of the cam wasn't changed during the re-grind, but is highly unlikely with lobe modification.

Easy test, put the lifter on the base of the lobe (no lift) and install a pushrod. See how much preload you get (tighten the rocker till the pushrod just spin, no slop, and anything past that is preload).

You're a dick.

Hey no hard feelings, just pulling your soon to be stretched chain.

that is definately different that they came up with the same length pushrods as factory

Why yes, yes I do! lol

You're a dick.

Back on topic, I took one exhaust and intake pushrod off of the new engine and compared it to my stock pushrods and they are they identical to stock.

I just got off the phone with the machine shop and they said that they didn't even have the specs for the stock pushrods. They said they took the geometry from the cam, headgasket, and something else and thats how they came up with those specs. Is that possible even after taking all of those pics to come up with stock specs?

Also, someone tell me how I find the pushrod length out for myself; without having the machine shop remeasure everything again?

Why yes, yes I do! lol

[blackbombshell95]

You think that is pretty funny huh

[blackbombshell95]

through the machine shop. I'm going to compare them to a stock one tomorrow. Maybe it was a misprint because I told him to get the proper measurements.

[JMo60]

where did you get your pushrods??

[sprucegagt]

LMAO

Yup, they listed the stock length pushrods for your custom pushrods.

[blackbombshell95]

Ok, going over your receipts, there are a couple things. Those pushrods are stock length. Not a good thing. Also, oil is too thick, use a 5w30 and that comp additive isn't needed. It is only for flat tappet cams, and yours is roller.

Are you sure those pushrods are stock length?
