HEY,guys what length push rod was used in a stock 340.if anyone has apart number ?thanks for info
 
same as a 318. 7.534. All hydro LA's were the same pushrod except the T/A that used ball and cup on a hydro lifter.
 
can't vouch for the accuracy of this chart:

How much is the pushrod preload?
Or how much is available?
I wonder if there is a difference in the regular Hyd. and the Hyd. roller tappet.

Silly, disrespectful and smartass. But it fits "these days" alright. Someone comes for help and gets "Let me google that for you". Some people like more interaction than frikkin google.

Rusty, give credit where credit is due, I said it first :lol: Just trying to keep things lite.
In the IT business we use RTFM "Read The F++king Manual"
The parts sites are great reference also...Summit, Jegs, Rockauto ect
 
The bigger question is why would anyone care what length the stock pushrod is? It's not like anyone is gonna actually go out and buy new pushrods based on some 50 year old number that might or might not actually properly fit an engine that's been rebuilt 5 times and most likely uses different ball/cup sizes and rocker seats.

Surely, no one would do that, would they?
 
Yea, they do. Is amazing but often, they still fit.

I get people asking how the new printer I just set up for them works, and I hand them the instruction book and they say “I don’t want to read all that”.

Then I ask them if they want me to charge them the time to read it, and then explain it to them.:D
 
I feel your pain...but it also speaks to the simple truth that a person can explain something in 5 minutes that an instruction manual can explain, somewhat, in 4 hours.

When you visit Hell, and you descend below the floor for murderers, then go past the floor for child molesters, then go a few floors further down, you arrive at the floors for people who write instruction manuals.

Yup, I just built a 340 with hyd lifters and Comp Ultra Pro magnum adj rockers. Stock p/r length is 7.500. Put in Comp magnum p/r 7.500. Exact same legnth. Changed them bc the springs are 310 lbs open. Kim

The irony is, if you google the question now they will bring you right here for the exact answer.
