I went and picked up the rotating assembly from the shop that balanced it today, the crank took 4 mallory(spelling) slugs total, 2 in each end. Total cost on the balancing was 300 bucks, thats the cheapest I ever heard of one being done for, bout time I got a break on something with this build.
The guy that does my block machining said these things are too pretty to put in a motor. They are a thing of beauty....
and finally the rods...I almost passed out when I found out what those Carr titanium bolts cost...of course Lentz rods aren't cheapos either.
can i ask how much the set was? i'm looking to get some rods and a crank soon. i'm already collecting parts ahead of time just incase my motor blows up soon!
Sweet $300 to balance a crank seems really cheap, I have heard that the Mallory slugs are $50 a piece.
That sent up a red flag for me when he told me the price, I spent almost 600 to have the one in the street Mav done,so I asked to speak to the machinist that did it. He said the cost runs in direct proportion to the quality of the components he's working with, better quality=less time and material. I was charged for 2 1/2 hours labor and 2 -7/8ths x 1 mallory slugs and 2-1x1 inch mallory slugs. Mallory can run as high as 75 dollars a slug depending on size and weight, mine were a little less than 40 each.
Cost to Balance The shop that did my rotating assembly charged me $300. The guy said balance jobs usually run around $175 or so depending on time. With my lightweight pistons and rods they drilled out the counterweights till they looked like swiss cheese, it took almost twice as long (5 hours) to balance. $600 is kinda ridiculous.
The labor rate is 60 an hour, apparently your shop has a lower labor rate or didn't use any mallory, but I'm at there mercy as there the only shop that does it around here that I'm aware of. The shop also requires the rods, pistons and harmonic balancer when they do it. Very little drilling was done on the counterweights. The 600 dollar crank job took 7 pieces if heavy metal and no drilling on the counterweights.
Rick all makes sense to me. Looks like they did a good job! I assume the pictures of the pistons and rods were taken prior to the balance work being completed
That's because yours was externally balanced and Ricks is internally balanced, which is a much better way to do it and a much more expen$ive way to do it. Rick, I thought those metal slugs were supposed to be welded/brazed in so they won't come out at high RPM's ???
The added metal doesn't need to be brazed if it's in the side of the counterweight. If it's in the end then they stake or braze it.
