I am wondering what the differences in the heads between a dynatard E6 4 valve and non dynatard e6 4 valve? My 1987 R688ST has a late '86 4 valve E6-350 with non dynatard heads and was wondering what it takes to make them accept dynatard components. I thought I had read the exh valve seat depth was deeper and the push rods are different. I would like to clarify that prior to having the machine shop go through my non Dynatard heads. Any help would be greatly appreciated. Thank you.

Get well Mike.

Thanks for all the info guys. Much appreciated.

Thanks for the response. I was thinking that a 3 or 5 ton hoist would be sufficient. I am going that route vs the loader, as I want a bit more control over what is going on and I can keep it in the shop. The trans is an 18speed quadruplex.

Good morning guys. I am in the process of removing the engine and trans from my B73. As they were both working fine, I was thinking of pulling them both out together, and not separating them. Can anyone give me a rough weight estimate? I would like to try a manual chain hoist instead of the payloader. Thinking of purchasing a 5 ton chain hoist for this project. Just trying to figure out if this has been done by anyone before, or if I should not attempt to do it together. I want to get them out in order to scrape off 50 years of grease on the frame before a good sandblasting and repaint. Then the goal is to clean up the engine and trans, paint and reinstall into the frame. Thanks for any input.

very nice. Little rust.

Made a trip down to Illinios to look at a cab. My luck, found 2 that were in good shape. Met a great Mack guy named Bill that made me an offer on both I couldnt refuse to take for them both. With a title and power steering assist assembly to boot. Loaded em up on Saturday morning and were back home on the farm by noon. Lost a little rust on the highway trip home, but no issues with Johnny FunWrecker. Bill was a great help and had alots of the Mack parts I needed. These two pieces will come in handy for the restoration of my other ones. He had just sold his 1920 AC Mack a couple of days before I got there. That was also neat to see. The old shovel he used to load the 2nd cab was also cool. Thought I would share some pics.
