I use Vaseline on everything like the loose bearings when I assemble. also use it when packing internal engine bearings. I learned this as a professional engine builder at S&S Cycle. I have some of the very good Mobile 1 assembly lube they make. Since I only have a couple bottles left I have that mixed with STP for heavier stuff where I want lube to be retained over a period of time when I can't put the Vaseline in a spot.
Thanks Steve and Ted , thats the info I was looking for , with the tips you guys threw in , it makes this mod . alot more easier . It Seemed pretty straight forward , now with your info I have more confidence. I feel having an engine built by the gurus is great , but I am more interested in having the knowledge to do the stuff myself. So please excuse me in the future with all the questions as I appreciate learning from you guys that have been there and done that.
Ya know, there's something satisfying about the West Bends once properly set up, they're as tough as toenails. I like being different. Back in the late sixties, while everybody else was running Bowties, I ran Mopars. While everyone else had a small block Chevy in their street roadsters, I had a 330 inch Olds. Pop's Deuce roadster had a 475 inch OHV V-12 Cadillac in it. I wish I had THAT engine back! TJ
Funny you say that Ted . I was in my mid 20s and ran a 461 olds ,now a stroked 488 ,at the dragstrip . I ran with a bunch of 50- 60 year old guys that I met through painting thier cars. They all ran 540, 555 BB Chevy motors in thier cars and would invite me to run when they rented Norwalk , everyone kicked in 40 bucks and we would have the track for 4 hours. I showed up with my then primered 69 olds 442 clone with a 6 inch cowl I grafted in a 70 f85 hood because it was flat. They always gave me hell for running an olds engine, saying the only way they go fast is if you drop the engine down a mine shaft. I remember launching that thing and it squated and yanked the tires off the ground , running 11.40s with stock olds cast steel heads ,full exhaust on 10inch cheater slicks. Not the fastest time really , but they didnt dog the Olds after that ,even though they ran 9s , lol. I honestly had 4k in my olds ,was mostly stock. Chevy has better heads , cheaper parts , more plentiful . But there is something to say for the odd drag race engines like B.O.P. , they had tons of torque out of the box , heads were not the best design though. My buddies father was a roundy round engine guru and taught my buddy well how to build an engine and tune it , he tuned my car needless to say , taught me alot. Some of my best memories were when the track got rented by the ole timers.

My '60 Sport Fury ended up with a long ram 413 "Sonoramic Commando" with reworked heads, factory monster tube headers and an Ed Giovanoni quarter speed roller cam. I drove it to work every day and finally  let it go for a '65 Sport Fury. The '65 was nice, but never the car the '60 was! The attached pic isn't my car, but is identical. All my albums were stolen in the mid sixties. Ted
Ted, I may put together a kit with the proper spacers for sale to anyone. I just did a video last night of the procedure so in the next few weeks we'll get that ready to post. It is really the only part of a WB engine build that is out of the ordinary. This will help those at home with the method needed to do this.

Steve, sounds like a good idea. Have you measured a number of pistons between the bosses to be sure that all spacer thicknesses would be the same? I know the Wiseco 610 piston I'm currently running is a bit different from the Chrysler 610 pistons I have here. I'd think a few procedure photos or illustration drawings would help some of the guys to do the bearing grind and to put things together right. The kit just might save a few good engines! Ted
The spacers will come oversize in thickness. This is why I have done a video. You can see the entire procedure first hand. It explains how you get the spacers sized down. A very easy process. Yes some applications may require something different. I am aiming this at the 820 and the single groove piston at this time. I also go into detail on what rods are good rods and bad. It will be pretty straight forward when you see it. No hidden tricks. In time the Macs will go away so people need to understand this engine.
Great to hear Steve , thanks for the video.
Question ,I know the saying "why fix it if it isnt broke" , but I was curious if anyone tried graphite coated thrust washers for the loose bearing mod?
