Larry, one of our research facilities in Europe measured bore distortion on a running engine that ran at 6,000 rpm. SAE Paper 2002-01-0485 has the results of the testing. It makes for an interesting read.

Re: Dumbo The Flying Elephant
 

Thanks Greg, I will read it then I will get Chris to understand it for me.

We wanted to tweak our ring package just a little, so I called Total Seal for the rings. A pleasant surprise was everything was on the shelf and it will be shipped today.

I may try a Bob Gliden and build it without the aid of an engine stand.

Stan, I always want the car better than 50/50 and rear weight biased enough to have the car go straight in a wheel stand. The iron head engine makes more power than the aluminum heads , but the aluminum heads go A to B much more consistent.

Re: Dumbo The Flying Elephant
 

In going through some old information I discovered a torque sequence for the main caps. After following directions I rechecked housing bore and it was good.

Bob Toy finished rewiring the pink car and it looks organized and easy to work on. Still have to scale car and test.

Re: Dumbo The Flying Elephant
 

Iron head engine has lower hp rating ie lighter weight ? Why not fix the car to go straight and consistent?

Re: Dumbo The Flying Elephant
 

Glenn the iron head engine makes more power and is rated higher.

Re: Dumbo The Flying Elephant
 

NCAA basketball is over until Thursday. I will be able to see the relationship between the deck plates and the heads as to how round and straight the cylinders are.

Re: Dumbo The Flying Elephant
 

The plates and the heads are real close, only a few tenths difference.

Better equipment = better results only if the operator is skilled and experienced. Jeff Taylor Performance is such a place. I went there with the liners everywhere, over .002 variation in places, the end result was the cylinders were round and straight and only .001 bigger. I got one more build or of my pistons.

I miss a lot from my youth, I’m sure everyone can come up with a punch line, but I miss my eye sight the most. After cleaning and inspection I decided to reuse the main bearings. I caught the light just right and the saw a piece of trash on the bearing that would not wipe clean. The bearing was starting to flake off. That would have been pretty after a few dyno pulls.

Re: Dumbo The Flying Elephant
 

Is it a Polymer coating that was flaking? If so why did you re-use it?

Re: Dumbo The Flying Elephant
 

It was the Babbit flaking

Re: Dumbo The Flying Elephant
 

I think I'm done!

Re: Dumbo The Flying Elephant
 

Have you tried ACL or Clevite bearings?
I know there are many that have not experienced issues with King bearings and will vouch for them.
Due to the issues, others and I have experienced with King bearings, I have not used them since 2017. My "to go" bearings are ACL, Clevite, and when I can find them, Speed Pro. In 2017, we had issues with several Trophy Truck engines with King Bearings. Switched to Clevite and ACL and no more issues.

The pictures below are issues that some other engine builders have experienced with King bearings:

Re: Dumbo The Flying Elephant
 

Thanks. It looks like plenty of end gap on the lower ring in the cylinder on pic number 4.

Re: Dumbo The Flying Elephant
 

With the exception of one gage acting a little funny, we don’t know why, Bob Toy did a perfect job of rewiring the pink car. Everything worked the first time after we found a defective part or two.

Thanks Bob Toy

Re: Dumbo The Flying Elephant
 

We finally got to go down the track with the pink car, after a trans change, rewiring, scaling, and suspension components change. Everything worked as advertised. We are ready to go racing!

Re: Dumbo The Flying Elephant
 

Awesome Larry glad Pinky is up and running smoothly ! where's your 1st race outing ?

Re: Dumbo The Flying Elephant
 

Got my gage back from Classic yesterday. I will plug it in and bolt it up, it should take less than 5 min.

We will be going to St. Louis for the Class Racer Revival next week, for the money you can't beat it. You can enter at the gate.

We get to be back on Dumbo's engine today.

Re: Dumbo The Flying Elephant
 

Parts are a problem. It took forever to get them and then a while to get to fit. My elephant engine is a little picky on what it likes.
I had time to check the correlation between the torque plates and the heads, not perfect but pretty darn close. I got the main bearing clearance variation to .0003. I'm happy with that.

Fitting rings today. That means mains are torqued, honing plates are on, and get to use my present from Santa, my Total Seal ring filer. With a little practice removing .001 from the end gap is easy and predictable.

Re: Dumbo The Flying Elephant
 

Starting on a new block for Dumbo. I have to check bunch of stuff, remove sharp edges, and remove all of those little shavings. Went to order a new stud for oil pickup mounting 14 to 15 weeks out if I’m lucky. I know I have a few hidden in some bar stock, I just have to find them.

Re: Dumbo The Flying Elephant
 

Larry,
You're living every class racers dream and I know you appreciate it.

Re: Dumbo The Flying Elephant
 

Before I have to quit it would be kool to have a pro built engine instead of my backyardagens

Re: Dumbo The Flying Elephant
 

Ran across this on facecrack.⁷

Re: Dumbo The Flying Elephant
 

I have never seen that one. Thanks

I wonder what I was watching.

Re: Dumbo The Flying Elephant
 

Showing my age. I was asking a few vendors if they had any aluminum Gen 3 Hemi blocks, for a racer in need. The representative said he never knew that MOPAR made a Gen 3 Hemi aluminum block, but he will check and get back with me.

Got interviewed today about the race but I don’t think it was for local television.

Re: Dumbo The Flying Elephant
 

Another dry hole for us Gen 3 racers no support.

Re: Dumbo The Flying Elephant
 

It’s time to do the heads. It’s takes me forever to get to the numbers .XXX” from coil bind.

Re: Dumbo The Flying Elephant
 

Larry, you probably already know this but I will say it anyway. My aluminum block came from Arrow Racing Engines. I don't think it's called that now since Lee Carducci retired and they may have gotten rid of all of their blocks. Just a thought.. Wanted to pass it on.... Phone number I have (248) 852-5151......

Re: Dumbo The Flying Elephant
 

A lot of the Arrow Racing assets also went to Prefix.

Re: Dumbo The Flying Elephant
 

Arrow is know known as Prefix (248-650-1330)

https://www.prefix.com/performance/#Parts

They show the block as sold out.

There are three blocks, Larry do you know which one you need?

Part Finished Max. Bore Crank Cam
Number Bore Bore Honed Honed Bore
P5153897 4.055 4.060 Yes Yes Std.
P5153898 4.114 4.185 No Yes Std.
P5155507 4.125 4.155 Yes Yes Std.

Re: Dumbo The Flying Elephant
 

Didn't the Don Schumacher team have a sh_t ton of those blocks?

Re: Dumbo The Flying Elephant
 

How about the Southland/Tueton group?

Re: Dumbo The Flying Elephant
 

I use the 898 block

Re: Dumbo The Flying Elephant
 

I wonder how much power it will make with a block that wi ll stay still.

Re: Dumbo The Flying Elephant
 

There is a reason why pro stock still uses a cast iron or graphite block.

Re: Dumbo The Flying Elephant
 

Glenn,
Does Weston Machine in Piscataway NJ still do many of the Pro Stock team's block preparation?

Re: Dumbo The Flying Elephant
 

Stupid old man trick bent some valves. And I just did that a few months ago due to a part failure. Like they say if you’re going to be stupid you got to be tough

Re: Dumbo The Flying Elephant
 

I don't think so. With cnc machines anyone can do it today.

Re: Dumbo The Flying Elephant
 

Had enough parts so it will be back together today.

Re: Dumbo The Flying Elephant
 

Have you posted any pics of the new car or did I miss them?

Re: Dumbo The Flying Elephant
 

Just buying parts, doing a little research, and getting my block honed with a new ring or two.

Re: Dumbo The Flying Elephant
 

I am not sure Larry has ever posted a photo.

Here is one from Auto Imagery
