Dumbo The Flying Elephant

Did you also order a set of King's? You may be surprised at the difference. I won't say that they are the cat's meow, but I like what I see when stuff comes in for freshen ups. The Clevite's are probably good enough for 85% (or more) of the engines out there, but I usually see better consistency with King, and sometimes ACL, depending on application.

I have two CB 663's and one set of ACL so I should be able to get something to work. If not I will get a set of Kings

Got the pink car running yesterday after it being rewired and with all new Classic Instruments gages. I think we solved the occasional no start problem, a bad fuse block. For some reason I had another one on the shelf.

100 percent correct on King bearings

Got the honing plates on Dumbo with the crank still in the block to check cylinder straightness. Bottom line is we have to do something different, the cylinders were everywhere. .002 tight at 2-8 o’clock,10-4 slightly better, 12-6 loose tight loose, and 3-9 not bad.

I should have quit a little over a year after we started racing, because then I knew most of the answers!

Hey Larry, was the block sonic tested before using. The cylinder wall thickness is thin to begin with.

I believe that Larry has the Mopar aluminum block. I have had friends that faced the same problems. You can try to hone it straight, but after you run it, the dimensions are all over the place. 8 Darton sleeves would be the place to begin or take a 100 lb weight penalty and use the cast iron BGE block.

As Dyno stated, sleeve it.
The best is Steve Demirjian at Racing Engine Development in California.
He is also the Engine Shop Manager of Darton and one of the foremost experts in sleeving blocks holding many patents on engine sleeves.

In my opinion another expert in sleeving and cylinder wall finish is Brad Lagman at QMP Racing.

Hidden Horsepower episode on cylinder honing.



However last time a checked and it is probably worse now, he had a thirteen week backlog on block work.

Sorry to side track the thread, but is it legal to use the BGE in place of the MP Aluminum block? I did not see anything listed on NHRA accecpted products or 2015 Blueprint page regarding the BGE block.
