GH,
None of the old Buick books list any bearing widths until the 1953 manual, and then only the V-8 at .881. Glad to see it's coming together. Did the rod stop on the crank and break, or did the piston stop in the cyl and fold up the rod? From the pics, I couldn't tell if there were score marks on the piston.

Glad to hear it's not worse than it is. I don't mind blowing one up on the salt. I would hate it on the dyno.

We think it was an oiling problem. We added an oil filter and the fittings going to and from the filter was 3/8" pipe threads, pretty small on the ID, quite smaller than the main oil galley. It looks like the rod bearing seized on the crank and pulled the rod bolts out. Rich, we think it was better to have happened on the dyno than running across the salt and have it lock up, no telling what would have happened. On the data logs the rpm went from 2200 to 0 in less than a second.

If in doubt, it probably IS a mistake.

Let's hope that's the fix. Hate to be a pest, but we love your pics.
I remember commenting on those rods - They looked pretty stout, and I didn't think you were winding it tight enough on the dyno for a rod to let go on its own accord.
Best wishes.
Chris

[/quote]On the vido I thought the rear wheels kept spinning being pushed by the roller. I saw the blower stop. I blew one Plymouth way worse than that at El Mirage, and it kept running until the crank snout wiggled around enough that the fuel pump drive belt came off.

I was off the gas, in gear when it started to let go (so yes, being pushed by the rollers) but as soon as I heard the sound of "ice going through a giant blender" I clutched it. was too late by then, of course. |

Just found out Friday that the rod bearings are the same width for all 3 sizes of the Buick straight eights. Now we can find out if the crank will clean up at one of the bearing diameters, then we can order the rods. The rods might beat us home from speedweek, hope hope....

Mike just received the new rods from GRP, now we can get back to putting the engine together. We still have to figure out the induction problems we had. Too much area by using the throttle body we had, just crack it open and the rpm went way up, it would be very hard to drive.

Glad you got the parts in, but it is regrettable that they didn't arrive in time to sort it all out for WF. Thanks for keeping us posted on this, and good luck with the induction - you're certainly not taking the the path of least resistance.  |

Good article on creating start up/base line set ups for EFI systems in the latest [Fall] Engine Masters magazine. Might find some information in it that would help you.
Available in my area off the rack at local supermarkets or Barnes and Noble. My copy is currently out on loan and probably won't be back for a week or so otherwise I would look into it again as it might apply to your problem.

MIke took all the pieces out to be balanced yesterday. On the throttle body problem, we had thought about using an Enderle hat on top of the blower with the efi injecters in it. A bug catcher would have smaller openings than the throttle body we now have. Ours have an area of 30 square inches.

we're pretty sure there wasn't any issue with the EFI. |

Well, a lot of time has past since the last post on the Buick rebuild. Mike has been extra busy (he still works), but we are getting ready to start the assembly. I think we have finalized what we are going to do with the induction. Purchase an Enderle bug catcher and set it on top of the other throttle body we used last year that has the injectors in it and remove the two rectangle butterflys.
