I hope he gets this engine done and can sell them at an affordable cost. I am a little puzzled at the difficulty in getting good block castings. Maybe a look back at old technolgy would be in order, after all Ford was able to make a bunch of these.
I'm new to this forum and came across this five main question. I can understand the need for a reproduced Model A block but I get a giggle out of the 5 mains. I take it that you guys haven't been able to get the correct babbit. I've seen over the years engine shops have tried turning down the mains to put in bearing inserts only to weaken and have the crankshaft break. So it's now trying to make a five main to correct the problem. Not a bad idea but cost is going to be out of this world.

Yo, Ford1931, ridicule of Terry Burtz is Not in order. He's doing this WITHOUT multi-million $$$ backing, and is striving for a REALLY good product. Do a search on progress & pics of castings, etc, & you will be impressed! Bill W.I hope he gets this engine done and can sell them at an affordable cost.

. . . Most babbit used now a days by these engine builders are marine babbit with extra lead thrown in. That's why some of these newly rebuilt engines are coming back pounding. Maybe this has changed in the pasted couple of years but I doubt it. . .
Just to give some insight on Terry. He is, or was, an engineer in the aerospace industry. He has owned and restored Model As all of his life. When he retired he went to work on the design of a modern engine that had the outward appearance of a stock Model A. This was not for production, just something to keep his mind busy after retirement. After working on it for awhile he decided to see if it could actually be build for a reasonable cost. Because this is beind done as a labor of love and not a money making project the engines will be very affordable, especially if you compare them to the Donovan engines. Terry isn't charging the project for his engineering or time spent making the molds etc. He does all that out of pocket and travels back and forth to the foundry to examine castings and talk to the production people.
I know people are anxious to get an engine from him, but he is not going to release anything until he has worked all the bugs out of the process. I have known Terry for 40 years and know that he, if anyone, can bring this engine to the hobby. But I also know that he won't rush it, he feels very firm about it being engineer driven not cost driven. So when it does come out he feels very confident that it will hold up for the next 80 years of Model A driving!
But I'm right there in line to get mine, so come on Terrry get this project moving! LOL
I have one of the more recent castings in my garage and have posted pictures so you can see the process that has been made.
