More than likely that target is going to grow and may grow some more. The last e-mail he sent to me he was looking for investors to buy into the deal as he either didn't have the money necessary or was not willing to spend more of his own. How about it out there? It can't be any worse than the stock market or the measly 3% at the bank. Or can it? If all the bugs were worked out (and there WILL be bugs) I might invest or handle the machine work. Once the scrap rate and all the work involved are actually performed and worked out the price may rise rapidly because I can assure you that foundries will not eat very many scraps or do a lot of work without a price to go with it, especially a quality foundry, ISO 9000. If you don't agree you'll be asked to move on. Been there and done that. Moreover, all of us with machining capability and machines do our best to estimate the time but sometimes it takes more than orginally thought, so the price goes up accordingly. Larry B.

Re: NEW A Engine
I said "...75-80 HP..."
Yes, the HP is relatively easy to achieve. How about sustained reliable operation at 3500 RPM? I have a counterbalanced crank and well-balanced reciprocating parts and flywheel, but I shudder to think of taking my engine to 3500 RPM and staying there, as for instance on the freeway for hours. What's your take on maximum sustained RPM for a stock-block, balanced A engine, Larry? Thanks. Joe

Re: NEW A Engine
Joe, line 'em up and ask how many will rev their Model A's up in the 3500 RPM range and the corresponding road speed that goes with it in high gear. Most won't do it even if you prove to them that the engine will stand it.

How many of the 30 have 'five mains' and a 'new modern tech crank/rods,etc'. I figure that my current NOS B block, with all the trick stuff...is making 80+. I figure when I put similar or better stuff onto new stronger modern tech 5 main block. Well, I'm getting at least two..can not wait!! Rick |

Having made Foundry castings for almost 30 years, it is fairly easy to I.D. the type of foundry sand, binders, and additives from the surface finish of the casting, both the external "green sand" mold surfaces and the cored surfaces. The preliminary photos I received from Terry (New Engine Update Email) show many issues still to be addressed. Visible are shifts, green sand breakouts, and penetration/ sand burn/in, all to be addressed before production. Even with the proper additives and washes to the chem set cores and synthetic green sand mix used by the Lodi foundry, it will never be possible to get a perfect match to my eyes. The collective sieve grain distribution of the sand used by the Rouge and Lodi will never match, nor will the surface "peel" effected by organic sand additives at the Rouge (wood flour, molasses) and the modern adds at Lodi. It may be close to some eyes, coverable with a heavy two coat paint job (over-restored???), and will look perfect in the average "A", but wether or not it prompts changes to the J.S. to look for specific clues remains to be seen. At the rate the standards are revised, you will probably be safe 'till 2025. But not to my eyes, ever. Would I want a Burtz block? Heck yea, but under one of my Yapp/ Rileys for 150 H.P., not in my J.S. correct (well, sort of) roadster. Depending on the grade of iron Terry Burtz specs, you may be able to redrill the block and your heads for 1/2" ARP or aircraft head studs and crank 100+ foot pounds on them. That may help keep the head gasket under some high power heads and engines. |

I've not received one of his e-mails in quite awhile and have seen no pictures. Are you sure that it's green sand? I hope he didn't use green sand. Modern green sand castings have a different look all together. They are generally not very smooth in my opinion. Moreover, people not familiar with foundry work don't realize how sensitive molten iron is as far as transferring the smallest details (texture of the particular sand used, etc.) to the casting. Many people seem to think the molten iron is about like lava when it flows. Not so. It's about like water as it flows and will transfer the slightest detail! So the end result will be a casting that will work as intended, but it may be real easy to tell them from the original. Moreover, not only will "shift," "burn in," etc. have to be controlled before production, there may also be other surprises that won't show up until machining, such as shrink tears for example. They may even show up intermittently! As I said there will be bugs. It's not easy to cast water jacketed parts with internal cores and many foundries want no part of it. I hope Lodi has considerable previous experience with large parts of this nature because they're going to need it. Larry B. |

Re: NEW A Engine
In John LaVoy's magazine, Model A Times, there's the article about the new Model A engine. Very well done and very interesting. I'm looking forward to seeing on of these new engines

Re: NEW A Engine
3,500 RPM in my AA with a 5:14 rearend sould be legal freeway speed.

Re: NEW A Engine
Terry brought the engine to the last meeting of the Santa Clara Valley Chapter. I was impressed. The crankshaft is heavy, 5 large diameter main bearings with massive caps. The bottom end of this engine will not flex around like a stock A or B. The intake ports are 45 degrees to the larger intake valves instead of 2, 90 degree turns. Breathing will be better than any stock block could ever be. Of course if you put an overhead on it that will not matter. But it should be capable of high rpms without risking ruination, and it should be smooooth running.

When I saw the block, crank, and rods at the Turlock meet in January I was told the price was $3,000.00.

Re: NEW A Engine
Chris, I'm assuming bearing inserts. Do you know what the oiling will be, pressure fewd or the current 'original' 'A oiling?
Regards Mike. |

The block was their first casting. It was machined but for all intents and purposes it was worthless because of some casting flaws. The crank and rods were also finished. The rod caps are on an angle to the rod to allow for clearance between the boss for the rod bolts and the cam.

Re: NEW A Engine
Just a note for those interested in Terry's new engine.
Terry will be holding a Technical seminar on Thursday afternoon at the 2011 MARC National Meet in San Diego, June 27th to July 1st. He hopes to have a complete unit to show the folks. Registration forms for the Meet are in the Jan-Feb edition of the Model A News. Hope to see you there. Dick |
