Re: Engine
A tour engine usually has a higher compression head and a regrind cam [ or new kinds 3/4 grind]
Rebuilding would probably depend on where you are. |

Re: Engine
This is a whole debate with babbit vs inserts and personal opinions. Let me offer you this. Babbit is a little more tougher than inserts but is a big problem to replace if something goes wrong. Inserts are much more easy. Every modern engine since the 50s for the most part has had inserts, even before that too. Babbitt also takes somebody that has the tooling, equipment, and knowledge to do it. Inserts are easier to install.
In Northern Illinois we have Antique Engine Rebuilding. Rich has been doing it for over 30 years and does 100 to 150 engines a year for people all over of the country. He knows what he is doing and uses inserts. There are other places but personally I like them and I would not use babbit anymore because it is very hard to find somebody that truly knows how to properly do it. Btw, a touring engine usually has the aforementioned hotter camshaft and high compression head, but also larger intake valves and bores to suck more air. I do believe they also have a lightened flyweel and sometimes a counterbalanced crank. Depends what you want to do with your car. You can go faster and have less take off time from a stop.

Re: Engine
Schwalm's is in eastern Pennsylvania. Closer to Charles Town than Charleston, though!

Re: Engine
I was told several yrs ago that Schwalms is an xlnt engine rebuilder and that they only use 1 in 4 engine blocks, as the blocks are often shot.
on another thread currently running- it is mentioned that Berts only uses 1 in 12 engine blocks......... so there are various builders with various requirements. do your due diligence. A complete touring engine is not inexpensive. |

Re: Engine
Consider the Terry Burtz engine. This is a new Model A engine with a modern bottom end.

Also, I have experienced several situations where the inserts were worn enough that before the driver could catch it, the bearing rotated in the main cap. When this happens, it will distort the cap. The proper way to correct this is to grind the cap and line-bore the block again. This generally means the pan rails and the main web needs to be surfaced by about 0.0005"-0.001" to make all the mains round again. Then the boring bar set-up must be changed to make sure the timing gear lash is not too tight. So while the inserts can seem easier to do on the front side, there can be stress involved in redoing that conversion too. And for what its worth, there are plenty of quality craftsmen that can still cast bearings. The longevity is generally longer when the cast bearing is done correctly, however many hobbyists just want something done that will last them until they are done and then the next owner can "cleanup the mess" if something goes wrong. |

Debating between babbit vs inserts is like comparing apples to oranges. They are different and both have pros and cons as you know. I will say that if they are both done properly by somebody like you then they will last a long time. Seems we only here about the bad craftsmen though!
