These are the first 3 sample castings I had made to try my hand at slightly lower compression ratio than my specialty heads, like the Winfield (6 and 7:1), Weiand (6 and 7:1), and Stock Top Crow Foot (8:1). I will make some of these, but I do not imagine there will be an extensive market. I do...

As I peck away at this Weiand-style head over the next few weeks/months I'd like to get a feel for how many castings I will need to order for the first run. Let me know if you are interested in a 7:1, 8:1, or 9:1. I think the first run will be aluminum only. 7:1 will be the crow foot...

Since the first aluminum OHV head tested beyond expectations, an iron version is being pecked away at as time permits so it can be tested soon. I need to get cracking on these, as I have a dozen people wanting one, including some overseas customers. Tod

Just about there on the first OHV build. Not my build, just the first aluminum OHV head. Tod

The 3rd sample casting proved even better than the first 2, which are in the hands of builders. I made 4 more prototypes and here is the first one of those machined. These are around 7:1 (just a bit over). Tod

Today I took time to assemble 4 more molds for the new Stock Top Crow Foot 7:1 cylinder heads. The first 2 samples are in the hands of builders who will be testing them, although the chamber has been tested as the B head already. I also am making a couple dozen more Winfield heads, both 6:1...

Back in December I asked about a cylinder head that turned out to be a Miller head, and not a Winfield as was believed. Since then I went to where this head was and took some info from it and modeled it up with a combustion chamber that resembles a Winfield crow foot chamber. I test cut a...

Recently, someone advanced an idea to me for moving heads in more quantity and with reduced pricing due to bulk sales. I am just starting to investigate and have posted the idea on Facebook, including the MAFCA page. The idea is to offer a dealer-type discount to Model A clubs where if a club...

There may be no interest in this here but, just in case, here is a picture of the latest 5 main aluminum block casting with the sand off the outside only. The casting looked flawless from what I could see. I am making several of these and iron also for waiting customers. Also going to be...

I was talking with someone who mentioned a few Model T speed parts and a couple that came up were a Model T Winfield head, and a Rajo OHV head. There was also a magneto drive front cover, and some kind of expensive and rare engine block, but the Winfield head was the focus of the discussion for...

I finally have some time to get back on finishing the tooling design for my 8BA block. Things have been absurdly hectic the past 2 years and it looks like I may be getting a handle on it all. A couple of days ago I started back on tooling design so I can get a casting made. The delay was...

Up until recent customers inquired about an iron 5 main block for use with their 5 main cranks, I have confined myself to aluminum 5 main blocks and regular 3 main blocks. But, since opportunity for quite a few 5 main iron blocks has presented itself, I went ahead last week and took...

Despite the virus delays we are making more heads, blocks, headers, etc... Here is just one skid of Thomas and Winfield iron heads shaken out today. More stuff to be poured soon. Tod

After having to wait a few weeks since getting a dozen Winfield head castings in, I was finally able to get to machining them this past weekend. I think they are machining up very well. Several from the last batch are in the hands of buyers and will be on the road soon. Tod

...make their way to usefulness. These pics are from a customer that is about ready to install it. I have one left from the first run of castings. Tod

Here is the first iron OHV casting. Still needs cleaned up and final shot blasting. I think it came out very nice for the fist one. Tod

I had to do some work on the 2nd OP side of the fixture to accommodate the Winfield heads since I have not machined any in this fixture before the two I am machining today. Here is the first one all machined. The chambers CC at 120cc's including the 4" diameter piston relief that is .045...

OK, here we go with the first aluminum 5 main block just out of the sand. After talking to the foundry, it sounds like I need to provide for chilling a few spots, but for the first attempt in a new molding and pouring method, I think it looks pretty good. Can only get better from here on. Tod

I had a great run to my iron foundry this afternoon to take pictures of yesterday's pour of iron castings. 5 B heads, 2 Winfield heads, and 1 block were among things they poured. Things looked great as far as can be seen prior to heading to the cleaning room and shot blast. Tomorrow we pour...

I just picked this up today at my new foundry. It looks better in person than in the pictures. I have about a half dozen to make right off the bat. Probably going to be $600 the first run. Tod
