NOT JUST A NUMBERS GAME


Shortly after graduating high school I got a great job working for Lamar Walden down in Georgia. It was a great experience for me right out of high school.  Early on I did not get to do any cool machine work like a 3 angle valve job or  any block boring.  What did get tasked to do was organize a huge collection of old motors that were sitting out in the back lot. There were hundreds of them including small blocks and big blocks. I saw it all. My job was to tear them down, identify what they were, do a pre-inspection for damage, then put the blocks in the vat for cleaning. I quickly learned what to spot. I learned what a set of 292 heads looked like verses a set of  boat anchors 305s.  I could tell what had a steal or cast crank looked like.  I could get in the ballpark of basically any Chevy motor out there was before pulling it apart. I learned to spot the harmonic balancer from a distance to see if it was worth further investigation. I learned to tell if it was a 4 bolt main without taking the oil pan off. It became a game. A game that has been with me for many years.

Today I decided to write a little article and throw down a challenge. Here it is:

The Challenge - “A NUMBERS GAME” We are looking to create a nice  photo collection of high performance parts for our patrons. If you have a digital camera and you come across a old  early model high performance head , snap a photo and send it to us. If you can only snap a photo the identifying mark that would be great, but for you can get the casting number as well that would be superb.  (We would love to see the # number ID casting mark uder the valve cover if it is possible)
 


By the way, I know I have only spoken about Chevy’s, but this site is about all hot rods. If you have any knowledge about a Ford, or a Dodge, or any hot rod out there please send us the details.

Finally, looking in another direction this marks on the sides of the heads are in a certain sense artwork themselves. They are similar to a LOGO. They identify the type of head through a visual representation. So for all you designers out there, the next time you’re at a show look around for other things that could be considered a logo on a car besides the traditional things we think about as the art.

I had a '58 corvette with the original "old style" fuel injection. I remember the double hump fuelie heads and the peculiarities of the F.I. The air meter was always needing adjustment, and the engine would be hard to crank or not at all if there was a drop in barometric pressure. I found out later that was due to the rubber diaphragm in the fuel meter that was sensitive to pressure and would either limit or cut off fuel!. I later traded the original F.I. for a '63 model one with the removable plenum top and a much improved fuel sensitive fuel meter. It was very responsive, and I can still remember the distinctive "whistle " it would make if I ran it withe air filter disconnected. These systems were way ahead of their time. If only I had them back! The combination of the Duntov cam, good flowing double hump heads, and the fuel injection will always bring good memories!
