I would enjoy any related discussions. The engine I am most familiar with is the 383/440
series although I am currently working on a 380cu in "A" engine built with readily available
parts. So far it looks good. I am familiar with early hemis as well as the 426 series, slant
sixes both hot street and race, 426 Max Wedge, Hoover style 360 and normal and hot
versions of the 340.

Believers are always welcome.
My machine shop is antique but functional with a Van Norman 944s  boring bar,
a Sunnen hand operated rigid hone, an early Sunnen rod hone, a Tobin Arp cap cutter,
a Soiux 345 valve shop, a Peterson spring balancer, a Smithy lathe mill drill, a Van Norman
564 surface grinder,a home built flow bench and some home brew balancing fixtures.
We are trying to make an engine dyno but so far it's just a big engine run-in stand.
I also write an opinion column for the Prince Edward Freepress. It is published weekly and
can be found online at www.freepress-online.com. Look under Features and it is often listed
with just my name. The column is called the View From the Ridge and is based on local
memories and events or childhood experiences. The papers editor Glen Tooze has given
me a free hand and so far it has been fun. Their website is maintained to the best of their available time however as I sure you can understand the production of the paper must take priority.

SHOP TOUR
Below you will find some of the things in our shop. I will add more as I get time and photos. We do most of our machining in house. Our flow bench is a homebrew job that has been a big help. The design came from an article in Super Stock magazine done by Victory Racing. It works well.
Pic one is a piston receiving a flycut in it's valve reliefs on our Smithy lathe mill drill.It is probably one of the best pieces of equipment for dollar value we have bought. While not the highest tech piece for sure it is very versitile and there is little that can't be done on it. The boring bar is a 944s Van Norman which was a very popular bar. The valve machine is a Souix 645 and is complete with seat grinding set up as well. The surface grinder is a 564 Van Norman. It is a huge machine and does an excellant job on blocks heads as well as aluminum. It will handle even the larger diesel heads. Stone wear with the general purpose stone is almost imperceptible. A generous supply of coolant keeps everything cool.
                  
                     What you can't make on a Smithy Lathe Mill Drill isn't worth making.
 
                     
This is our Souix valve grinding machine. It is a particularily good one and does an excellant job.
 

                   
Head work is tedious painstaking work but that's where all the ponies(HP) are hiding. We use various methods depending on the particular situation. Here we are knurling guides which are slightly worn. Knurling is a good repair but it has to be done properly. It is a three step operation when done right but most people try to do it with two which is completely useless and gives knurling a bad rap. Guide replacement is the best repair for anything but minor wear although a properly knurled guide can be a high quality job but it requires extreme care.
                  
Here is a Mopar Stage 6 head being tested on our homebuilt flow bench. A flow bench is a valuable tool but it won't lie to you. You quickly discover what not to do more so than what to do. Actually we were able to get these heads quite high in flow but it took an awful lot of work.
 

Here is a Stage 6 head undergoing a precision 3 angle valve job.The position and width of the actual  seat face is a critical part of power production. 
 
Here is a 36 Dodge truck block getting it's deck resurfaced on our big Van Norman Surface Grinder
