Here is a low tech engine, my Easthope Marine, 3 cyl 30/40 hp. 40 hp at 720 rpm. Built in Vancouver in 1947. Bob
This may not be right for here. But I will give it a shot. https://www.youtube.com/ embed/AsKjPwRaA5Q
Rich..that Morton & Brett Dodge conversion.....any more info?..is it a recent conversion.I say that only because of the style of rocker cover but either way it looks interesting.........and the Stevens conversion is especially nice......there are a few pics of it in various early 50's books I have.......with all the late pieces on the engine I'm assuming that it ran recently........how did it go?..........thanks for the pics BTW.............Andy Douglas
That is a Vertex magneto running through a right-angle gearbox, with provisions for a mechanical tach drive and mechanical rev limiter. In a stock 300 Ford the intake is on the right (passenger) side of the engine. But when I moved the intake over to the left (driver) side it crashed into the distributor. So I made this right angle gearbox using two Boston bevel gears (# HLK 101Y) to lay the magneto down. I painted a spiral on the mag shaft so it was readily visible when running.
You have no idea how much time I had in the M&B rocker box. And it was still junk. Lots of JB Weld by the time that picture was taken. The head is original from the early 30s. The Stevens OHV ran good, 173.253 on gas in a odd looking Comp Coup at El Mirage as I remember.. A few M&B pics.
Rich.......you'll have to excuse my ignorance but is that M&B head made up of two pieces?........I'm trying to work out exactly whats what comparing your original engine pic that shows it painted yellow and the pic showing it in the original cast iron.............you have me intrigued............lol...........can you explain the port arrangement as I can't work out if its an F head or normal OHV intake & exhaust...........lol...........could you shed more light on the subject, please...........lol.....thanks, andyd
The above picture is the head exhaust side on a 26 Dodge Bros block. Pre "Fast Four" Note the block has only 4 exhaust ports. No longer used after conversion to OHV. Single intake on the other side. As you can see from the combustion chamber photo, it is not an F head. The picture in the car, painted yellow, is the intake side, Here is another picture of the head on the bench when I was working out rocker arms for it. Three exhaust ports two intakes on the other side.
Intake side. Note the single intake port or the original flathead Dodge configuration. Also all the brazing I did to repair the freeze crack in the block. Four holes below the OHV intake ports are for spark plugs.
Whitehead engine circa 1900 One off hand built for the Stutz Black Hawk LSR used at Daytona Shores by Frank Lockhart, later used at Indy
Arrow Aircraft OHV Ford Flathead Conversion, It featured individual port fuel injection and a Harmon&Collins magneto.
Tornado OHV Ford Flathead Conversion. It featured custom seperate intake manifolds, The heads could be ordered in compression ratios from 7:1 up to 16:1. In 1950 one of these engines ran 175mph at Bonneville in a streamliner.
More on the Fronty-Fords, and the author snuck in some details on other engines too. Part One did not document any engines.
How about the George Riley SOHC V8 Ford? Ford Engineering refined Riley's design and built a few of their own in like fashion that were run on the dyno and even tested in cars. It was rumored that a few found their way to Argentina and were run in race cars. On a side note, it bothers me when people spell the name of Kenny Harman wrong like the author did here. Harman was a gifted mechanic, machinist and cam grinder.
Fordors............thanks for the info & pics.........Strange that the Frontenac article doesn't mention the Frontenac DOHC Stagger Valve arrangement................have seen a couple of pics of them over the years and they would get my vote as the ultimate T engine conversion.............tho' to be honest any OHV/C conversion would keep me quite for a while.......thanks.......andyd
