British Anzani A & B Stock & Alky Racing Engines
This engine post is going to be one large one when done. (some 30 pages) I wish to thank Smitty-The-Welder, the late and great Bill Tenney (Mid-West) and Gene Strain (Calgary, AB Racing Assn.) for all the materials concerning these engines that will date all the way back to 1959. By 1965 these engines as Alkys (Todays Pro Class engines) were already going in excess of 80 miles per hour and by 1981 were going in excess of 100 miles per hour, setting records where some runs were going up to 107 miles per hour hitting raceboat, prop and other technological barriers in the process.
The first feature will be some introductory materials to the British Anzani racing outboards that will shortly be followed by the complete type written 1959 manual produced by Bill Tenney himself in 1959 for racers purchasing his engines and modifying them for Alky themselves if that is what they wanted to do. Enjoy one of the first "cast iron" blocked loop charged engines that was part of that technological revolution that also produced the Quincy Flathead Loop, The Harrison Loop, The Konig Loop and other hybrid racing engines producing amazing horsepower before there was really the props and raceboats to handle that kind of output.
Enjoy the start to this thread, the entire 1959 Bill Tenney British Anzani manual will follow this opener in a short few days. :)
In the meantime if there are some posts of pictures and stories you may want to add into this thread, please do. Everyone will be pleased to share your pictures and your experiences.

BILL TENNEY'S (Aeromarine Co.) SPECIAL INSTRUCTIONS FOR BRITISH ANZANI MOTORS 1959
Putting this together for BRF readers and writers was no mean feat. Mark 75H mentioned that I had to get larger but then 50kb size is the limit. To do this with generation re-copied status was quite trying. Thanks to the late and great Gene Strain (Calgary, AB. division of the Alberta Racing Powerboat Assn. of the day) made this possible. Not only did he sell me his well run B - Alky Anzani way back in the early 1980s, it came with this 1959 Bill Tenney's Special Instructions For British Anzani Motors too. When I got them they were terribly faded so there have been so many enhancements done to bring them to their resent hard copy state, I suffer from severe eyestrain! :)
In any case keeping in mind that there is a 50kb limit to each posted Jpeg, remember they are downloadable from this site and you too can enhance them some more to make them even more readable or get some steno with good googly eyes an old typewriter to redo them fresh save for the wavy lines that are so original.
Enjoy the late and great Bill Tenney's works now following this narrative. :)

Bill Tenney's Last Page Of British Anzani Instructions 1959
BILL TENNEY'S LAST PAGE OF SPECIAL BRITISH ANZANI INSTRUCTIONS 1959.
:) With any luck and gone really cross eyed with enhancements AGAIN! In about a week or less, there will be featured the British instructions typed on British Anzani office paper on the engines plus a parts and price list from way back then, scanned, ENHANCED and poster here on BRF. Please don't ask me what those British money figures mean when you see them! I know nothing! Since then even they have changed!
Thanks Sam - I will do some more for future posts.
It is something else when it comes to black and white scanning. I will give your suggestions a go that way and see what will do the trick. The Anzani maual was a virtual bleach job from the age it was done, printed and copied and I am getting better at desktop publishing, some much can be done these days than even a couple years ago. Thanks Sam. :)

Some British Anzani Parts Both Stock Racing And Alky
The following series of posts are a large attempt to identify these engines by powerheads and major components through out the engine. You can see there is some of Bill Tenney's written manual in some of the parts seen here from both A and B Stock and Alky racing in single carb format but in a variety of barrel sizes for the class applied too. Just think? You may have some of these parts getting dusty under your work bench and this can help to identify quite a few components for the readers and writers to this board. If you have some pictures and stories of your own for this section, please add them.
In the meantime, enjoy these picture batches of British Anzani engines and their components. :)

The Mikuni Carb picture - done in error - sorry! That is the Future
The Mikuni Carb does not belong in the Anzani's history. Done and submitted in orror. Please disregard the Mikuni pics. Sorry.
Batch 8
More British Anzani Parts Components Pictures Coming
There will be some more picture batches of Anzani components posted shortly to add to all the previous pages to round out everything possible. :)

MORE ANZANI INTERNALS & EXTERNALS PARTS
ANYTHING I MISSED I will add sometime sooner than later
I know there are things I missed like 2 carb crankcase, other carbs and other things here and there that would still need unwrapping and storage de-greasing (what looks rusty isn't, it the dirty grease and farbric coverings mess left behind prior to cleaning). At some point I might add things that come up from time to time as they happen in the future.

British Anzani - B - Stock - Brand New From The Wood Box
This British Anzani B- Stock gasoline racer may be the only one if the world left that has never been started. I hope it it never will be! for its value is just that.........never been started.

ANZANI WITH STINGER PIPES & ANOTHER WITH DELORTO FUEL BOWLS
These two pictures are from another part of this website and are an excellent representation of what was going on withe these engines. Pictures courtesy of this BRF site (Jeff Lytle and the late Ron Collins (I understand)). They show the DelOrto fuel bowls raised high above the flywheel is the exact way Bill Tenney spec'd his engines. His did not use the remote fuel pumps and return spill over systems back to the fuel tank like the later Hallum and Anderson versions seen out West. They came mostly one or two bowled required to still use the single float gravity needle and seat float system in the Vacturi carbs. Why one or two and sometimes three DelOrto remote bowls?? They were simply to give the engine the fuel it needed gravity fed without overflowing and they ate it, methanol and more than 20% nitro fuel drinks voraciously as an A or B versions with the like wise number of DeOrtos feeding them gravity fuel.
I heard some time ago that stinger pipes were being tested by the late and great Bill Tenney as well as the movers and shakers out west too but when you compare todays computerized formulas that bag off a set of pipes specs and manufacturing specs off your PC or laptop, these people were already thinking far in advance of where this was all going. The amazing part was that they were hitting the century mark of 100 mph by the 1980s without stinger pipes/expansion chambers. What would computer designed chambers do for their design now? They had some CD ignitions by the 1980s but had not strayed into the flat slide or round slide carbs at that point yet the original carb for these engines was a round slide carb called an Amal Monoblock that you find a whole host of on British motorcycles. Obviously the technology to take slide carbs to the next level using methanol and nitro mixes was far behind volumetric and butterfly throttle opening technologies. :)

Both Pictures Are Already On This Site To Download
Both of these engines, the one with the DelOrto bowls held high and the one with the stinger expansion chambers are already on this site, under "coolest racing egnines of our time", So I copied them to this section to honor their contributors with the alignment of those pictures on this thread too to give readers the most perspective possible of their evolutions as part of the British Anzani thread. I hope nobody minded?? They fit real well as does this 4 carb version that came through Charlie Williams of CORE website. :)
I have some older pictures of the DelOrto high mounted bowls somewhere in storage here until all the renovations are complete to get them and post those as well. I had a picture book full of these beasts running against Quincy Flatheads, Harrisons and Konigs at races here when I was a teenager, pitman and DSH driver, but, a friend of mine in a marital splitup lost the whole thing negatives and all were sleved in with it. That is one loss to me and would have been great for this site too.

ROGER WENDT's - HYBRID ANZANI 2 CARB "B" - ALKY
Prior to 1980 Roger Wendt campaigned this true hybrid Anzani based Hallum - Anderson version in Flathead Lake and North West Alky competitions. Though it was a 2 carb with one small carb over the rotary valve (Tillotson HL) and one real big one (Vacturi) it was simple in terms of overall form and remarkably fast and reliable with running 40% nitro in the methanol fuel mix.
*Described fully it was: Anzani cast iron loop block, crankcase & pistons.
*Next generation crankshaft and rods where the earlier used bronze bushings in the small end of the rod, this was had caged needle rollers. The big end crank pins where straight instead of tapered into the top and bottom crank components to crank component alignment.
*Phelon flywheel ignition.
*Harrison rope plate.
*Mercury clamps and saddle.
*Konig gearcase.
*Fabricated pipe tower housing.
*OMC high volume fuel pump for return to tank fuel system.
*Well proven bell exhaust system.
*Mercury steering adapter and steering bar system.

Anzani - Typical Modified To Twin Carb Crankcase
This crankcase I understand is typical of the Anzani Alkys developed in the North West by/for Hallum, Anderson, Sutter and for people like Roger Wendt and The Strains (Gene & Bill) where 2 carbs were applied. The Primary Carb, A Vacturi not seen here sits on the cast iron block's piston ports and where there is a torturous S passage from a block port to the crankcase cranshaft rotary tunnel, the block rotary valve passage was left to work too and also a Tillotson HL (quite small for velocity reasons) self pumping carb was positioned on the Crankcase outer wall directly across from the crankshaft rotary valve opening area as well. This created multiple major streams of air fuel, one original via the big Vacturi carb and the others bent from the vacturi through that tunnel and from the HL carb direct on, to the crankshaft rotary valves making for such air/fuel feeding that included the piston ports with modified piston skirts too, there was virtually no part of the engines single revolution where some port was opening and some closing with all the overlaps that the pulsations at the intake normally associated with piston port and then also piston port and rotary valve combo engines became near steady streams of high velocity air/fuel that really power packed the engines to do the speeds they did. These engines were breathing and more was to come!
