A neat set of breather tubes added to the rocker boxes that came with one of the 1957 Delta Dual-Carb cylinder heads.
Here is a 650cc Power Max piston that I used to test combustion chamber fitment.
You can see the taper on the outside of the combustion chamber where there originally was the flange relief for the 500 cylinders. The powermax piston fits inside, but a clay test needs to be done with the engine assembled to see what's really going on. The piston does look to match around the outside, possibly giving a good squish band?
Imagine this head on top of a 650 sleeved, close pitch fin, alloy cylinder as described in the previous post. That would be WILD!
I am in need of a matched pair of 1-1/4" AMAL GP, stub mount carbs if anyone has some for sale or trade.

Winner Ed Kretz Jr. on what appears to be a box stock T100RS. If you have any info or parts for one of these rare machines contact Wes at Four Aces Cycle as he has one that he is collecting parts for.

I just recently aquired this kit complete with hardware and these neat formica insulating spacer blocks that include a balance tube provision. The original kits as offered in 1957 did not have this type of block with the balance fittings and I'm not sure when this feature was added. Not very pretty, but I was thinking about making some type of fabbed and chromed hard line for a cleaner, custom look.
The new manifold sold by ebay seller zanewillcameille . He makes some neat parts that are designed to work and look good. He's also a life long Triumph guy that drag raced back in the day and currently has a land speed pre-unit that he completely built from the ground up. His 650 manifold is cut to take ground down allen mounting bolts allowing for a larger intake bore diameter of 1-3/16".
With his alloy spacer blocks you could port it out to 1-1/4" or bigger. A really nice looking set up and if you can't deal with the billet look (I know, I'm f*cked in the head that way too) a lite sanding and repolishing to take off edges and machine marks should have these looking just right on the polished TR6 cylinder head.
The real thing
New for 1957, the Splayed Port two carburetor cylinder head that became standard on the Bonnevile in 1959. The Triumph T100RS was the only 1957 model equipped with this head but it was available as an option for other 500 models.
Not yet available for 650cc engines.

The 1959 Splayed Port Head with dual Amal's was just added recently. The polished alloy head really accentuates the finned timing cover, and the polished MCM caps that came from my stash through trade are the cherry on top.
