Rich,

If you remove them and they are still in usable condition, I am interested
in taking them off your hands.  If the owner decides to go with stock
pistons, let me know and we will see if we can work something out.

Cheers,

Rich,
I believe what you have are "turbulator" pistons and are about 1 full
compression ratio compared to stock. I installed a set in a car and knew of
a couple of Healey owners who did the same. I believe they were made by
Jahns.
It was in the mid '70's when I did this.

Hello all,

I just removed the cylinder head from a tricarb 300 engine today and have
discovered pistons I've never seen before. The top of the pistons are flat
but with a raised surface that takes a good portion of the combustion
chamber area. The sides of the raised portion are on about a 45 degree angle
up to a total height of almost 1/4". I can't imagine what the compression
ratio must be, but the P.O. had been working with modifying a set of
manifolds from an
HD6 carb setup, and had modified the inlet manifold to bolt up Webers. So
obviously the P.O. was after some pretty wild mods.
Anybody heard of pistons like this? There are no markings on the crowns
except a small circle about the size of a dime with numbers 1 thru 6
respectively.
I am trying to convince the present owner that we should bring things back
to normal pistons and carefully check out the cam shaft for signs of
modifications that may not be "streetable".
