Noticed this 046 has a D combustion chamber. All 046 460 like that?

Founds some good info posted by Wiggs in KY on 046 460 cylinders.

((((((((There are several different 046/460 cylinders. The earliest 046's, they had the d-shape chamber, larger transfer ducts and larger upper transfers, coupled with more transfer duration.  The last one i put a wheel on, Going off memory here, was around 100/115/75. Very little blowdown. Stock for stock, they will walk the dog over the late model 460 jugs. Not even a contest....

Then they shrunk the upper transfers and tunnels and gave it more blowdown. Consiquently, the exhaust port got smaller when that happened. Finally they ditched the D-shape chamber, gave it even more blowdown, and a pencil sized exhaust port opening. ))))))

I am working on a MS460 that is for me and not for flipping.   
The piston and rings are toast from scoring but I believe the cylinder is salvageable.

So I have been looking on line and can see there is all kinds of ways to go on this thing.   
I can get a meteor piston with caber rings and use the original cylinder.
I can get any combination of cylinder and piston and rings by names I am not familiar with.
I can also see that there is 54mm I believe cylinder and piston combo by names I am not familiar with.

So what have some of you guys used with success and had run good afterwards.   

If I use the stock cylinder I will open the ports some and shape the upper transfers toward the intake. 
I will also measure the squish and see where it is and see if I can lower it some.

Thanks for any advice guys.

The stock oem pistons are pretty cheap. That would be the route I would go if weather I was keeping it or flippin it. I have heard the meteor p and c are decent.

I was looking at the meteor setup and I may go that route.    I still have to clean up the stock cylinder to use it.    Let us see if there are any other opinions.

Have you looked around for a good used piston and cylinder. Got a couple from chainsawr in the past and had very good luck with them.

Thanks Mike.   I think I will go OEM it seems to have the best performance and of course we know the reliability is good.

Got to find my acid to clean up the cylinder.   I have not used any since I moved and do not know where the heck it is.

May have a usable cylinder here if that one is wasted.
