so i was thinking about your project today and really all you need to do is make an adapter plate then put the piston and cylinder on figure out where it needs to be to have the proper squish and take it out of the bottom of the cylinder you will more then likely have to ramp the piston and change some of the port angles and stuff or both to make it work out but thats ok ;) make the adapter plate out of steal as thin as you think you can go to still hold the threads...

Don鈥檛 you Think it would be better too make the plate out of aluminium? And the adapter plate is most used for matching the ports to get a good flow, because I would rather not begin welding the cases.

I can always make treads in the block to match the cylinder bolt pattern.

but now when I think about it. It would be nice to have threads in the adapterplate so the block is more 鈥渟tock鈥

I wouldn't thin down the block they are already to thin and the cylinder bolts are already known to strip plus the pig aluminum that it is made out of will just pop.

Yes, so the adapterplate then would need to be at least 2-3mm thick to get a good flow from the small ports from the block to the big ports on cylinder. So I don鈥檛 need to trim the block that much.

Right but your going to need to trim down the cylinder in a lathe or on a mill to get the port timing right no matter what...

You won't know how much until you get the cylinder that you are going to use and the Piston mock it up with a degree wheel

Yes, i am going to ask some questions on the Way, because this is a big project for me and a lot of new challenges.
Thank you for all your feedback.
