Hello

Does anyone know of a dealer/engineer in the West Yorkshire area that will convert a GP200 cylinder and head for a small block casing? Oiltech only convert casings. If anyone fancies the job or knows anyone please let me know.

Cheers

Chris

?

I think you are talking about turning down the spigot, and opening up one of the stud holes ?

It would probably cost you as much as sorting a small block to suit the cylinder.

That sounds like the hard way to do it.

Why not just long stroke a 65mm bore?

a 60mm stroke crank will give you 199cc on a 65mm bore with no case or cylinder mods.

Turning down the spiggot and drilling the stud holes to 13/14 mm allows the 200 cylinder to be fitted onto a small block casing. It's straightforward, if anyone knows who can do it let me know.

The bottom end is already built with the original 1970 crank.

Tried Chiselspeed?

I'll give Chiselspeed a call Monday, cheers.

Had a reply from Chiselspeed, they will convert 200 cylinders to small block.
