I think it is an OS Max 3.5 but not sure.

The carb and exhaust cooler is aftermarket.

If anyone has this block I would like to know the neck size of the carb and exhaust hole spacing and opening size, or know where else to look.

I am hoping the carb and the header will fit an OPS 3.5 SE which I have dimensions for.
