By putting the 3k head onto the 4k bottom end,does that raise the comp ratio?
If so could i put a 4k head onto my 3k block to lower it.
The reason i want to do this is im doing a carby turbo setup and I dont think that the std comp ratio will suit the turbo setup.
Has anyone done this,what comp ratio did u get?
thanks.
