What is the compression on the hf? What is the highest sohc compression engine I think it's the y8 but I'm not sure. Would it up the compression if I stroked from 1.5 to 1.8? See I am trying to build a good N/A engine that will do some 12's in a rex. Any help is wanted and will be greatly appreciated. Thanx

 

um... use search buddy. (i like your signature)

but i'll give you a start.
the Dseries can he bored out to 77mm with sleeves, which can make it about a 1.7sohc.
