You will have to get around the fact your CIS piston domes have a big lump on them in the wrong place. This prevents you from using the early camshaft profiles.

With RS style pistons, this motor will rock, believe me! You could look around for some J E pistons or some CE/Aris pistons. Mahle has some 9.5 cr pistons. These would be ideal for this motor with a set of carbs and some early "S" or Solex profile cams.

Probably somewhere around 210-220 hp! You could live with that.

Good luck,
