Hi I,m in the process of making a 1500 engine for my (mkiv 75) . All with small money. I started with a dolomite block, i,ve put a mkiii 1300 cam in on canley bearings . i,v put pinto seals on the inlet valves . i,m using a 1300 flywheel with bored out fixings (this saves 1.5 lb on std 1500 ) All bright ideas are welcome . I have fitted a small fan in the inlet , and lastly got an air die grinder to polish stuff .
