Re: need a adjustable cam sprocket for 1978 1.6
Big end width is the same. Turn the crank pin down 0.037" and get some $800 Ross pistons with a 0.990" compression height and figure out the dish or dome cc you need for desired compression . Balance the crank add main studs and viola. Awesome bottom end with a 1.79:1 rod ratio good for 350hp at 8k rpm.
