Hello
My engine is almost stock, only bigger valves and a bigger carburator.
Yeah it's my car upside down, during the rebuilding.
now it's on his wheels:

sweet.
I do love the color. My daughter has selected a jade/teal type color. I don't care for it much and its pricey.

So with the big valves im guessing 45HP?
My 600 is an early unit with suicide doors but it displaces 750cc.
The motor is complete but im not touching it untill the body work is done.

Iv'e been thinking of placing an 850 drive train into the car, Any thoughts?
