Lightweight Crankshaft
Is anyone on this forum running an ultra light weight crankshaft like a Winberg model? If you have one can you share with me what your crankshaft weighs? I have heard they make a 3.75 stroke crank that weighs 33-34 lbs. This seems very light to me but I have heard from some guys that were running ex pro stock truck engines that Winberg makes some smaller small block cranks that weight even less.

look about halfway down the page and you will see some really lightweight cranks...
i am also using a 11 pound flywheel... as far as using it on the street... it all depends on what clutch you use, and how particualr you are about how the car drives. street use to me doesn't necessarily mean bumper to bumper traffic, i would avoid that as much as possible with the lightweight assembly and an aggressive clutch. but i do drive mine on the street, i just avoid high traffic times.

I'm using a Scat "superlight".......about 48 lbs. I thought it was a real nice piece for the money. There's a couple pics of it and other parts of my rotating assembly in my pics to the left

I wouldn't recommend a superlight crank or flywheel for that matter on a street car. Just my .02

I have heard many positive things about Winberg Cranks and I was hoping someone on here could share some experiences with me.
Thanks!
