Thats what my intentions were was to take a bit off for less drilling.
The weights simple, lightweight scat I beams and small bore short skirt stroker pistons. Crank should be 2050 from the box and I was using approx weight from a similar build and with the parts I will use im getting 1698 grams. So in reality im looking at shedding 350 grams.
You can shed that weight but it might not be in the right place, I have a crank balancer in my shop and have done many balance jobs. You might get lucky, you might not, probably not, IMO.
How did you come up with a figure of 330 grams. You can cut the counter weights down a little but you need to leave enough weight there to be able to drill where it is needed.
