That is the balancer. Small compared to newer engines. http://www.damperdoctor.com/Merchant2/merchant.mvc?Screen=CTGY <http://www.damperdoctor.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=D D&Category_Code=CHE> &Store_Code=DD&Category_Code=CHE
Check this site for a run down. I just looked at ebay there were several listed with photos. I have modified several 283 in the past. To do as much as you have indicated a cam swap is just a step away. I also suggest looking for a set of reconditioned 305 heads. They are cheap but let you run unleaded gas. More HP and better mileage.

Jim, Thanks for the post. The thing is, with the 283-2 barrel engines, there was no balancer. It just has a hub to provide a place to bolt the pulleys to. (The 4 barrel 283s, 327s, and the sixes all had actual balancers.) Hard to imagine this seemed like a good idea to Chevrolet engineers; the accountants probably liked it though. Not sure what years or models had this setup. btw: This engine only has 35,000 miles on it.(99% sure that's for real) I'm just planning on cleaning it up, replace the valve seals, and do the usual tune-up items. Since the exhaust is rusty, its the right time to do the duals. Then might as well put the 4 barrel on it too. Pete
