I run a 78 Alfetta 2.0l in Chumpcar. History of the car prior to 2012 is mostly unknown. P/O started converting it to a race car, I finished it! I've refreshed bearings once and did a complete overhaul once, both times I've reused the rod bolts. So far we have accumulated about 130hrs of time on the race track- 7-10 hrs at a time never exceeding 6500 rpm, mostly seeing around 6000 rpm. I don't think Alfa skimped on hardware.
