Having the same issue with a freshly rebuilt sbc 400. 500 miles and just started smoking and plugs are all black immediately. using oil but not a lot. Ran great no smoke first 300 miles.
Whats the quench like? I guess thatll cause poor ignition and carbon things up too. Kind looks like it has poor quench as well given theres no clean spots anywhere in the chambers or pistons. That piston clearance is wild though.
Can’t wait for a part 2!
Good content my guy

Breaking in the rings is very important for the first 500 miles. And I prefer sae 30 oil non synthetic
