Just bought a newly rebuilt LA 318 and asking about this cam that was in it?

Fresh rebuilt? Doesn't look like it....heavy carbon buildup, allready has rotted freeze plugs replaced with temporary rubber job, crusty looking all over......marks on pistons are probably from a timing chain issue previously, is it still std bore?
That's the one thing the guy didn't do is fresh freeze plugs. I mean fresh like it probably had a few 1000 miles on it. The carbon dusting on the valves and top of pistons was very thin. Like really thin. I think the guy either put in regular steel freeze plugs so they rusted really quick or he just neglected it altogether and the motor has sleeves back to a standard bore. Either way we are putting all new plugs, seals, cam and crank bearings back in it for safe measure also hot tanking the block and heads.
