383 = 400 crank and a .030 overbore, just so we aren't confused. Eric gets it.
Whats wrong with your currently? Just bad compression or did you throw a rod through the block or something? Need more info on whats going on.
well, lets see, engine is ticking real bad when cold, guessing either lifters or piston slap, seafoam did nothing, rislone helped for a while but its pretty bad again.
coolant dissapearing with no external leaks visible, although i dont think its going into my oil, might be leaking into the engine and then getting burned, not sure. so i dont know if its the intake gasket or head gasket.
it has 216k miles on it, did a compression check on 3 cylinders and the pressure ranged from 125 to 175 on just those three, pretty wide of a range.
