My 360 Magnum build thread

No magnum block comes with a square deck.
So really it's impossible to make measurements with any accuracy until that sucker is square.

Deck it, and then measure those rod/piston assemblies again to determine whether you'll chuck them or not. I personally wouldnt put any money into them. That's just me though, and only because a set of scat I beams are way better, cheap, and strong.

and not to be alarmist or anything because it's not a build-killer...

Someone take the "cylinder 1" first cylinder shown on the left, and zoom the hell out of it. Looks like there MIGHT be a crack from the bolt hole into the water hole next to it. These are common. I have been told they are not a problem as long as there is no leak. Seems to happen a lot with people using head studs. The studs have a sort of shoulder where the threads end and that IMO shouldnt be threaded in flush up against the block. It might act like a wedge and cause these cracks. I really cant say why they happen with any certainty, or if it also happens on la blocks too, but I see it a lot. They could even happen from not having a square deck to begin with!

Anyone have any ideas?
