What size can a 5.2 be bored over? I know alot of older 318`s been bored for 340 pistons but how about magnums? I just got a 5.2 thats been sitting and its got rust in the cylinders so an overbore is a must...
I think I remember seeing about .040 is the max. Anything more than about .030, I would have it sconic checked.What size can a 5.2 be bored over?

I was looking for a 5.9 but those are rare here in finland, pickn pulls were asking 1500€, its almost 1800$Let's not forget you can stroke 'em or even just start with a 5.9 and go from there!!
The 318 from Hennsely gets sonic checked for a 4.00 bore.
The 318’s cylinderwalls are only so thick. How far it goes needs a sonic check to know for sure.
I suggest not think it can go to a 4.04/340 bore.

I was thinking about stroking, but that includes 0.030 overbore also and a 2000$ plus freight plus taxes so ill be in 3000$ then...

That would only be the shortblock.. add heads, cam,valvetrain and intake...3K is pretty cheap for an engine.
.030 , is .005 over an 1/8" -----------------------1/4" is .0250360 bores are a +.090 but 340 bores, thats a +.130, or over a 1/4 in.diameter overbore! If thin is in, they are Flynn! Now 'big inch' is more
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
plausable with > 4.15 stroke LA cranks available now.

.130 , is .005 over an 1/8" -----------------------1/4" is .250
