Budget 318 build

NM- AJ
what about the lighter and higher compression Ht Magnum pistons? (if he needs pistons)
He has one of the better short blocks already short of a later roller cam motor
let's hope he does not have the dished truck pistons
The best stock-ish pistons I have ever found are the 526's (early rings) and 814's (later rings)... flat, no eyebrows, and about .075 below deck. I am not aware of anything different with the Magnum 'cept the deck is about .015" lower. There are indeed lower CH truck pistons out there.... not sure WHICH trucks they were in but the CH is another .083 inches lower...yikes.... over .150 in the hole! Beyond that, then you have the KB's, Icons, and so on.

But as said.. the OP is on a mission to do the minimum on the 318 and be safe and just get this running. His 360 is where things can be different... if he so chooses. All he can do is advance the cam as suggested.
