but if all you are going to use is the block and timing cover and replace the rest of it, is the magnum a better block? i want to build one in the next year or so and would rather start out decent.. i want to keep la oiling since i have the top end already is the main thing..
Well they all have roller camshafts, true 9:1 compression, better rings, better heads, don’t leak water out of the exhaust manifold bolt jackets, seal better on intakes, valve covers. The 5.2 camshaft is a better decent RV grind as well
