AJ's Opinion; what size SBM do I need

Tall deck 383 or low deck 383 if we're going to mix the two of them their performance option....and relating to them as the 318 of Big Blocks then we can compare the poly 318 to the tall deck with its two 4 barrels and then the LA 318 for a single four-barrel like the ld 383. That's how I see it.
