Looking at the guide got me thinking, a 75 or so wagon came with both and was wondering if there are any opinions from those who are familiar with them, what would be the better choice?
351w
Lighter overall, good pistons and rods available but terrible heads and intake. 1.78 / 1.46 valves and .419 lift

351m is heavier with massive long rods with no replacement rods or pistons. But, 2.05/1.65 valves with better flowing heads and intake. .409 lift

Both run the same 1.21 carb.

Not sure if the heads will overcome the extra weight.

Thought?
