Best Block

Get a Mexican Block

They are supposed to have a higher nickel content and beefier web supports. My dad's 73 ranchero has a mexican block. My 70 Torino and 77 Granada did not. I think they are mostly in early 70's vehicles (probably more likely in trucks). You have to remove the intake manifold and find the "hecho en Mexico" casting in the middle of the lifter valley. Before they had aftermarket blocks, the mexican blocks where the ones that people stroked.
