Hi Folks,
68 200 block build planning. I'm aiming for 10:1 compression ratio. Before I make any plans on decking the block, I'm looking into pistons. I have the aluminum head, and do NOT plan to turbo, supercharge, or run nitrous. This will be a cruiser, street driven car only, no racing.
Has anyone used Keith Black Hypereutectic Australian pistons? They can be found under part numbers 3327H (flat top) and 3328H (dished). They are sold by Summit for $150 per set. I was curious, as I don't need (or can afford) forged pistons, but I like the idea of a little more serious of a piston in case I want to stomp on pedal from time to time. At the same price as typical cast pistons, are these a good option?

From my research, they do have a higher compression height of 1.530" vs the stock cast pistons at 1.500", but that's the only difference I can tell, aside from a pin offset of .060" (does that matter??). From the KB catalog:
With a difference in compression height, would it be advised to not deck the block based on the current cast piston? I'm planning to re-use my conrods. I don't have the budget to make the bottom end turbo/boost worthy when that's not in the gameplan at all.
Also note the rings, these aren't standard sizes, so any advise on rings?
OR
Am I over-complicating this completely, and I'll be find with just using cast pistons? I figured I could save myself a few bucks in machine work if I didn't need to deck the block, but if I'm going to end up with a headache for other issues, it just might not be worth it.
