Thank you, Jim, I have nothing against zero decking but I also don't believe it is necessary in all cases.

Can you please tell me exactly which pistons were used in your build? I believe you posted it once but I do not recall.

The stock-build '68 has the L2262F forgings. I don't have the compression height on them, but until I am home to measure the stock pistons I don't have anything to compare with anyhow.

I would not object to blending my fuel if I got 100% of the power that the engine should deliver. Running straight 110 to get average performance is not acceptable. I could do better/drive harder with the '76 block/6X-4 I have in another '68, running on 89 octane.

I recently had an opportunity to drive a well built '68 that has me longing for more power. I'd use a stronger verb, but this is a family site after all.
