Breaking in the engine is easy don't worry about it. If we do go N/A, we're going to want to add a little more compression. I think Joe said that the engine had around 9:1 which is on the low side for N/A. I think something around 12:1 would be right and we should run it on 100 octane. We will have to have the rotating assembly rebalanced if we change the pistons. I only paid $150 when I did the forged pistons in the Cobra.

$150 for the balancing or $150 for the pistons? It's not a big deal, just working out pricing for cost benefit for maximum ROI. The place where I bought the heads has their own fully balanced, fully forged stroker kits for about $1,400. This is the absolute outer limits of what I'd even consider, but if a set of pistons and balancing run up past $500, I'd at least think about it.
If we go hi-comp NA, I'd like to go E85. It costs nearly half what 100 octane does, has about 105 octane, and has other nice attributes. Quickfuel has conversion kits for 4150 Holley carbs. I *think* E85 means we could go even a little higher than 12:1. A big cammed, high reving 13.x:1 302 in a 2,500lbs car should move. :smack:
