ISO .30 over 360 flat top pistons

But you're still not saying much...just recommending pistons based on a desire for different cam choice is kinda like making investment choices to yield higher returns when you don't know the guy's income. We don't know if you're planning on running a power adder, what heads you're running, what cam...need anyone go on?

That being said, the recommendation before your last reply is a good one. They're close to the deck and should yield plenty of compression. If you want used, check the classifieds, post up a want ad, and/or check ebay for non-stock pistons.
