434 smallblock q\'s Im really thinking about a 434 smallblock for my street truck. I found a decent price on a crank and rods. But im having a hard time with pistons. Im looking for around a 9.5-10:1 compression ratio but the lowest i can find pistons for is 10.7. This engine needs to run on 92 octane, and even with a good cam, id say that is too high to make it possible. Anyone know any good piston sources?
