Great pistons for my Chevy Big Block rebuild. They fit perfectly and the quality feels top-notch. Definitely noticed smoother running and better throttle response.

The forged quality and finish on these pistons is excellent. Installation was smooth, and the forced pin oiling gives me peace of mind on longevity. Highly recommend for moderate builds.
