Yes. They are 916 cylinders. I also have a complete set of 748 Fast by Ferracci race camshafts as well for anyone interested.
I will do combo deal with these pistons/cylinders and the FBF race cams for $1200 shipped. http://forums.13x.com/index.php?thr...afts-748-888-916-996-998.354507/#post-5373058
