Hi KirkMy Tiger's 302 was built with an RV camshaft by the previous owner. The builder was Barry Greenberg, who was popular with the club in the 80's and then had a falling out. I don't have a manufacturer or specs; it pulls strong in the mid range and I'm wasting my time past 5500 rpm's, but it will rev higher. Sorry about the vagueness of the post, but it's at least some seat of the pants info LOL! Kirk
