Helping a friend with a Vortec crate engine right now. Funny you should say that yours wasn't running the way you like, because he was having the same problem. He's into cars but not super knowledgable. We put this motor in his early 70's Impala. I got him a GM mild perfromance manifold for the Vortec engine, a new HEI distributor for 75.00 off eBay, and a Holley Street Demon carburetor. It runs like a champ now. I was surprised that it didn't have more power, but he told me that it was the most basic GM crate engine available. Anyways, I really liked how easy the throttle cable and kickdown cable hooked up to the the carb.
