I'm looking to buy a crate engine form a local Chevy dealer, the trick is that it's a 85 K5 which stock is a Carb and I'm going to install a fuel injection system. I was looking at the 350 H.O. long block but the guy told me that the engine was set up for a Carb and couldn't be used for the injection. Now what's the big difference if it's a long block? Theres no intake? I thought that I could get any long block and install whatever I wanted. Am I just missing something?? Or was the guy blowing smoke up my a*@.
