Guys & Girls, I need some suggestions on my 1973 z28 T code 350. It is mostly stock, I have headers and HEI, that’s about it. Stock qudrajet, head’s and motor. The heads have been redone about 9 years ago (Stock set-up, lifters, valves & springs) original bottom end. This is a numbers matching Engine, I don’t want to ruin it BUT! I want a little more horse power. Any suggestions. Besides cam and aluminum heads? I’ve been thinking about pulling the T code and throwing in a BluePrint 383, just so I don’t ruin the stock 350. What would you guys and girls do?
