Hey,dude..i just wanted to ask if you put the pi heads on your car,i didnt see it on you rmod list,and if you didnt i would suggest you get those cause,the car wont run right without them.and I know its head swap and can be a pain in the ass,but you'll probably pick up a few extra horsepower to,because it will bump up the comression on your older short block,i did the same thing on a customer of mine's car and that was the problem...its worth a shot,man..latter
