I have a good friend that swares up and down that he will beat me. He has a 87 monte carlo ss with a 305. He's spending lots of money just to see if he can have a laugh and beat me with a 305. We raced a couple times and it seem like he would need maybe another 75-100 hp. Well he bought a cam, roller rockers, ported and polished his heads(stock), and put a 4:10 gear. I still dont belive he will beat me. What much more can you really do to a 305. He already has full exhaust and a dominator carb. Whats crazy is that motor was only rated at 190 hp.
