Well I've decided to use the Edelbrock 2091 Top End Kit for my 1984 5.0 Mustang. I like the fact that Edelbrock took all the guess work out of the build. They claim that this kit is good for over 350 HP and I've read a lot of good reviews. There were a few negative reviews too. I will also be using the FITech Go Street TBI Fuel Injection Kit they claim is good for up to 400HP. Lastly I will be using 1.6 ratio roller rockers and headers. This should make my little 302 a nice street machine. I don't plan on being the fastest mustang on the block but 350+ HP is way better than the stock 165HP. What do you all think of this combo?.......det45
