I have a 1985 Pontiac Trans Am...I am going to buying a supercharger in the next couple of months and was looking into a weiand 142 or 144. I will run a completely stock 305 5.0L V8 with it if possible so should i get the 142, 144 or look into something else...? Any thoughts, anyone? (btw, is this going to ruin my motor?....it has 10,000 miles on it and i want to keep it nice)
