Whats a mild cam? MIld to you may be radical to someone else or vice versa. Thats really leaving out a lot of important info by not giving cam specifications and thats the heart and soul of any horsepower making project. Come on now, be more specific with what cam your gonna use.

I like cutthroat. He`s ambious as most young rodders are, but smart enough to ask and listen. As mentioned, give us the complete specs of things and far more can be done to help. Rear gears play a huge role in how a car performs. Since your monte came with a 7.5 rear diff, the 82 to 87 trans am`s and Z28`s came with the same rear. I have the codes of these that tell which are posi traction and what gear ratios they have. Since me and my friends have delt with many mid 80`s Old`s cutlasses which use the same 7.5 rear, we would take the codes to the junk yards and check every single trans am and Z28 there to find the rear we was looking for. When we found it, we would snatch the guts out of it, pay the junker, take`em home and install them in our cutlass. We usually paid $150 for the whole rear only if the junker wouldn`t let us buy the guts. after paying for synthetic lube so the posi rear didn`t clunk and clatter, our total investment was maybe $230. Rodding is all about doing things on the cheap when ever possible. And the 7.5 rear holds up well to 300 horsepower and street tires. If you bolt on slicks it`s a different story. 305 heads are fine to use on a dished piston 350 and a small cam. Many a young rodder has followed this road with good success. The small valves of the 305 heads on a 350 with a small cam and tuned correctly will give it explosive out of the hole power, and this is what makes street cars so much fun. don`t focus your builds on horsepower, focus on torque. Torque is what moves the vehicle, torque is what wins races. If you use a small RV cam with 305 heads, I would use a Quadrajet carb, the small primaries will give it even more low end power, with throttle response so sensitive you`ll swear it`s fuel injected.
