yeah, what they said. If your going to run a tunnel system on a motor, it would seem more cost effective to have a motor capable of working with the system. With the 350 you have, bolt on a set of heads, an ignition and a good carb. If you still want forced induction, you may want to think supercharging or turbo. With a good intake, you can get the HP you need and still have a Hp look. but a tunnel ram, not a good idea.
