I'm thinking about getting a tunnel ram kit for my '56 chevy truck. I keep hearing about driveability issues. Lack of low end torque etc. The truck is running a 350, decent cam, late 60's vette heads and a B&M turbo 350 with a 2500 stall (about),valve body set on "whiplash". 3:73 gears in back. It runs great with the speed demon carb and performer RPM intake but I just like the visual impact the tunnel ram gives. Any thoughts? Thanks.
