Lunati has a sweet cam they recommended for my 273 4speed. I'm running two 450cfm holleys on a old edelbrock tunnel ram. My car is real light though. I look up the cam they recommended if your interested. I get a lot of the same oh it's over carbed but my 4bbl was tuned great while I broke the motor in and with the t-ram it lost very little down low and pulls far stronger mid and upper rpm.
