I had a 318 in my 69, added 360 heads (Milled .100 down to try to get some compression) holley 4 barrell, dual exhaust and a mild Comp cam. Worked all right but not spectacular. Should have run a higher stall converter for the cam.
Then I had a 360 built with a 4" stroker crank, roller cam and a bunch of other stuff - This is a fun motor - idles at 650 RPM, lots of vaccum, (Power Brakes), and the best part is the torque. over 400 ft.lbs from 2500 RPM and over 518 ft.lbs peak. IMHO there is no replacment for displacement. The most fun I have ever had driving a car.
