Hello, i am in need of some advice in choosing a cam for my 400 thats going in my 1975 4x4 trailduster. Its a 30 over 400 with KB 240 flattops,ported and polished 915 heads with dual springs good to 600 lift,compression ratio is right around 10:1. edelebrock performer rpm intake with holley 770 truck avenger carb, hedman 1 3/4 headers, 4 speed manual transmission, 3:55 gears and 31 inch tires. I can't seem to find any similar builds around on the internet. Any advise appreciated!!!

a 4x4 needs a TORQUE engine. if you put a HORSEPOWER cam in it you will never be happy. contact a couple of the cam companys and get their recomendations for your best results...
