440 budget build

Well I'm new to this cam choice option so what suggestions would it be? This is a lower compression motor an just for street use.

Look at the comp cams xe-268h and the comp cams xe-274h ..

Look at some of IQ52's threads here on FBBO. He's made some serious horsepower with low compression 440's. Common wisdom is go with a cam that conserves cylinder pressure with a mild duration and overlap. It's really interesting because IQ52 totally bucks that. He's made crazy horsepower with the comp extreme energy 285 cam on these low compression motors.

The 346 is not a bad head as open-chambered heads go. I would focus more on the goes-into's. What kind of intake and carb are on the engine? Also, are you using headers or stock manifolds?

You can make alot of power with low compression engines, it just does it at high RPM, and the low end torque is somewhat ignored by using high stall torque converter and more gearing. This is fine if you have a drag race car or weekend hot rod, but is not a good option for a true street car.
The cam I mentioned was just a guess, we really need to know the vehicles application, true compression ratio, converter stall speed, gear ratio, tire size, and intake/exhaust system. Also fuel being used and altitude driven at.
The camshaft you select will affect the "shape" of the torque curve, and you want the torque curve to match the rest of the car combination and the application or how the car is being used.
For a "street" car you may have better results with a smaller cam that makes 450 ft/lb of torque, but only 350 HP, than a cam that makes 450 HP, but only 350 ft/lb of torque?

First thing to do is get rid of that stock intake. They are worthless. Look for a good deal on a used dual-plane Performer or similar aluminum intake. Best $100 you'll ever spend.
