Thread: bone stock 350 upgrade questions

For a street driver or street/strip driver, a tall, dual-plane intake such as an Edelbrock RPM or Weiand Stealth will add about 10% power (25 to 40 horsepower, depending on your build) over the stocker intake or the low-rise Performer intake (2101/2701), particularly if used with long-tube headers. I'm hoping you used long-tube headers and not those fosdick shorties that are worthless for making power. All they're good for is to lighten your wallet.

Use a minimum 14 X 3 air filter, 14 X 4 is even better if it will fit....

Right after the collectors, add an H pipe or an X pipe. This will balance out the pulses between the left and right banks of the motor, add a little power and make the motor sound sweeter.

Pay close attention to the spark plugs and learn to read them. The motor may go a little lean with the higher intake, headers and being able to breathe better. If you used an Edelbrock carb, use this Owner's Manual to tune with....

Great, install the tall intake and then the H or X pipe and you're done on the outside of the motor. Further gains will require disassembly.
