Built Small Block 350 400HP Engine In The Camaro Project!

FAQ

In this case, chump change meant building our small-block with a ceiling of just $1,000. Given the fact that $1,000 is nearly the cost of a set of most aluminum cylinder heads, reaching 400 hp for a grand total of $1,000 looks pretty impressive-not to mention somewhat difficult.
a typical 350 Chevy can make upwards of 350 - 375 HP before you exceed the reliability of the components. For a big block with the same stock components it can make in the area of about 400 to 475 or so HP and handle upwards of about 500 HP before you exceed the reliability of the stock cast pistons.
With the stock Vortec heads, the low-compression 400 managed to make 376 hp and almost 450 lb-ft of torque. Summit piston rings, std. While this total may seem expensive, it is a true accounting of all the costs incurred including carb, ignition, and headers.
Two-Barrel Carb to a Four: Upgrading your Chevy 350's stock two-barrel carburetor to a four-barrel, like a Holley 650 double pumper, is a great way to add more horsepower. This swap increases air and fuel intake, directly translating to more power.
You “can” get 500HP out of a 350 BUT because it is a small cubic inch engine it IS going to be peaky and won't have much torque.
