BASIC COMPONENTS, obviously you don,t have to use the exact parts listed but the more you change things the less likely you are to have near the same results, and with you doing the assembly and careful shopping you might bring the price down slightly on either build

after building DOZENS of similar 377 and 406 SBC engines, over the last 40 plus years and seeing what works and how the newer aftermarket heads far exceed the older stuff we used to have to use,for those engine builds, guys I can assure you that the peak hp will remain rather similar if both engines are built to similar specs ,
but your almost always faster with the 406 combo because the slightly higher average torque curve.
Ive tried dozens of combos , but keep in mind your drive train gearing and car weight and converter stall speed and if you have an auto transmission, and need to pass emission testing, and if the combos injected or runs a carb, and if you want to run pump octane fuel or race octane gas ,obviously effect your choices a great deal.
two common mistakes are not having a low restriction exhaust and well designed headers and having the wrong cam for the compression ratio and gearing
but the most common seems to be buying restrictive heads and intakes, if your looking to get a 377-406 to peak power levels,.
the combo below is obviously not meant to be a daily driver combo, that runs on pump octane swill.

SAFE piston speeds are best restricted to 4000fpm for stock components and 4500fpm for the better common aftermarket components
