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
obviously as time passes , newer and better parts become available and knowledge advances, so take the time and effort to research the most current info, and yeah, better parts tend to cost more money, and yeah this is an expensive hobby, but you can save a significant amount of cash by doing a great deal of research before you purchase parts and by doing much of the assembly and clearance work, owning and knowing how to use precision tools, and checking fit, finish work yourself
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 , theres several great heads available, your choice is mostly dependent on your checking account balance and your personal mechanical skill and knowledge, on how you select and assemble a valve train.

but your almost always faster with the 406 combo because the slightly higher average torque curve.
I've 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.

carb

match too 8 quart baffled oil pan that fits your chassis, and Competition headers with 17â„8" primaries,37-39" long and a 3.5" collector 18" long
personally Id use a vertex magneto ignition , figure oil pan $400

THIS IS DYNO SOFTWARES WILD GUESS ID BET I COULD TWEAK IT TO GET A BIT MORE FLYWHEEL HP
heres the same engine with a 100hp worth of nitrous

MISCELLANEOUS COMPLETION PARTS FIGURE $2800 more
so a really nice SBC combo making near 750 dependable hp in a similar combo costs about $13,300
heres what might be a better option
