a few useful links,
and sub links
videos, and tips
to look over
yeah, increased displacement helps and building a killer BBC old school,
for your car can be both cost effective and produce impressive results
some of the most effective, cost per hp and efficient combo's ,
will be the 496 displacement and if you have access to the correct block,
the larger bore 540 BBC combos.
nothings cheap to build but a very impressive and durable,
over the longer term, power plant can be built.
do the required research, and stick to a known well proven well documented combo.
both the 496 and 540 combos are built,
with the 4.25" stroke (FORGED 4340 STEEL crank )
and both usually use the 7/16" ARP rod bolt 6.385" rods,
and built for street performance use,
generally the 300-345cc intake ports,
both generally use the 10.5:1-12.5:1 compression ratio,
and are generally built with a cam in the 245-250 intake lobe duration at .050 lift range,
matched to a 3200 rpm stall and a 3.73:1-4.11:1 rear gear ratio
obviously do the required research before spending cash,
but 600-680 hp, and similar torque is not hard to reach or exceed, N/A
with proper planning, and parts selection ,and higher quality well matched components.
slap a turbo or centrifugal super charger on a well designed 496-540 bbc
and cracking 800 ft lbs and 1000 hp has been done frequently especially if supercharged or nitrous are selected.
I've built dozens of impressive 377-383-406 SBC, engines,
that powered cars into 11 and 10 second 1/4 mile times
but they are not even in the same league with the feel ,
or sound of a car powered by a high compression 496-540 BBC engine.
regardless of displacement you should try to get a BBC to produce about,
1.3 ft lbs of tq and 1.35 hp per cubic inch of displacement N/A as a goal
with correctly matched parts this is generally something you can achieve
reading links helps reach that goal
you should keep in mind every choice made is a compromise in some areas, planning is critical, but reality can bite you in financial the ass.
incremental gains through minor mods while surely possible and yes proven, to work,but adding those mods,
are at some point ,mods to the engine,or transmission, that are becoming rapidly more, expensive and thus restrictive to completion of a durable & functional engine than the benefits are to the overall build, those mods may produce minor and documented gains, but the minor gains produced are far out weighted by the cost of the mods, especially in a daily drivers engine, things that make sense in a formula 1 or NASCAR engine build, are cost prohibitive to do on a street car, simply shedding weight on the car or improving the aerodynamics, may be far cheaper and result in greater performance.
I've built a few dozen 489-496 BBC engines in the past for guys with novas, camaros chevelles etc, that had visions of having a 10 second or faster car on the street, and the results of having a significantly more powerful engines always resulted in the need for mods like suspension mods,
like traction bars, air shocks, bigger tires, bigger brakes, better engine cooling systems, new stronger differentials, etc. that they may have never considered, that were required to make the car handle correctly, this is never a cheap hobby, but at some point there's a limit to what your wallet will tolerate and how long you want to deal with a car who's engine is (STILL UNDER CONSTRUCTION SO I CAN'T DRIVE IT YET)

building a potentially impressive BBC
think twin turbo/ intercooled /e85/ 1300 plus hp with added oil cooler etc. think of this as a quick way to blow $33K minimum :facepalm: :like: YOUR CERTAINLY NOT GOING TO BUILD SOMETHING LIKE THIS AND EXPECT IT TO RUN ON THE LOCAL GAS STATIONS PUMP LOW OCTANE FUEL heads...

what to look for in a "GOOD" engine combo
I got asked , "what makes a GOOD vs A poor engine combo?" and without getting into specific combos , too deeply, lets look at that question like with most performance parts and applications the critical part of the build, is generally in selecting the correct components for that particular...
