When it comes down to the basics is , that,we ALL tend to run into the same basic issue,
and thats the fact that we don,t have enough of the ready cash to dump into a project,
to just buy a complete engine. SO, we have to carefully plan how to allocate our limited finances.
now for a few basics.
your going to find your
engines DISPLACEMENT , the
CAM and
CYLINDER HEADS ability to flow air,
the
exhaust scavenging efficiency,the vehicles
WEIGHT, and the
DRIVE TRAIN GEARING,
has a good deal of effect on the car/truck performance.
the larger the displacement and the higher the compression ratio
do all the calculations and math you'll need to do,as to compression, port flow, cam timing etc.
WELL BEFORE you purchase components
(as long as the fuel octane will allow you too without running into detonation)
generally the LEAST expensive compromise, you may make, when you compare total cost vs available power,
will depend on what you have available ,
step back take a deep breath, and think logically, your not locked into using the current parts you have!
you might want to visit several local salvage yards and look for a deal on a complete basic engine,
if for example you could find a 396 BBC, a 383 mopar , a 460 ford or a 472 CADDY , in running and re-buildable condition,
for $500-$600 (which is not that hard in some areas)
yes we can easily show you how to build a kick ass 383, or 406,
but both options would cost more that rebuilding one of those,
if you bought the engine for under $600 and rebuilt it as your starting out with,
almost all the major components that might be re-usable
