Every little bit helps & adds up
sometimes it's cheaper than engine performance
especially when you get into the low 9's & 8's or quicker
it snowballs 10 fold getting into the low 8's or 7's
after all it's about HP to weight ratios
especially with these heavy B-Body cars
nuts bolts washers
aluminum Carbon fiber fiberglass titanium
replacing cast iron or steel
alum bumper brackets
composite bumpers
Lexan windows
glass/composite doors, hood & trunk
alum rad, water pump
electric fans & pumps
cell vs ol' fuel tanks
racing seat vs heavy OE stuff
carpet, back seats & undercoating/sound deadening
brackets, dash, gauges, understructure, window regulators etc.
anything anywhere it all counts up
anything anywhere helps
moving the battery to the rear helps a ton weight off the nose
& behind the axle where it works for you
even rotating mass helps a ton, especially on track performance
driveshaft, wheels, tires, brakes
tubular & chrome-moly parts vs heavy stamped steel
it's 40% of the weight of steel better in strength too
etc. etc. etc.

Some stuff is much easier & better than others,
some is far more costly than others too...
Money & time spent is relative to going fast,
how fast you want to go & how much your willing to
commit time & efforts for seemingly little to no gain at times,
the time spent to do it, will be reaping benefits in the final results,
shows how much you were willing to commit, they go hand & hand,
it's either really hard work & very little money {that's a fat chance}
or really a lot of money & just a slight bit less work...
Chose your path, spend it now or spend it latter,
if you want to go fast, it will take it from you sooner than later,
all relative how much time & $$$ spent, will dictate/determine
"how fast you really want to go ultimately"....
Been there done that !!
Old saying "Pay me now or pay me latter" comes to mind
you will pay both in time or $$$, if you want to go fast...
