worlds motown intake,world sportsman cast heads 72cc 200cc intake runners,jw 4500
stall convertor,kieth black dome pistons .105 domes.car wieghs
3300 lbs.the headers are 1 3/4 primaries,
with the 5.14s i was crossing the traps at 7200rpm,thats why i
changed the gears now im crossing at 6200.
this is just really starting to puzzle me i figured i would see a change
one way or the other.
the only thing i havent done is head work planning on doing that this winter,plus when i started this build it was gonna be a street strip car so i also put .051 head gaskets on to keep my comp down.
if i change my head gaskets to a .035 and do some major head work does anyone think this will help?
my goal for next year is to run in the 6.90s any opinions on how to get there would be nice.
i realize most people wouldnt even be complaining because my car will go out and run a 1.61 60 ft,7.66 or 7.65et every pass,and thats how you win races but im just wanting to go faster.
