No Fear just remember if your gonna build a
practical street motor.Those Huge Heads and radical camshafts are useless as tits on a Bore hog for practical street use.,,,and then trying to ad NOS on top of this for practical purposes is good for nothing but conversation pieces.
the advise i been reading your getting is AWESOME for Race engines...or Racing in a STREET CLASS....but not hardly for something you would load your family in and try to make a 100 mile Journey to the Zoo and back.
Just giving u my opinion from the past.......
start with a good GM (UN-BORed) 10:1 compression block shoot for the 454 to 468 ci...use a set of Bowl blended ( only) bb2 brodix or Afr's 2.25-1.88 valves...700 -720 LIFT range hydraulic roller....port match your intake ( only)..
with right carb this will get you in the 650hp ( maybe little more) hp range...More then enough for the street.....if ya wanna to be a little different...take the extra grand you would have spent on the dart block and buy you a 177 bm low profile blower.....drop compression ratio, change to blower cam, use a cometic head gasket
again just my opinion......orrrrrrrr Build you one of these 1,000 hp engines with all these HAWG parts and call it a street motor and drive it to the end of the street and back twice per year.....lol
