I'm thinking closer to 16 sec.

Lower tire pressures will work with drag or street slicks, but not with normal street tires because the sidewalls are too stiff.

EDIT: Also, the rubber they use for slicks is different than that of street tires.

im gonna say 15.3-15.7 only because i ran my factory '84 LG4 (150 hp 240 tq) car w/ nothing but flowmaster catback and ran 16.1@83.6mph. this run was done nov. 2003 in perfect track/weather conditions. i even did a burnout w/ the 2.73 open diff... lol... anyway, i had owned the car almost 2 years myself and never replaced ANYTHING but oil.... could've been running on 7 cyl. who knows?!!... go for it man!!

if you can plumb some raim air for that dual snorkel i'd do it... check out a local HVAC center for some tubing... or to get ideas www.ramairbox.com

Well the L69 pushed the monte carloSS down the strip at a 15.7 so im guessing a 15.5-15.7

you should be able to get mid to low 15's.....i got a 92 rs 305 tbi auto....all i got done is full exhaust...open element air cleaner...junk jet stage 2 chip....throttle body spacer...and 3.73 gears and i hit 14.8....and that was with my timing retarded 12 degrees cuz my friend messed it up....so thats not to bad for a lo3 305
