Lets get back to reality .. the OP wants to go MID 9s
in a streetcar... I will assume on premium pump gas...
OK... lighten the car to 2800lbs-2900lbs... thats not
that hard from where he is(IF YOU SPEND SOME TIME)
so if he has that weight... 620HP will do it.. for
the street I would run OD... GV is a real nice set up
but cost $3000... I went with a 518... bolts to a SB
without anything.. cost me... $300 for the trans (at
the bone yard), $110 for the freshening kit, I changed
the input and pump so I could use a non lock up high
stall conv $120(for input and pump)... thats it for
the trans.. a 4.10 gear and I went with 295/55 tires..
once I dial it in should be 10.0 or a bit quicker
but I dont have 620hp.. I have 550hp and this should
be a decent street machine(I will see next spring)
LIGHTER IS ALWAYS BETTER
