3.73's (3.90's or 4.10's not out of the question)
Crower 15513 camshaft (.512/.531 lift; 228*/234* duration; 112* lobe center)
~3300 lbs race weight
I don't see it getting 120mph, even if it were 3000 lbs. The cam is a little on the small side and the compression is a little low. Get it to 11:1 with a bit bigger custom cam and at 3000 lbs it'll do 120-124 or so (as a 5 speed).
At 3300 lbs, you're going to need the compression and the cam to pick it up, full suspension setup perfectly, and the gear setup to match the cam and a good driver.
My old setup went 119.5 through an auto at 3050 lbs:

Lunati 51012 cam 544/560 232/242 112 lsa
Holley Systemax lower port matched to heads
75mm t/b, 30 lbs injectors, 77 pro m maf
1 3/4 longtubes to 3" exhaust
3.73 gears and 28" tires
4400 rpm stall speed
with a 1.53 sixty foot was the best n/a pass. It would have gone faster with a custom cam.
As far as being streetable, a custom cam will get you that and good power. I just don't see it running more than 115 at 9.5:1 compression even with a custom cam.
