Default 12's... Is it possible?

I ran my car last summer with the following mods.

CAI
Crank U/D Pulley
Pacesetter lt's
Or/y
Mangaflow cat back
E-cutout (same times open/closed)
Mad Z28 tune
4.10 Gears
Sumitomo street tires got me a best of 13.4 at 103mph with a 2.02 sixty if I remember correctly.

Now I will have the same mods except I'll also have...

1.6 roller rockers
LCA's
Relocation Brackets
Drag radials

I would also like to get an estimate with a Yank PY3400 stall. Im hoping to put down around 310rwhp but can I make 12's?

you can hope and pray and do religous things, make posts, whatever you want to do.

Just remember, not every track is at sea level, DA isnt always good, And track prep isnt always awesome (ive seen vids of peoples shoes tacking while they walk on the track...makes me goddamn sick)

Your looking at the edge to me, could go high high 12's, could go low low 13's. You definetly have a better chance with a stall converter.

Nittos are unpredictable as well, hope you got ET streets.

The relocation brakets and LCAs, with sticky tires and a good launch should get you there I think

If it will hook up just changing the tires is probably worth .2 sec. There is only one way to find out. Take it to the strip.

x2. 12's should be a piece of cake for what you have.
Why the ProYank instead of something like a SS3600? ProYank would typically be for a higher powered steep geared drag car, whereas this sounds like a street car.

Id say yes. Know your 60ft down to 1.8's and the added 10hp from the 16.'s will put you in the 12.8-12.9 range. This time of year with cool weather will help. Stall will help greatly. Id go higher then 3400 but for $300, thats a good deal. Im ready thinking of restalling to 3800-4000 and i just put in the 3600 lol

If the motor has good oil pressure and compression there's no reason you can't spray through it all day long.
