To run some better 1/4 mile times ? I could care less for the track, I need to kick *** on the street. I was thinking a pair of AFR195s and a miniram. Or build a 406 with 195s and a miniram. What would you guys buy to get it in the 12s ?

I'd say heads would give you the most performance gain. Better get an intake and larger tube runners to feed those heads. Then work on your suspension, gotta put the power to the ground. Maybe some transmission upgrades, quicker shifts = lower times!

Blade,

You didn't mention rear gear ratio, but unless you're running 3.73s or higher, a torque converter swap can provide a lot of gains in accelleration, and doesn't have to cost you a lot in fuel economy if you retain the TCC. You'll have a little cash left over, too.

Guess I should have said what mods I have already. Hehe

I have a 2500 RPM convertor, a new "race prepped" transmission that has very positive shifts, and I have the stock 3:23 gears. No suspension mods whatsoever. I figured if Traxion's IROC can do low 12s with the miniram/AFR190s combo and considering I have the exact same cam, I should be able to pull the same times with some suspention mods.

I might be going against the grain with this one but i thinkthe miniram is way overpriced for the performance it delivers compared to what else is out there

I think youd be further ahead to get a single plane conversion, afr 195s or GMPP fastburns and the aformentioned cam

im sorry there was no aformentioned cam lol i was seeing things

 

my recipe for 12's are as falows. 406 with 10:1 compretion, Comp 282 solid cam (.495 lift 236 duration @.050). eather camel hump heads, 292 turbo heads(if my friend gets them from a car he is planning on buying) or 993,441 heads, obviously they would be ported
perfromer RPM intake with a holley 650 dp, headers, 3inch exhust, 700r4 with vette servo, 9 clutchs and shift kit, with 2400 stall converter. 4:10s posi. my fried garented me 12s( same friend wanting to buy the car with 292s)

------------------
when the green flag drops the bull$hit stops

Curent: 350,performer RPM intake ,650dp, 700r4, headers, 3inch exhast
Spring 01: 406, Comp 282 solid cam, 2400 stall converter, every thing else the same.

 

3 grand? Price of a Vortech TPI supercharger kit.. random idea from the peanut gallery.

'86 Camaro SC, black /w silver racing stripes
MSD coil, Accel 8mm wires, SplitFire plugs, Gabriel hijackers

 

Well I want to stay N/A. I know slapping a supercharger on is the easy way out but I dont want to do that. Also I want to stay fuel injected. So a superram or a miniram is probably the best choice.

I'd have to say an ATI I know its the easy way out but it beats ripping apart a good running engine. Plus u know and ATI is guarenteed power and it's probebly best bank for the buck (NOS not included)

 

...with 3 grand you can "blow" anything...
LOL

-K&N Airfilters
-Ported Plenum
-2.77 Gears (not much to brag about but eh, its there)
-MSD 8.5 mm plug wires
-Problems every other day with the car (probably not a mod, but to me it sure makes a difference)

 

Hell, you're almost there already, just tune what you have.

Hotchkis LCA's and Adj. Panhard Rod
SLP weld-in Subframe Connectors
Lakewood Airlift Kit for right rear spring with between 10 and 15PSI in it.

Remove front sway bar at the track

BFG or Nitto Drag Radials

3.73 gears with an Auburn Gold limited slip

LT4 Hot Cam Kit w/1.6 Roller rockers (comes with the kit)

If you still have $1000 or so left over, Trick Flow heads and 30lb injectors with an adjustable FPR.

Anyway, that'll get you there.
