The lt4 hot cam kit with a tune or a set of longtubes and 4.10 gears on a 1994 z28?

 

4.10s in an A4 is a bit much if it's a daily driver. Most stick with the 3.73 when using an Auto.

I would say Stall and a Tune, or Stall and Headers.

Or even Stall, Tune and Headers Not sure on the Kit price, but I'd think a stall would be less than the kit, so the savings can be used on the tune.

 

is an m6 that currently has 3.42s

 

Ah. I was going off your sig.

I guess if it's not the car in your sig, it would be better to list what all is done to it.

 

lol...guess that would help a little...my bad. 1994 z28, m6, cai, tb airfoil, ory, flowmaster exhaust, fresh tune up.

 

Ditching the Flowie would help a fair bit. I say a better muffler, headers and tune.

 

LT Headers & Ory, Magnaflow cat back, cam & tune & that will be a whole new car.

Now i'm running a 97 M6 with 3.42s, after the LT headers install with Ory (eleminating the cats) it picked up so-so, but the torque was VERY noticable down low, a cam/rocker change in mine would spell wonders i'm shure, but you really need a good flowing exhaust to balance things out & benifit a cam, plus at this level, a tune is VERY benefitial, so bottom line, do the exhaust first, but IMO, the cam/rockers are worth more power, but without the exhaust, you'll be putting the cart before the horse.

As for a gear change, i myself wouldn't put a penny in those 10 bolts with an M6, thats why i upgrated to a 9"

If you want the cheapest HP gain, throw an NX base system on it, easy 12s & over 110 MPH with what you have.

 

I'd go LT's and tune
