What can I do to my old friend that will make it scream to 100mph. How much differance will 3.73-4.10 gears make 0-60. Could I see 4.9 sec 0-60 on a bone stock car or will I need to cam it as well? Should I just pull the engine and start fresh? The tranny is only 16,000 miles old.

It is a long story, however, I was able to purchase my first Dream car back today "the exact car". 14 years ago I had to sell the car that I had wanted all through high school and the Army because of a new job. The woman who bought the car babied it for the past 14 years puting on only 5000 miles a year. The car is a 1994 Z28 (LT1) A4. I have moved on to other high performance cars over the years. I am currently building a GTM what has a race weight of 2200 lbs with 410HP and my last "go fast" car was an E55 Renntech with 588 hp so I have gotten use to speed.


Thanx for the advise.

My 0-60 times diminished because she simply wouldn't hook after swapping in 3.73s.


Between my gears and the 3500 stall I put in a few weeks ago, mine has awoken substantially. I'd suggest 3.73s and a torque converter. With decent drag tires, you could gain up to and over half a second in the quarter mile without adding a bit of power. I don't know about 0-60, but your 60ft times will be awesome.


Congratulations on getting her back.

+1 on the converter. Does your car have 2.73s or 3.23s?

Not sure, but didn't the 3.23 gears only come in the SS? 5.6 sec 0-60 to 4.9 might be a tall order, but is it possible?

What was the cost to swap the gears?

if you want massive acceleration, 4.10's and a 3600 stall man!! but you will bake the tires everywhere and probably top out at around 115-120 in third with a 26 inch tire.

hey fellow cape codder, not sure on the price but hamliton(sp?) transmission is probably your best bet around here unless you know some one. they'll be rebuilding & swapping gears on my 10broke pretty soon.

Yes, a Street light queen exactly what I am looking for! Who cares about top end on "Cape Cod" however my GTM is geared for 204 top speed (will need more power to get there) but in its current form will still run 0-60 in 3.2, should brake into high 10sec quarter, top out about 190 and corners at 1.09 lateral G's.

I am looking forward to doing all the things I wanted to do to the Z when I had no money to do it.

Can I use any older style SBC starter on the LT1?

Speedfreak where on the Cape do you live?

Good lord, speedfreak! Did you try to outrun them?? I see the fail to stop for a police officer...Might want to try slowing down A LOT on the streets.

And I thought my 95 in a 55 was bad.

Any other thoughts on what I needed to brake into sub 5 sec 0-60? Also will any SBC starter work?

I live in Sandwich.

I was thinking most a4 z28's had 3.23's. Most shops around here will do the install for around 150 to 200.

That's only the M6 cars, the SS/WS6 A4's had 3.23's, as do most. If your shifter has a 1-2-3-D-N-R-P pattern, its a 3.23 gear car, if it has no selection for 1st gear, then it is a 2.73 car.

I would use the LT4 starter if you are in need of a new starter, its a better starter and you don't have to worry about fitment.

LCA's will help allot with traction and are fairly cheap, a tq arm will help too but are 3x the price. got good tires?
yeah..I passed a trooper doing 100+ faster than he was going and his headlights disappeared so fast I figured I might as well keep going(note my speed was criminal but failure to stop was civil). I left a few cops in the dust actually but theres no where to run on the cape so I eventually pulled over and got the gun in my face treatment. last time I'll do that, thats for sure...
I blame it on zac's(thats sandwich right?) it got me rushing home to get a piece.

Ok another question, should I get the ebay $3099.00 383 stroker or pull this one to rebuild. I am guessing with a stout cam and a .30 over should be around the same power??

What do the shops charge to rebuild if I bring them all the parts (including the heads?

Just looked it is a 3.23 geared car.
