see sig for mine....I am sure I can get mid to low 13s when I install the SLP CAI, ported plenum/runners and a 52MM TB.
I am running a untouched shortblock (55000 miles) and stock cam and on street tires.
There is alot of potential with these heads.

Check my Sig
It still needs tuning but it is showing lots of potential.

Hey Dyno Don....how is the ZZ4 cam? What I want to know is how it idles, vacuum and such.
Basically I have stayed with my stock L98 cam to maintain as stock a feel to the engine possible, but might consider swapping in a ZZ4 cam. Do you have the specs as well?
Did you see a big improvement from the runners?

I'm interested as well, Dyno Don, I'm in the building stage of a 355 with vortec heads and a zz4 cam, 1.5 rockers though. Curious as to the manners of that combination. I'm using MAF, so if the idle is tame, probably not looking at alot of prom tuning.
Also, what kind of suspension mods are you running, thats a decent 60' time you've run, 1.7. See alot of cars running in the 2.0 range.
thanks!

Haven't ran it at the track. I'm figuring it runs mid - low 12's as it sits. I am judging that by car's that I've beaten in 0 ~120 street races and from a g-tech pro comp.
I run 11.8's - 11.9's on a gtech in the car's current state. Add a few tenths to what a g-tech shows and it's pretty close to what you'd run at the track.

Leave 1bad alone! Are you the origninal poster? No? Then keep quiet - 1bad has put a lot of time and effort into that car and he IS posting a G-tech estimate. Back off. G-tech IS near actual ETs.

The ZZ4 has very mild manners (208-221 @ .050 and good vacuum) Very good improvement with the runners.
The car has boxed LCA's & PH rod, LCA Relocation Brkts., with the after market Tremec 6sd. I had to shorten the driveshaft and the torque arm 2". Before that I was cutting 1.9 60' times on E.T. streets.

Those are some nice ET's, I'm excited! I can wait to finish the motor and go for a spin
I ran my GTA at the track in basically stock trim, and it pulled a 14.74 @ 92 MPH. The motor and car have covered 57K miles since new.
Mods now in progress on my 89 GTA are:
- Comp Cam Xtreme XR264HR-12, 212 / 218 @ 0.050, 0.495 / 0.502, 112 LSA
- Comp 1.52 roller tip rockers
- L31 "062" Vortec heads, fitted with 986 Comp springs etc and machined for 0.550 lift
- SDPC base
- AS&M LTR's
- Fully ported stock plenum
- Headers (1&5/8 inch)
Poncho, your ET is very impressive for the mods you have completed. Hopefully with my setup I will be saying hello to the 13's as well....

GTech is not accurate from what I've heard. The only thing that counts is actual track times. Now you might not agree but bench racing is for amatuers, and 1bad91z seems not to be one.
I am and have been for a long time interested in the performance of his car. I just want him to run it already.

First off, the g-tech comp pro is "close" to actual track ET's. That's why I added 4 to 5 tenths to my g-tech time and I said the car "should" run an actual track ET of mid - low 12's as it sits now. That's not "bench racing", that's a fair and pretty acurate statement.
My combo is a little more stepped up than Mike Crew's combo that run's 12.20 (track time)
My heads flow better, I have a bigger cam, I have more compression, and my car is lighter than his.
He has a 383 to my 355. But, both are vortec headed TPI motors.
My stock G92 rear is on it's last leg and I don't have the money to fix it (I'm saving up for a 12 bolt). And the nearest track is over 2 hours away from me!
SO, if my track times dont come fast enough for you guys, then you are more than welcome to give me MONEY to make things happen when you would like them to happen.
I would love to have my car track ready, and when that finally happens, you should already know that I will be posting the results!
Peace out.

BAD91Z, I DON'T THINK ANYBODY IS TRYING TO TALK TRASH HERE, AND NEITHER AM I, BUT, I BELIEVE, THAT PEOPLE ARE JUST ASKING YOU TO NOT GIVE YOUR IMAGINED (G-TECH INCLUDED) TIMES UNTIL YOU HAVE COLD HARD PROOF. IT IS OBVIOUS THAT A LOT OF TIME AND EFFORT HAVE GONE INTO YOUR CAR, BUT THE ORIGINAL POSTER IS NOT LOOKING FOR ESTIMATES, HE WANTS DOCUMENTED TIMES. I DO NOT HAVE VORTEC HEADS, AND AS SUCH, AM NOT GOING TO POST MY TIMES. I WANT TO POINT OUT THAT I HAVE A DEGREE OF RESPECT FOR YOU AND YOUR OPINIONS, WHICH SEEM TO BE PRETTY MUCH SPOT ON, BUT I, MYSELF, LIKE TO SEE REAL TIMES. I RACED MY FRIEND'S TORINO (780 RWHP) ON THE LOCAL AVE AND AM RIGHT THERE WITH HIM STOPLIGHT TO LIGHT (ALMOST), BUT I RUN 12.40'S (AT THE TRACK) AND HE RUNS 9.40'S (AT THE TRACK). OBVIOUSLY, HIS CAR IS TREMENDOUSLY SUPERIOR TO MINE, BUT I CAN HANG ON THE STREET (TO A DEGREE). TIMESLIPS END ALL DEBATES AND SPECULATIONS. I EXPECTED TO RUN A 12.0 OR 11.9, BUT FELL SHORT. YOU LIKE TO COMPARE YOUR CAR TO SOMEBODY ELSES, BY SUGGESTING YOU HAVE A SUPERIOR MOTOR (IN THEORY), AND I'M NOT DEBATING THAT, I'M JUST SAYING THAT UNTIL IT IS PROVEN, HE IS FASTER THAN YOU.

1Bad, if you want to set up a fund to get some numbers on your car, I'll paypal you a dollar. Get a bunch of other members to do the same and you'll be able to shut all us "non-believers" up.
Hehehe....sorry dude, I couldn't help it.....

heck...I'd pay him 1 buck to actually get the car to the track...count me in
By the way, on the street I usually pull on my brother with his Vortec headed 81 Zed, yet at the track he runs 103+ mph easily 3-4 MPH more than me. My car simply puts more power to the ground on the street than his does.
He!! I even beat him at the track one time and he still ran a faster ET + MPH than me...I just killed him on reaction time and he never recovered.

You guys are funny!
It's gonna take more than a few people chippin' in a buck! lol
I seriously doubt I could raise $2,300 for my 12 bolt !!
You guys are just going to have to be patient. Believe me, noone here on thirdgen.org is more anxious than me about wanting to finish my project so I can take it to the track.
The crappy thing is that responsibilties come first before the toys. But hey, if my car had a shower in it, I'd be well into the 10's by now!

go buy a one legger from the boneyard for $75 and weld the spider gears. I think you are wrong about the gtech. a car like yours would run a faster time at the track vs street. The common street can't hold a beast like yours. I'm sure your car is faster than mine and I spin the tire at 85-90mph shifting into third. I have 295's on the rear.

I have gone 12.40's on my 80,000 mile original engine and tranny. Since then i have added 24# injectors, Walboro pump, new trans and a converter...and a new motor
The car was EXTREMELY lean through the whole pass. (pump died shortly after)
Also this was on stock trans and converter AND crappy tune.
Now, with the *** fuel system, good tune, converter and trans, I'm very confident in an 11 sec pass.
Havent run it at all with the new motor.
However, on bottle, i blasted a 10.87 run with old set-up. (150 shot and Hoosiers )
Looking for 10.60's or better on new set-up

I haven't updated my sig so everything in there were the mods at the time.
This was on my 80,000 original engine (350) and with stock tranny and converter. Also, stock injectors and pump.
One more thing, last night i was watching my old tapes and i lied about my BEST pass being a 12.40.
On a pretty normal afternoon, i managed to click off a 12.22 @ cant remember mph.
I saw that last night ad though to myself "g o d d a m n!"
So, 12.22 so far on the old motor

Re: Best Vortec TPI ET's?
Heres my best but it is its only time to the track and I feel it is nosing over on the top end.
12.851 @100.914, 1.694 60ft
Mods:
355, Ported Vortec heads, ported vortec SDPC base intake, mega-ported SLP runners and plenum, 58mm BBK TB, Comp Cams 218/224 528/536 cam w/ 1.6 Pro Mag RR, custom 1 5/8 headers and 3'" exhaust w/ Flowmaster crossflow muffler, 2800 stall, 3.23 gears, chip burned by PCM forless, afpr, and 30lb injectors.
Not a bad time but I have had stock L98's with similar mph in the 1/4 so I dont know what is going on up top. If anyone has any ideas, please share with me.
