Just wondering who would win, a 85 trans am that has a full exhaust work and a single plane weiand intake with a cc-q-jet. Also has 3.23 gears and stock 700-r4.

I wanna know if my buddies 91 LO3 camaro that has K&N air cleaner and a cat-back can outrun me?

He says that his car will blow my doors off the Trans am.....this true? Also a punk driving a 92 3.1 camaro thinks he can run me down......

 

you got him. i own an lo3 car that runs pretty decent for stock and the best i hit was a 15.65. cept for the posi and open element it's stock. those l03 heads are crap just like the rest of the powertrain in those cars.. takes ALOT of supporting mods before they can make any power(fuel pump for example, PITA in our cars!)

 

You should take them both.

 

you will wax that ***, lol im doing pretty good with a 305TBI, but it has ALOT of mods, ran away from a close to stock TPI............ i will tell you what will **** you off.............there is some chick here that daddy buys her RICE but she has a Lexus with an *** ugly primer body kit and wing, but she has twin turbos and is spraying..........LOL i told her, let me spray and put some gale banks twin turbos on mine and then we would play, she got the camaro and the honda (honda is a 2006 Vtec V6 accord), but i will say i ran good with her givin all she has done, and im all motor N/A

 

okay cool i can just collect money from them then lol.

Today while working on the 85 trans am a 15yr old kid i know comes to me and tells me bout his 1984 GT350 rustang and how it will eat my car alive! His car is rotted, a "ho 302" and a t5. I think even if he can outrun me now....he'll blow the t5 because hes teaching himself how to drive stick

The reason i quoted h.o. 302 is the previous owner went though 3 different junkyard motors and i doubt its a high output.

The car has dual exhaust from headers,a big a** holley, no brakes, rotted floors, rooted doors........ya think if he gets it driveable a GT350 302 can outrun me? Because i cant find specs on how fast it is stock!

 

I think you will have the most difficulty with the L03. They were rated for more HP/TQ stock than you are. Your 3.23 gears also don't match the powerband of a stockish LG4. The single plane intake is going to kill torque off in your car without really doing anything up top. You can thank the tiny cam in the LG4 for that.

 

okay UPDATE!!!!!

i took off holley intake and went to stock dual plane quadrajet setup.....car hauls a**! I ran a lo3 few days ago and out ran him no problem! The one i want to run is just got a catback basically, as i have full exhaust open element. He has a swapped rear end also, its a 3.08 instead of stock one.....so im guessin no problem at all.

I still cant find out how fast the kids 1984 gt350 mustang is? anyone have a clue? a 302/T5

 

If you're looking for a good working LG4, the combo below in my signature might give you some ideas. Changing the intake back was a great idea, you'd need a lot of cam, and better heads, to support a single plane.

 

with that much work done to your lg4, what does it run in 1/4 mile?

 

Going this weekend to find out. I've got an intermittent fuel starvation problem, so I might not get a full pass out of it, we'll see. I'm best guessing, based on street races with other vehicles with aprx known times that it may pull about a 14.7, or a slightly better. Its a mean holeshot car, it destorys lots of rides off the line. You've actually encouraged me to post a hypotherical "What will it run" post.

 

I ran a zx2(wife's car)(turbo) v/s a 4th gen V6 with exhaust and smoked him from 30-90. they stopped for gas and I only lived a mile away and went and got the T/A and smoked the same 2 clowns again. This time with a LG4 with exhaust and performance filter.

1/2 car with the ZX2
3 cars with the LG4

Ran a 92 LO3 camaro and got him by a car.

Those V6 guys think they got something when they stick some glasspacks on a 6. There is a couple 6's that I won't even touch until I get the 355 installed, its all in the mods

 

I have an 83 TA with LG4 and T5 with 3.73 gears, and a 90 Bird with l03 and T5 with 3.08 gears

from a dig up to about 60 the Trans am is faster, but from there to about 100mph the Bird was faster. But top end umph still goes to the TA. My TA pulls pretty good from 100 to about 130mph. The Bird pulled good till about 110, then had a really hard time going any faster.

Honestly I atribute the differences to the gearing. The 3.73 gears were definitely better than the 3.08's. But I was surprised that in the mid range the 3.08s seems faster. I have a vid of each car, one is the TA just short of a 1/4 mile, and the other was up to 110mph. I'll try and post the two

Both cars were basically completely stock other than the cat being gutted on the 90 Bird.

I shoulda got my g meter out and tested both, but both of my cars are all tore apart now so its too late...lol

 

What gave your trans am that sound? I LOVE IT! that power bulge hood sound?

I REALLLY need to get an 3.73 gear setup or better.......i want a t5 or super T-10 car bad too.....i hate autos. Every car and truck ive owned til now has been stick

 

When I got the car it had a Holly air cleaner which I think was what I had on the car at the time of the vid. But that basically makes it sound like it has no cleaner at all. I dont recomend that cleaner which I think was called the Powershot, or something like that. Mine ended up catching on fire and nearly burning my car down. Those things are dangerous. But after I got my bulge hood functioning again(didnt work when I got it), and got the correct air cleaner lid, the car still has a similar sound to it, but not quite as loud. When the vid was made the secondaries were not operating properly and were opening too fast, so thats the sound you probably like. Once I changed the carb to a mechanical q-jet and got it tuned good, the sound is still there but not as loud due to the secondaries operating properly.

But I will say that the power bulge hood definitely lets you hear the carb. I love it too. I'm gonna hate losing it when I install the LT1 engine that I have. I actually considered using the carb intake on the LT1 just to keep the hood functional, but that would defeat the purpose of having an LT1...lol

 

are you going auto or 5 spd with the lt1??? Also, lmk if you are going to sell the pwr bulge hood.....im trying to find one at a decent price.

 

I will stay with the T5....for now, I'm sure I will break it, but I'm gonna try and keep it together for a while. Then I'll get a T56. As far as the hood and parts, I'm not sure yet what I'm gonna do. I'll keep ya in mind though.

 

okay cool. i found with the t5 if you dont "slam shift", launch hard, or any stupid stuff they last a while behind decent sbc's. My buddy is doing a lt1/t56 swap into a 84 trans am....fun stuff. Its the little things that get to be a pain.

 

yea while i REALLy want a stick shift, i REALLY like having my trans in one peice, stock t5 is a no no. for TPI's power band i think my 3.23's and a 4 speed would go well together. problem is finding a 4 speed that fits in an f body grrr...

 

get an aftermarket torque arm and mount, and then you can use whatever transmission you want.

 

look for 82 f-body 4 speed Manulasetups...possibly 83 too. The stock tranny isnt too strong i heard(better than t5)
I plan on trying to get a whole 4 spd car and converting my 85 t/a over......i cant imagine....383 tpi car w/lt1 intake....mated to a oldschool 4 spd!
That is my realistic dream car!......un realistic is a lt1/t56(with current job)
