what trannys are we talkin, mtx vs mtx or something else

iroc-z's came about in 85 i think and 85 n 86 they had 5.0s thats were pretty crappy

87 i think they had the first 5.7 in them and that was pretty fast posting sub 6 0-60 and mid 14's...

so, depending on year and engine, i'd vote for him

If you get him off the line (a good drivier should) you should be able to hold him off in the 1/4 mile, if not stretch him out a car length or more. But you should definatly take his automatic out of the hole. Of a roll it will be close.

Good luck, and tell us how it goes.

What are you smoking:rolleyes: ? I have both, an 87 black Iroc-Z Automatic 5.7TPI, and a 93 LS MTX... 8cyl automatics are way more powerful, and quick shifting than our wimpy v-6, and 4-cyl autos... It is actually an advantage by having an automatic in the Iroc because while your shifting hes going to be straight pulling from you, all hands down. Although you may have a chance if his Iroc is pretty beat up, or missing two plug wires, but I dont think so.. My Iroc stock ran a 15.13. With a 1500Rpm stall converter, shift kit, headers, exhaust, intake, and chip, it ran mid 13s... My Mx-6 ran a 15.92 stock... My point being be-careful, just because its an automatic doesnt mean anything, 700r4 transmissions can be nasty:shrug:...

You could always act like your interested in his car (everyone loves to hear people having interest in something they own)and make that quick move to pull two of his plug wires off})...

Depending on what year iroc-z28 you are talking about, my friend has the 1989 5.0 in his with a automatic and I killed him (bone stock) in my 6 by 1 car length, then I modded and kill him by about 3 car lengths. What most people don't know is that there was only one year 5.7l iroc-z28's came out and that was in 1988 and from 1986 to 1990 a few were supposed to have been made under the engine code 1le as opposed to the code l98 from the 88 model 350. Being a 87 actually puts him slower than a stock mustang 5.0 of that year. You are racing a high 15 sec to low 16 sec car, the trick to winning get him off the line. Even better, do a top-speed race because the gearing of the iroc is crappy an you will DEFINATELY win in the top-end. Don't worry I think you will do better than you think.

Engine code:8, RPL # B2L, with the added option Borg Warner Rear code:4EU, the car color: black, and the interior: black also. The car was pretty much very few of a kind. I purchased the car from the ORIGINAL owners son for 1500.00 who had the car in his garage for six years after his father passed away. I do know what I am looking for being as I am a mechanic (A-tech to be exact) and have had more vehicles than most people can count...Get this 67,000 ORIGINAL miles...

The really rare 1LE is the 5-speed one which no-one actually has documentation of just how many were produced...

Unless he has a Posi rear (which you could tell by disk brakes in the rear, unless he has a locker) I doubt he will get to good of a start on you, it will most likely be a one legger with a huge burnout everytime he tries to accelerate hard, But do be careful if he knows what hes driving... If he pulls ahead on you I doubt you will have much of a chance catching up, but it is possible. You could always throw some giggle gas in your car, just for safety measures, and if things get out of hand, you could just let him have it...:shrug:

More than likely you'll get him mid to upper RPM.

One thing about the TPI is just that, it's tuned port. The peak efficiency is 3600 RPMs. Because of that, they fall on their face at ~4500 RPM. TPI would have been a better option for trucks. ;)

It was originally designed for the 305 to increase low RPM grunt since the 305 doesn't have any. Once GM decided to use the 350 again, the only change was the timing tables, fuel maps, and larger injectors.

They used the same size TB's, upper plenums and runners. It was already choking the 305, but they were feeding 45 more cubic inches with the same air flow. Not good for upper RPM HP at all. :shrug:

The 700-R4 tranny has a first gear ratio of 3.06:1, which is very deep. If he can grab traction he'll kill you off the line. The downfall is the 2nd gear drop to 1.63:1. That's nearly half of the 1st gear ratio. The TPI is actually needed to make up the difference. Upper RPM is where you'll have the advantage.

Grabbing traction shouldn't be a problem for him since 90% of IROCs came with posi. The rear end was actually built by Borg Warner and is a 9 bolt posi w/ rear disc brakes. The ratios were a 2.77, 3.27, or 3.45. Depending on which he has will also determine how much traction he'll get.

Regardless, if his is 100% stock, then he should run mid 15's even with bad traction. It would be interesting to watch, I can tell you that.

About 2 weeks ago in the evening on the way home i raced a new z28 automatic...i had him until 70mph, after that he passed me...my car has just intake, plasmablaster, venom 400 performance module and iridium sparkplugs...but i had at that time a way over due date oilchange and soon to be blown off, really not sticky tires...so i think u can try

What about a 93 5-speed manual MX-6 LS
VS.
1979 and a half Camaro Z28 4 Speed Manual


I think i know what the outcome would be... Anyone have any input...

I am pretty confident you could take him if he is bone stock, most muscle cars were mid to high 15 sec cars while a few were 14 sec cars and some were even 16 sec cars. So if you are a good driver and can lauch then you have a fair chance. If you mess up the launch then he mgiht eat you up due to the fact that once hes going hes gone its launching that hurts him.

New Camaro? If you mean 98 and newer, those had the all mighty LS1, that pushes 315 hp and 350 ft tourqe. I don't think any MX-6 with all the bolt on's possible (excluding FI) has a chance.

Even the 93-97 had the LT1 that ran mid 14's all day long w/285hp and 350 ft tourqe, their top end isn't nearly as good as the LS1 though.

That car doesn't exist. No such thing as a '79 1/2.

And if it's a '79 & still stock, a '93 MX6 will waste it.

1979 was one of the heaviest Camaros built and the most powerful 350 was 170 HP @ 4000 RPM/ 270 ft.lbs of TQ @ 2400 RPM. 8.2:1 compression.

Everything they could do to make the feds happy, and the customer unhappy.

The LS1 is a beast. 315 HP is normally what they put down at the rear wheels. :eek: Don't even bother wasting your gas trying to beat one. It ain't gonna happen. Mid 13's on street tires is the norm.

BTW, boostedfury, please don't ever insult muscle cars by putting a '79 Camaro in the same category. ;)
