Some friends and I have been debating and wondering who's car would be the fastest between my '84 Trans Am (305, A4, 3.23 Posi, WS6), one friend's '86 300ZX (N/A VG30, 5 sp, ??? open diff), and my other friend's '86 Mustang GT (302, T5, mystery axle).

We were wondering who would be the fastest in the quarter and who would have the advantage in the twisties. The Z has about 130k miles or so, the Mustang about 189k, and the T/A almost exactly 72k. The Mustang has straight pipes but it also has heavy *** subs in the back. Other two are bone stock.

Anyone have a guess?

idk in my head they seem like they would all be close. maybe the z31 would be at the top

I would say the Mustang, having more power than the other two. The Fairlady is quick, but it has on open diff, which won't help. I've driven my friend's turbo'd 300zx (stock) and it's pretty quick, but we did lose to a fox-body.

Will be a good race between all of you, you might win if both can't shift well.

Mustang in a straight line. Z in the curves.

You guys are giving the advantage to a 200k mile Mustang with E6 heads and what are probably 2.73 or 3.08 gears if it's still stock? Is the 305 a HO? or LG4? If the Firebird were an L69 HO, and IF the Mustang is bone stock, it'd probably be pretty close. The Mustang has a slight weight advantage, but 86 was speed density, junk heads, restrictive everything. 87's were faster with new heads, but the "fast" Mustangs were the early MAF cars, and the 93 Cobra. If the Mustang has been modified all bets are off.

Either way, If the 305 in question is a LG4, call in sick.

Unfortunately the car in question is an LG4, though I'm fairly sure the Mustang has the 2.73 rear end since he always brags about how he can lug the car along at around 1500 rpm at highway speeds and I'm pretty sure his limited slip is on its way out. The car also does seem to have a little hesitation in the gearbox and it's hard to put into third.

Would it be close enough to be about who ratchets/ bangs gears faster, or will this be embarassing? (if it is I won't hear the end of it until I can afford a swap)

Also, how much big of a difference between the cars would there be in the corners? Stereotypes would have me believe that the Z would blow the other two out of the water but the WS6 package feels pretty impressive... haven't pushed it too hard though because I need new tires. I have no clue how the Mustang would do either.

Corners, it will be a toss up between the Z and your T/A. My experience with the 300zx was only in straight aways, but it felt good handling the few turns I made but my camaro does feels better.

Mostly personal preference and experience for me...could be my friend's Z had horrible suspension/steering and needed a replacement. It was a lot easier, and quicker, to shift than my camaro.

Too many variables, lets just say it will be a nice tight race for all of you. And if you can, get footage of the racing!

An 86 Mustang 5.0 with a 5spd and 3.08 gears is fairly slow as 5.0 EFI Mustangs go, but that's still a mid-high 14 second car. On it's best day a LG4/5spd might crack into the 15's. It's a lot more likely you'll be touching 16's. The L69 is a huge upgrade, exhaust manifolds, y pipe, cat, catback, camshaft, compression ratio, it's all improved. The Mustang 302 also responds much better to modifications.

If you want to win, then just cheat... Nitrous, full exhaust, camshaft, gears, you can level the playing field.

The fox has got yall I think...

I plan on running them late this spring once I get her back out of storage and broken in again. I definitely will try and get some good footage of the drag and some of it going through the corners once I get some decent tires on it.


Between college and keeping the car going my wallet's pretty thin. I do plan on doing some of the free mods and possibly getting a Magnaflow cat-back since the junk factory exhaust has a gaping hole in it, but that's about all I can do in the near future.

Well I finally ran the Fox today... and I actually was able to hang on to him. We did a couple pulls from 30-35ish to around 75. The first time my transmission acted up a little so I got out of it, but the second time I stayed in it and actually started reeling him in at higher speeds. I was never behind more than a couple car lengths when I was on it.

Unfortunately, when the car went into third it shifted back down into second briefly and back into overdrive... it didn't feel like a slip but I'm not sure what it was... hopefully a fluid change will fix this and I'll do better next time around. But today definitely made me feel a lot better about my T/A and it's little boat anchor.

No offense but that's not really close or hanging with him....a few car lengths is a bit much.
