Intercooled GN's or EFI 5L 5 spd Notchback Mustang's, which were faster bone stock?

[olds307 and 403]

I can't believe, I am actually asking this. A guy on the Challenger forum actually said the 5L LX 5 spd ran 13's stock at the track and smoked GN's and TTA's at the track when new. Weren't the Mustang 14 second cars? My BIL test drove a used 87 GN and blew the doors off a 5L Mustang in the early 90's. Dwayne isn't a BSer. I remember my ex BIL spanking them in his 71 Chevelle with an iron head, cammed 327 sbc in 1989. Am I wrong or was the 5L Ford the destroyer of all things on the road?

I might have as well, who wants to be seen in one of those ugly boxes.

The Mustang's were faster than the Iroc's, but the Iroc's handled better. The Grand National's would beat either in the quarter mile. Had buddy's that had both LX's and Iroc's. As I recall, the Iroc's were mid 15's. The mustang's were low 15's high 14's. With a gear and offroad exhaust, they were low 14's, but still not close to the GN's.

A poorly tuned/maintained, incorrectly fuelled, and poorly driven Turbo Buick will get outrun by a Yugo.

The low compression V8s of 5.0s and TPI F-bodies are much less susceptible to the volatility of the Turbo V6.

Agree Mike, look at the original carbed versions of the 3.8 and 4.9 Pontiac, especially . The one shop I worked in a 87 GN came in a few times. My Boss mentioned the factory fuel pump was a big limiter and just changing it with a chip really woke up those cars up.

Nobody was spanking anybody. Stock to stock. Both cars were separated by less than half a second and a both ran high 90's to 100 in the quarter.

I had an 88 Mustang 5L 5 spd LX hatch. 3.08 gear with no other options. On a stock 225 60 15 tire, paper air filter it ran 13.9 @ 99. All the good ones ran high 13's or low 14's only when lacking driver mod or auto were they mid 14 to mid 15. Cheap and simple bolt ons made 11 to 13's a common number for Mustangs at the drag strips in the 90's.

GN were often not running right, common. Check engine lights, no boost etc but when they were working, high 13 to mid 14's was the norm.
The nice thing about a boosted engine is it's 1 mod away from running in the 12's. Boost and tires was high 12's. Nothing cheap after 12's but 11's was doable with a "stock appearing car"

Well apparently the Mustang was King of the Road. It looked like crap but went like hell. I always assumed they were mid 14 second cars, still fast for the late 80's.

still the fact that a two door Buick was faster than the vette of it's day was pretty good. must've hurt a few ego's of the vette guys in their circle @the local car show..

Buick was awarded with a shutdown of production of the line so the Vette would be back in prominence. Imagine a turbocharged V8 in a Regal 🤔


Regarding the Mustangs, turds when the Fox was released and still are unless you have $20-25K worth of Ford under the hood or a used LS. 😉
