Need Help from Those Familiar With 5.0 Mustangs I'm not much of a street racer, so I ask these questions almost solely out of curiosity.
There's a guy around town who has a 79 Mustang who, as best I can tell, is pretty popular around the street racing circuit. I've never talked to the guy, but I've heard bits-and-pieces about his car and am a bit curious just how fast it could potentially be.
The engine is a 302 stroked to a 327. I have no clue what kind of heads or cam he's running. It lopes nicely, but not quite as hard as my T-ReX. I've been told by one of his friends that the car was built to handle a lot of nitrous. I have no clue How much he considers "a lot," though.
The car really doesn't look or sound like something incredibly fast, but I know that doesn't mean much. I've heard everything for "a modded bike only had him by half a car and he wasn't even spraying" to "he got beat by a 2100 lbs. Civic."
Assuming this was a nicely built car with quality (though not exotic) components and, say, a 200 shot, what kind of power would he be putting down?
Thanks,
Josh

Remeber a good Fbody should just top a 12.9 with less rwhp and a higher curb weight.

The 79's had just a 302, real weak, I think it was only like 170Hp stock. the HO 5.0 didn't see duty until '83. If he was smart, he built a strong motor off of a rollerblock 5.0 HO and dropped it in. I used a '92 ex-CHP motor and built it up with forged internals, it was a monster for only a bored 302. Higher comp ratio and better cam with an improved carb on it. I never ran N20 through it (I used the forged internals for that reason) but that thing was fast with some 3.73's in it. So be careful, I installed a stock dual exhaust system on the car (it had single originally) and was quiet as hell. Not a big lope either. I had to deal with emissions in CA. I would gather to say that is was faster than my 1994 Trans AM bone stock.

My fox feels faster than my old LT1 (I dont remember my old TA having trouble keeping the tires planted w/o squeeks when it shifted at 3500 rpm in 1-2-3 shifts. (it was A4 though, so I dunno.) Will be getting DR's soon, the 20'+ of rubber on the 1-2 shift costs time.

327s can put out anywhere frmo 300-375hp or in that area depending on how it is built. I'm running 13.2 on street tires with less power than that. His car is going to be alot lighter than mine so I would expect low12s or high 11s out of him with an average driver.
It really is hard to tell unless you race him.

I seen 12.5's and had 281rwhp in a full weight lx hatchback.
Lots of juice and a small stroker can see some amazing times. Look at the NMRA guys. Small blocks with juice running 8.20's and still streetable. nutty!

I have heard of high 12's with 265 rwhp as well. A 5.0 dead hooks, on a stock suspension with street tires, 1.8's and the like 60' times are the norm if the guy can drive (first to admit I PERSONALLY prolly could not as of yet claim that...)

Yah like how stanger88 said a 9 second 5.0 will sound like a 15 second 5.0. Just dont underestimate a 5.0. I built my 89 notch for less than 11 grand including the price of the car and i was doing 10.6's. BTW i have heard 11 second 5.0's way meaner sounding than myn. Stanger88 what do you do in the 1/4?

Very unsure as to my 1/4 ET's I know its better than 14.0 (beat an S2000 from a roll at 55-95 using only 4th gear 
) But other than that, I have no clue, car is in the shop being fixed after some aspiring Jeff Gordan ran into me while I was....parked at a gas pump filling up. Also they are fixing a drive-line vibe (very possibly going with FMS aluminum shaft), probably replacing my rear springs, power steering pump (been acting up) and I am hoping to get some DR's. All in all, on DR's I would hazard high 12's to low 13's. I know I raced an A4 LS1 Vert Z28, but he cheated, nailed it from 1.5 cars back, while I waited till he was = with me (already he was moving 10-15 mph faster) and then at 60 i went into 4th (works on S2Ks, not LS1's) and but 100 he had me by about 4-5 cars and we shut down. So from all of this, I have not a clue, you tell me, until i run it, yer guess is as good as mine.

your car sound like its mean also. race for fun and see what the outcome is
have you really looked at the car does the car have a bar in it 6 pt 10 pt etc.
sumped tank 1/2 in. lines mabe a 9in rear all that will give you a little insite but not much.
