Default 5.0 Mustang??

Ok, so Im driving down the road and I see this loud mustang 5.0. Then I realize its an old friend from highschool and I heard he had a pretty nice new car. So I decide to play a little bit. Well, I beat him twice, nothing but little runs, like 30-85, but i beat him both times, by a couple cars. So we pull over in a parking lot and start talking. First thing he says to me is, and I quote, "I walk these things all the time." I kinda chuckled but didnt want to seem like an *** so I just asked him what he had done, how much he was putting down to the wheels, etc. He told me he was putting down 280rwhp, and that he could run "13 sec. sideways." Meaning, I guess that he has no traction and can still pull a 13 sec. quarter. He has a 302 which has been stroked to 331. a 234/234 cam, ported heads, and some other bolt-ons. Now I am almost positive that, veen if he did catch traction, I would beat him from a dig, but he was EXTREAMLY cocky,and I just let him be that way. Well I dont think a 280rwhp mustang could beat a 360rwhp ls1, or whatever amount of exact power im running. What do you all think. From the little runs we had, I wasnt impressed at all. Oh yeah...the last thing he said to me was, and I quote once again, "Dont let me catch you on a dry day." The ground wasnt really that wet anyway, it showered a bit earlier in the day and was about 56 degrees all day. What do you all think of this guy and his car. Could he beat me if he could hook? Sorry for the long story but I dont like when people run thier mouth and I think they are full of ****.

depending on what kind of mustang it is, it could have a 2900 (or less) race weight. A 280rwhp with traction (SLICKS) SHOULD run easy mid 12's.

In all honesty (and I HIGHLY doubt you are making 360rwhp, probably more like 340rwhp), that would be an EXTREMELY CLOSE RACE.

If he is making only 280hp and you are making 360hp then you should win hands down. Something doesn't sound right about his set up. A 331 should be making a lot more power than he told you it was making. He said he had ported heads. If these are stock heads that were ported they will not support much horsepower. The stock 5.0 heads had terrible flowing heads even with porting. Looks like he mismatched a large cam with poor flowing heads, this would explain the low hp. If you beat him from a roll and he complained about poor traction, then I would expect you to beat him from a stop.

Well it's a moot point, even if you are making close to 360rwhp, it's STILL going to be an extremely close race. The 280rwhp stang has EASY (I emphasize) mid 12's.

Unless it is a fox body coupe you have to do a lot of stripping to get a stang that light.

no...lol

depending on weight...and what do you mean by full bolt ons? I don't see you making that much power with just header exhaust and a lid.

Just didn't want him to think that it is easy for mustangs in general to be that light. The coupe with a 5.0 is the rarest one on the road, most are going to be an lx or gt hatchback which are in the 3400lb weight class. Or if it is a 94 or up it is closer to 3500 lbs, my 95 conv weighed almost 3800.

Sounds like BS to me. Not that it is impossible, but highly unlikely. Now I really wouldn't believe anything that he told you.

My 91 hatch weighed 3310 with me in it, when I weighed 165#'s, and my 86 notch weighed 3140 with me in it (same weight), BOTH full weight(and both with pony rims).


With your setup you are most likely closer to 340rwhp, just look around on this site and you shall see

Sorry, I was wrong on my weight numbers, my last mustang was a sn95 and the numbers you gave are correct for the fox bodies.

Something tells me he's not telling you everything he has....Its just not real often that you find a 331 with stock E7 heads (even ported)....Whats the compression? Its not "that" hard to believe that he has a kit on a car with a built motor....

Just some thoughts

that 2600 seems off. Is that with him in it or not? I run a full interior, but all LX stuff which is very light, no a/c, no smog, and alot of little wieght reduc here and there, and my weight is in my sig (including me at around 170).

His car should be fast, but I wouldnt be too afraid of it if I was you.

BTW, does anyone else think those are crappy numbers for a 331? I hope he doesnt still have e7's on it. I dont know who would do that.

My 1988 5.0 GT with all the heavy duty crap in it weighed in at 3240 with 11 gallons of gas according to D.O.T certified scales. I have around 280rwhp and I really am nowhere near mid 12's, prolly low 13's to be honest is what I am guessing I run. As far as the other guy, if his heads are ported E7's, no wonder he doesnt make more. He needs some heads on that combo.

Looking at your mods, with some good tires, you should have no problem gettin a 12 second pass my man....Just my opinion of course, but I don't think it'd be too hard
