I Guess I drive a deisel and I have 450 ft pounds of torque. Anyway I can't win on an ls1 site.

Why don't you dyno your car for the sake of this thread? Not trying to give you a hard time, but 260rwhp with just an E-cam would be amazing.

True I agree. i have been on some calculators [example] stang source and thats what it comes out to. But its not exactly accurate .

Let the LS1 guys feel the way they do, there are so many ragged out 5.0Ls in this world the chances of any of these guys running into a good running well driven stock one are pretty nil. So if you take that into account there arguement is correct.

That includes the fox staying emissions legal, full accessories stock weight, stock bottom end and off the shelf HCI--assuming 280-290rwhp for the fox.
I guess it depends on what you believe. In my world a 280 rwhp Fox is going to destroy any stockish LS1. You dont need any suspension mods on a Fox body to run easy 1.6 60'. Ive never seen a stock suspended LS1 get down in that range, Im aware that guys do it, but the level of commitment far exceeds that required for the Mustang. In any case why do you have all these variables, like gear and emission legality tires etc. etc. Im sure any 5.0L guy will go mod to mod with any LS1 guy anyday.

Ive been there, I run pretty decent in my LS1, 12.92@109 with the RSAs with Catback and Lid only is pretty good in my book. Ive got plenty of friends that run mild H/C/I 5.0Ls into the low 12s to know what happens when you try and race them. From a roll its a different story, because at 330 rwhp I still out-power them, but its hard to get over a 1.6 60' vs my 2.1 and act of god 2.09 in a straight drag race.

My whole point was not 1/4 mile time anyway. I just mentioned that a stock well driven good running LS1 and a likewise 5.0L are a good run stoplight to stoplight or 1/8 mile or less.

I agree with pretty much everything you said. If you are talking showroom stock though, I still don't think even stoplight to stoplight they are a good match. Your buddies might pull 1.6's, but a showroom stock 5.0 on stock tires is not going to be doing that. Stock for stock they aren't even close.

The "E" cam on an otherwise STOCK 5.0 is goign to be worth 10-15 rwhp. The E7 heads (stock), while some people have used them UNPORTED to run 10's, they were packing BOOST! are a BIG hold-back on an NA fox. GT40P's by themself are worth 25 rwhp, couple that with a good cam/proper valvetrain and you are looking at a 40 rwhp boost for a head/cam swap that runs about $800 for the whole shebang. YEs, an LS1 gets A LOT MORE out of it, no argument, but $800 for 40 rwhp aint bad, if you go with AFR's you can get 70+ out of it. But yeah, E-cam + stock 5.0 5M= 205-220 rwhp depending on where you started as stated before

Stanger 88 what kind of power should a 5.0 make with e-cam ,longtube headers, h-pipe w/ no cats ,pro-m 75mm mass air sensor 65mm tb adj fuel reg ,and of course and cold air pipe make? Just asking.

I know you weren't asking me, but probably closer to 220rwhp. Most guys with the ported E7's/intake and a better cam than the E don't even make 260rwhp.

Is that with stock tires?

The variables are to keep some type standard to base a comparison off of. I have no doubt that when you run longturbes, shortbelt, H/C/I, -200lbs weight, 4.10gear and stickies etc. that a 5.0 should kill a stockish fbody.

I'm sure their cars are a little more setup for good 60's. Did you have a gear or sticky tires? Did they?

Considering the 0-60 times...I think it should be a decent amount of space.

Again....heres the specs: CAI, 90 model AOD car, all stock except the CAI and pulley's, ran 9.08. I have seen lots of Vettes, and lots of F bodies that didnt run that good. So, i know they cant rape my car on a 0-60 run. I KNOW i dont have a car that runs that much incredibly better than any one elses, so why is it that I can keep up with a vast Majority of F-bods? Not much to driving my shitty auto, it wont hardly spin, so thats no worry. I think its kinda funny to go to the track and pick on f bodies and such, they always expect to see something under the hood, then they see all the stock crud from 1990. I know 9.0s isnt a rocket, but its a good argument for the 0-60 run.....mine must be comparable to some decent LS1s.

Good luck going around picking on LS1's with your "stock" auto 5.0.

My 5.0 hung with many LT and even some LS1's easy until after the 1/8 mile. As soon as we crossed that point it was like they hit the throttle and were gone. 5.0s are very torque happy monsters down low. But once you hit 3rd its like hitting a brick wall. F bodies just pull no matter what gear your in.

i'm sorry but i've have yet been beat by a 5.0. The closest was a trickflow heads and cam full exhaust 3.73 geared one at the track. He was even running drag radials and i have street tires. I only beat him by a car. My mods are 4.10 gears, centerforce clutch lid thats from a 98 z28. I've also roll raced a cammed and full exhaust geared 5.0 that wasn't even close at all. not saying a 5.0 can't hand me my ***, i'm just saying i dont believe a stock on would come close.

All this 1/8 mile stuff is really getting to me. I really wish I could find some of my old timeslips from my mustang. Here was my best run in my LT1

60` 2.221
330 6.012
1/8 9.031
1/4 13.814
MPH 102.95

Now this is all out of memory but is not completely accurate. This was the best run in my mustang.

60` 1.98
1/8 8.8
1/4 14.4
MPH 92.4

My mustang would have killed my LT1 to the 1/8 mile. But like I posted before, after that the LT1 would have passed me like I was standing still. 1/8 mile racing and 1/4 miles racing are far from the same. The 5.0 is a good car, I am not trying to put them down. But it takes a lot of work and a lot of money to make one run with a lightly modified F body.



And another thing, this talk about an E cam making 260 RWHP on a stock headed car is bullshit. Estimating HP and getting real numbers are two different things entirely. A friends 5.0 with the B cam, Cobra intake, GT40 heads, LT's no cats, dumps and all the other bolt ons that are a regular with foxbodies made 250~ HP. **** my friends 331 stroker only made 396 on the engine dyno. And that is a professionally built motor.

Well since you brought it up again I said that I figured thats what it had so before you go talking sbullshit you should get your facts straight. And I also admitted that it was my estimation ok. With out the cam on bullshit tires my coupe went 13.83 w/1.89 60ft guess thats bullshit to hugh ? And as far as costing a bunch of money to get a fox to run with an f body you can't be serious cause mine already does. E-cam 150.00 pro-m 125.00 used h-pipe100.00 long tubes 300 gear373 125.00 WHOOPING AN LT1 OR LS1 PRICELESS !!!!! Beforeyou gm guys get to mad own a camaro also

I wouldn't say whooping an LS1 would be priceless....I might say unbelievable! Sorry to poke fun at your LS1 slayer Just the thought of a 215rwhp E-cammed auto 5.0 driving around picking on and whooping LS1's sounds funny, LOL!.
