I bought into the 5.0 hype when they first came out. after seeing then run at the local track and a few encounters on the street I wasn't as impressed. I had a 114ish bolt on ls1 car. I never saw a stock 5.0 trap over 112 at the track here. even with good drivers. but with that being said; for every underperforming 5.0 I saw the were 8 ls1 cars performing terribly, as well.

I still think the 5.0 is a more capable car mod for mod. both cars given a competent driver and modifier will show the 5 liter victorious every time.

I've seen too many tune only 5.0s running lower 12s and trapping over 115 mph to discredit them. Stock is whatever, who the *** runs around in a stock car thats actually going to run ya anyway. I managed a 12.22 at 114 with gears, tune, lid, street tires, long tubes, etc...but knowing it took a 1.89 60' and perfect DA to do it when a tune only 5.0 can out trap that by 1-3 mph and run the same ET on a worse 60'...yea. Thats why I kept modding. The 5.0s are a better performer mod for mod, but the LSX still holds the title for potential imo. NOT LS1, but LSX...as in we can still ditch the ls1 and swap in all kinds of LS3, turbocharged LQ4/9 ****.

I will never get this arguement... guys the ls1 4th gens ended in 2002.. this is a new engine a new platform. One side can say yes the 5.0 is better than the 4th gens... I would expect it to be after how many years of difference... but Does the 2014 outperform the new lt1 because thats what you should be comparing it to. The 4th gens had their time let the 5.0 have it's time.

Too much ego for that to happen.

Notch's car would've did that fairly easily. Finished off I'm thinking ~120

Did you bud that went 116 ever go back to back it up?


I can tell you guys why the biggest difference in et between these to cars....mph to really. The 7.5 vs the 8.8. The old 4th gen is not gonna 60' with the Mustang while on the 7.5. If gm would've put a real rear in the car their minor mod/ bolt-on times would be much closer.

With that said the 5.0 should be the faster car overall.......it is 13 years newer than a ls1.

No but he raced my buddies white GT/CS that just went 11.8 at 117 4 passes in a row last weekend in 1500 da. Also the beginning race in that comparison video, the GT started in third gear and the CS started in second (same gearing)


And if 3.31s were the faster gear... i wouldnt have went from 3.73s to 3.90s. And I disagree with the rear end statement... yes with a drag radial, it will help.. but not on a street tire. I dont think a single one of my friends in any 5.0 has cracked a 2.0 60 ft on the stock 235 pirellis. But the lowest trap i have seen from any of these cars, is 110mph, still with that same 2.0 60 ft. That GT/cs averaged 13.0-13.2 at 110-112 when it was bone stock. And thats the heaviest model you can get short of a glass roof.

not necessarily. I was under the impression that the 3:31 cars ran the best. combine 3:73's with the really low trans ratio and there is a point where it's too low. like putting 5:13's in a stock fbody I bet it would be slower in the 1\4 than the 3:42's.

this. that's always been their advantage. however this doesn't work out nearly as well on the street and you have guys with light bolt on ls1's beating 5.0's because the 5.0 just can't get it's 1.6 60' on the street.

Yea big....they never want to take that into consideration.

Evan.....those numbers you posted are right in line with a free mod only 4th gen. ~13.0

Guys were posting dr times. Your just no gonna get maximum et out of a m6 with the 10bolt.

Hio, if you had a new 5.0 what do you think you could get it to run with full bolt ons and your weight reduction with all the tricks?

Well into the 10's. Probably about the same as the ls6 would do with a good rear( from the way it looks the 5.0 would need a trans). I consider the 5.0 and the ls6 a good match up with a slight edge to the 5.0.

But as far as lightly modded street racing the 5.0 vs ls1 there is no denying that a proper ls1 can put up a good fight with one. I've seen one 5.0 make it to the 11's at my local track......not a difficult feat for either. To get a 5.0 past a 11.5 is no easy feat apparently.....as it's no easy feat for a ls1.

Hio no trans swap needed for the auto. The manual well ya it sucks. But some guys have had luck going 9-10's in them.

Autos the 3.31 is indeed the best gear for the 5.0. Manual it seems a 3.90 is best for everyday cars. For drag guys the shops are doing 4.30's and 4.56's.

No one is comparing mod for mod here.

Wouldnt need a transmission... mines apart right now. A few little tweaks and its no weaker then any worked Tremec. Im glad i pulled mine apart. I may however build a second tranmission on the side (faceplated etc).


I also just swapped the clutch. Stock boss 302 "mcleod twin disk" was nothing but a valeo single disk made in turkey. Id love to find the person who started that stupid rumor. Either way... it has a REAL Mcleod twin disk in it now and it was 13lbs lighter then the stock assembly. Installing bronze shift pads (to replace my broken plastic ones) and new synchros(updated ford version, kevlar lined) in the trans right now. Forks are beefy and wont require any replacements...gears are huge. Cant wait to drive this thing again!
