Oh I was talking about in a purely performance setting.

It is the same formula my liter bike used. Make great hp at the sacrifice or torque. Make the HP high in an rpm range. And gear the hell out of it.

I never once thought man I miss torque on the bike.

Bring on the 2011 v 2011 comparisons.

We still haven't seen production 5.0s and 3.7s.

Its a 250lb weight advantage (less if the GT is optioned out). No need to be rounding up

Not in this generation.......

Isn't the fastest ever stock 5th gen time a 12.6? 12.7@111.3 w/ all the extra weight in there. Stock for stock you guys are going to have a drivers race, but the edge will be to the mustang. Every equal comparison shows that. Now modded, we will just have to wait and see.

Whoever was talking about BMEP, good luck making 200 PSI reliably on a pushrod, daily driven engine without a LOOOOOT of money. On top of that, while BMEP is a good indicator, it only works for average torque and IC engines' torque fluctuates massively, with certain strokes even reversing torque values completely in single cylinder engines. Although that doesn't apply all that much here, you get the idea. BMEP is a useful tool, but not an end all. That being said, we won't know how the 5.0 responds to modifications until it is out. Results will depend on plenty of factors that we really can't know for sure yet. It's all speculation at this point.

Fastest time is a 12.5.

Nascar motors are 220 psi and they are pushrod. Top fuel and funny cars use pushrod. The pushrod design is actually a newer design than ohc design.

Most all of the fastest cars in the world (6 seconds and below) use two valves per cylinder activated by pushrods from a centrally-placed camshaft.

We wont have to wait and see modded. It is who ever has the most money. If you are staying NA the advantage will be to the LS3. No way the 5.0 will make as much power as a 6.2 modded NA. Forced induction and or nitrous...may be the 5.0 from its strong internals.

Actually ULTA the stock internals in the 5.0 are about hand and hand with the stock internals in the LS3.

Both have the hyper-exploditis pistons. Although that is an easy fix for both motors.

The great thing is they both should be going through a complete change at the same time.

I know GM is going to get lighter and for Ford it is a stated goal. Ford just has a little bit of a head start.

I thought the 5.0 had a stronger crank and possibly rods? Havent checked lately... But I guess that doesnt matter if the pistons go first.

Honestly I am not sure on the crank. Although I do know those modular cranks are some strong bastards. I am not sure of the strength of the LSx cranks now days.

And I think the rods are both very comparable to. But yea it doesn't matter when the piston/s go.

If both are truly blank-slate redesigns (which I know the Camaro will be)...no one really has an upper hand over the other. THAT's what makes it interesting for me....historically, both companies have approached the same problems differently to varying degrees of success...this will be a perfectly-timed example.

[Sax1031]

The 5.0 is definitely not going to be a n/a motor. The LS3 is a monster and a half with bolt-ons and head/cam combos. Absolutely amazing.

No replacement for displacement and all that jazz.

The 5.0 should shine in FI applications though.

And how much is it if the SS is optioned out?

I can't wait.

Even with the stupid-high CR? The LS7 has trouble with that 11:1....
