If i didnt need a truck, i'd get a new mustang and charge it in a heartbeat.

Both are great engines in their own right, but comparing a 6.2 to a 5.0...
Why wouldnt they do at least a 5.3 in comparison

Yeah, not really a fair comparison.
the GT350 comes with a 5.2, but it's not a coyote, is it?

Essentially it's a coyote in a way gm engines in the ls family are the same.

They are comparing their popular performance motors. The coyote is a good motor but LS is tops in the last 10-15yrs

Plus that's what their stock cars come with

It really doesn't. Given the choice and an unlimited budget the Ford Modular will always make more power simply because the engine block design will hold up to it. Even with a Dart iron block the LS will give up long before an iron Mod motor does. A better test would have been using a 6.2L Hurricane instead of the Coyote, 500 hp N/A in factory trim before cams.

Tops as far as junkyard parts and cheapness to build, but the new ford motors blow past the LS as far as power. With this comparison you have an engine with almost a quarter more displacement barely edging it out. Hell a ford 5.2 here in this situation probably beats the ls3.
Like I said earlier both engines are great in their own right. It's funny this thread came up. For about the last 3-4 months Ive been torn on my next project. I am either building a 67-68 mustang with coyote or late 50 chevy truck with an ls. I am starting with the engine first and still can't pull the trigger. 5.0 with a bunch of shite or 6.0 stroker or lsa(might have a trade). I only have SUVs and trucks so part of me wants a car as well

I'm so intrigued by that voodoo 5.2.
Posted on 6/21/16 at 11:10 pm to NYCAuburn
How about 6.2 ford in the mustang. I know it would probably not fit, but you can find junkyard 6.2's pretty cheap. Would be pretty rare build and sweet. But like I said that might not be possible.

Very true. A few years back, 2013, hot rods engine masters allowed the ford dohc motors in provided they could reach the minimum 400 cubic inch mark. The end result was those motors dominated so bad that not only were they banned, but even John Kaase who won, supported the ban. His rationale was that a production car engine with aftermarket cams won that competition.
The pushrod gm motors are cheaper up to a point especially normally aspirated but forced induction is the domain of the ohc motors. To put it in perspective, John Mihovetz has run 5.9s in the 1/4 using a 4.6 with a production block, heads and crankshaft using twin 80mm turbos while the fastest LS uses aftermarket everything and twin 88mm yet still runs far slower mid high 6s.

All the nonsense metrics about pushrod motors being too high of displacement really doesn't matter in the real world. If you look at fuel economy and performance when compared to a dual cam motor they aren't very far apart. An example would be the 8.4L V10 from the Dodge Viper that makes loads of power and has comparable efficiency when compared to some of the other cars in the segment. People can flip their noses up about pushrod motors being "too archaic" but people will continue to use them for the simplicity and the flat torque curve that most produce.
And just to demonstrate actual size of LS motors, the LS V8 seriously blows out the competition for compactness. There is really no other V8 that can wedge into almost any engine bay. The damn thing is almost smaller than the 4 cylinder in the Miata.
And when you compare it to the Coyote, you see why more people do LS swaps than anything else. Well, besides the fact that the LS is pretty easy to find in any junkyard (an iron block version at least).
The heads on the Coyote severely limit where the motor can fit. For simplicity and compactness, the LS is very hard to beat.
Where you really see the LS motor perform is when you go the forced induction route. The Hennessey Venom GT uses an LSx motor to make over 1200hp and go over 260mph in under 2 miles from a dead stop. That is impressive.

The LS series is a great example of keeping shite simple. It's a good, cheap, durable engine.
Pushrod motors will always be around. They're just too cheap and compact to go away, especially now that we have electronic lifters.

Haven't heard of this. Got any pics? I'm curious now.

This is a pretty good article on valve train advancements.

Electronic lifters was evidently incorrect. One of my hotrod buddies had said that the new LS engines had electronic lifters which could be programmed to simulate a more aggressive cam profile with no hardware change. Can't find proof of programmable lifters anywhere. Maybe someone else can elaborate.
Diesels are what I do so I don't keep up with gasser advancement beyond development of direct injection fuel systems. I think as long as you see a need for an affordable torquey durable gasser, the pushrod valley cam V8 isn't going anywhere.

Love the Hennessey Venom GT. But let's not pretend that Ford doesn't or hasn't offered a bad arse tuner vehicle or two.

The impression I got was that you could vary the length of the lifter continuously to basically modify the cam's profile. Looks like they just have VVT via timing chain phasers though.
