Yep. Ford had to go forged years ago on the 03-04 cobra......at a measily by todays standard 390 hp to keep that thing together. That tells me on the normal 4.6 piston they were having problems keeping it together in testing. Only stands right to figure the threshold is lower for piston material holding up is lower in that engine.....whatever those variables may be.

Funny you should say that considering how many LS engines have spun their bearings. When you lean on an engine, there is always the chance that something is going to fail...no matter the brand.
I like bigger bore engines, but I have never heard or even thought of load distribution as a reason.

Not saying the zl1 is stronger around the track. But i would like to see a legit comparison that isnt biased towards either car. 2 cars, one real driver. It also has been proven the boss is the drivers car or the 2. If you dont literally know how to race a car around a track, you cant race it around a track.

I dont feel like writing a couple pages about structural considerations on piston designs, but at a high level all things being equal it would be easier to build a stronger piston in a smaller bore.

Those forged internals were needed to keep that pos 4.6 together. Did'nt seem to help the rods bearings staying in it. Once you get to looking there is a whole pile of spun bearings in those things.
I would take my chances with the bigger piston(6.2) distributing the load over a bigger area over the smaller more stressed piston(5.8).

agreed.... hence why the 5.3s and 4.8s do so much better in stock form then the bigger motors under boost.

I didn't call a 03-04 motor a pos. I called 4.6's a pos. Clearly the 03/04 motor is upgrade, but still not that great.

The Laguna comes with competition tires, a beefier rear sway and diff rear springs. The rest is literally all cosmetic. In theory the Laguna is the stronger of the 2 yet somehow it was 2 seconds slower. Ill tell you why... and people will flame for it because its against the zl1 but it happens all the time. Its just another comparison paid for by chevy. Ford does it, chevy does it, bmw does it.. etc etc. The car randomly lost 2 seconds to put the zl1 on the winning side of the comparison.

Also, GM has to be careful because we all know the LS1 camaros 65% of the time RAPED stock LS1 vette in the f-body years, to me this is why they discontinued them. why would I spend 50+k on a car thats Slower than my 17+k car, and it had back seats for groseries and golf clubs LOLOL
I worked at a race track for 9 years, most stock vettes could Barley go in the 8's 1/8 mile, and Most f-bodies would go 8.9-8.80's stock.
Just saying

LOL, I meant high level in terms of explaining what goes in to piston design, not power level.

Your right it cant do that with simple bolt ons... however, my bottom end can handle well over that power from the factory if i so choose to boost it, which i in fact may be very well doing this winter. And even still... 615whp on a cast bottom end may be do-able... but i wouldnt be comfortable with it. Ive personally seen how easy cast can fall apart with the slightest hint of detonation.

for those who dont think motor trend or car and driver ever get paid off to put a car on top, you fooling yourselves. It happens all the time. Not just chevy or ford. Its done ALL THE TIME. They are known for this actually. Why the hell would the boss slow down a full 2 seconds during this certain comparison? But this is LS1tech... so people of course will take the zl1 to the grave with them.
The ZL1 is the best car ever.. happy? I wish i had one... shouldnt have bought my car. CHEVY CHEVY CHEVY CHEEEEEVYYYYYYYY!!!!! Im done with this thread.. Peace out hommies!

I remember this specifically since i was actually looking forward to seeing how the 2 cars would compare on the track. The single test of the boss by itself, they loved it. They even stated it was a drivers car and you need to know how to throw a car into a turn and trust it and thats why it was so well approved of. Then in the test against the ZL1, all of this traits were twisted to now be a negative. I remember being pissed off because it was an absolute Boss bash session instead of a legit comparison of the 2 cars. At one point they said how much better the ZL1 was because the suspension could be adjusted via dash board electronically and the boss you had to get out of the car and adjust the suspension at the actual shock tower (like a normal track car).
I just laughed because somehow a boss with pirelli p zero garbo tires can lap the course faster then the same car with factory competition tires. Please.
The article reminds me much more of a presidential election. They focus more on bashing the other car then talking about the preferred car
Im not saying the Boss is faster around a track then the ZL1. Im just saying that there comparison test was a joke and biased. I want to see legitimate tests and comparisons. I want to see the ZL1 be the faster car because IT IS the faster car, not because someone just wants it to be. Get my point?

i would have to dig up both articles or if anyone is interest/cares... they can look for them. The original testing of the boss lapped the test course faster then the laguna Seca did in the comparison test. It also had a higher top speed, and higher lateral G. I cant remember if it was the motor trend or the car and driver tests.
