they could've put the engine in the moon rover first and it would still be a truck engine. even the ls family has distinctive truck heads and cams that never appeared in cars. lots of low end tq, low rpm ceiling and no past peak power is not a "high performance" car engine. it is historically a recipe found in truck and van stuff.

the term "truck motor" goes far beyond the lt and ls families. it extends to all makes that followed the same model for a truck engine. it's not news.

I'm not seeing how any of this is a bad thing or anything to criticize GM for. I'm not saying that you're criticizing GM. I'm saying that somehow the Ford trolls came here with what they thought was some bombshell info. I couldn't care less if the LT4 or LT1 is the exact same as a truck engine or if it literally is a truck engine. That thing is effing awesome and is arguably one of the best powerplants among modern vehicles and has the best bang for the buck and kept production costs to a minimum and powers vehicles that are utterly destroying anything Ford can come up with regardless of how many years, renditions, PP versions (PP1, PP2, PP2.5, PP7.12), CF wheels, or any other gimmicks they have. LOL!! Truck engine all the way!!

BTW, my truck engine in my ZL1 is being transported to the shop next week for the stage 4 package to be installed!! And when all is said and done I'll be looking to eat up some GT500s!!

Very interesting, I also noticed that the lap time of the Corvette C8 Z51 at LS per MT's Best driver's car performed by Randy Pobst is slower than the one previously posted by the 2017 Camaro SS1LE. That's amazing for the 6th gen Camaro
Corvette C8 Z51: 1:37.83
Camaro SS1LE: 1:37.77
Both of them on Summer street tires

The SS1LE can lap faster than the C8 Z51 but it wouldn't be faster than the also N.A. C7 Grand Sport.

Here I share you some great videos that I was able to find of a Shelby GT350 VS a 6th gen Camaro SS1LE.

Seems that on long straights the Shelby gets away but the Camaro SS1LE is always able to catch up on the curves.

This truck engine has

• Direct injection, 2000 psi fuel system
• Variable valve timing
• Domed 11.5:1 aluminum pistons with a scooped pre-chamber area to ”enhance initial combustion”.
• Forged connecting rods
• Forged steel crankshaft
• 6-cross-bolted main caps
• Oil-spray piston cooling
• Equal length exhaust manifold runners

It's advanced, economical and has a better powerband for street applications. Pony/Muscle/Track cars. Camaro dominates track

I'm always struck by Coyote / Voodoo reviews that extol their high rpm capability. They are weak at the bottom. Take the Coyote power curve, shift it to the left 1500 rpm and lay it over the LT1.

LT1 hits the rev limit sooner but is also alive sooner. You have to work to keep the Coyote in its powerband.

The LTI "available power is like a set kof double Ds (no matter where your face is... theyre everywhere)"

If the LS and LT are truck motors, so are the Mod and Coyotes. 2 valve, 3 valve, 4 valve, 4.6, 5.4 and 5.0 all appeared in trucks or SUVs. It wasn’t until recently did those engines rev any higher than their LS counterparts.

[s346k]

oh i agree the LT1 is the best na v8 available, hands down. i'm not crazy about DI and boosted motors as i am not a fan of gasoline or spraying meth.

i do a lot of chimping around on weekends with other cars. you guys can say what you want about the coyote motor being weak and soft down low. the cars still perform.

i can't honestly say the mach 1 was aimed directly at the 1LE. idk what they're doing with the car. it appears to be more of a vanity move than anything. it doesn't fit anywhere given the price:equipment.

The LT1 is a very good engine, obviously, with modern tech. The Gen 3 Coyote is also a very good engine and pretty strong across the midrange up to 7500 rpm. The power band is surprisingly wide - I'd say from 3500 to 7500 rpm. Especially 4k and above.

High rpm is a hallmark of exotic engines. Think Lamborghini, Ferrari, and up to the extreme like Indy cars, F1, etc. A Coyote approaching 7500 rpm sounds pretty great, and is fun to take up there. It was also kind of cool to know that at 5000 rpm I was only 2/3 of the way to redline.

The Gen 3 Coyote has much more midrange torque than earlier Coyotes. With the A10 and 3.55s it was quite fun.

It's a truck engine! It's a truck engine! It's a truck engine!

What does that even mean? How does that enter into any objective evaluation of a power plant? If it's got a great power band, with good power and torque, with a lot of tech, I wouldn't care if they put it in the Oscar Mayer hot dog vehicle.

I certainly enjoy revving out a motor to 7,500 rpm, but I still believe, from the old days, that revs for torque is no bargain on the street,

Absolutely nothing.

It's a very logical and realistic argument for those who were on the losing side and getting their tails kicked for years and having to pay more money for slower cars with less options that even when you upgrade by 2-3 tiers still could at best just barely beat the lower tiered competition.

The competition prefers engines that drink a quart of oil and catch on fire...anything as long as they think it isn't a "truck" engine.

Well most people with common sense agree with you. But we're not up against people with common sense. We're up against people who paid $5K-$15K extra for the GT350, got toasted by the SLE, paid $15K extra for a GT350R just to match the SLE, paid $10K+ extra for the GT500 and are getting beat by the ZL1, then paid who knows how much extra for the CF version just to still get their asses kicked by cheap, less powerful "truck" engines.

Imagine what GM could do if they made actual performance engines instead of "truck" engines.

That just needed repeating.
