![]() Why is the LS so GOOD?? - /ENGINEERED
![]() Why is the LS so GOOD?? That’s the title of one of this week’s /DRIVE episodes. As you can see, the video below is all about the engineering behind the LS, and what really makes it one of the best platforms you could ever want for your project car. It doesn’t matter if it’s in a Corvette, a street truck, a classic muscle car, a supercar, or an off-road desert racer, the LS is simply one of the best engine packages out there.
It features a Corvette C6, a high speed bowl, and tire smoke. You’re welcome. BECAUSE DRIFT VETTE - LSx Drifting Showdown

![]() BUT there are reports of certain new vettes having engine problems, valve guides to the point of the keepers giving up, and piston pounding valve right through the cyl head...of course trashing the entire engine.....
seems odd to me, and GM is balking at what they SAY is a design problem.... ![]() ![]()

![]() As I see it, how many LS motors had that problem compared to the amount of these motors that were produced and are still going strong.
From what I noticed recently with the internet anyone who had an engine problem (in any car) starts a campaign on line that blows things out of proportion. I do remember in the mid 60s lots of guys bought big cube cars and drag raced them and when there was a problem the went back to the dealer for warranty repairs. I believe that is why GM got out of the muscle car business at that time. ![]() |

GM went to an outfit in Newport News Va. known as Bendix in the R&D daze, they gave Bendix some Olds 350 engines and some Caddy 425 engines and a few 500 ci Caddy engines.....The advent of analogue chips, called OP Amps short for OPerational Amplifiers meant high amounts of gain in a very small chip, made all sorts of signal processing possible, so they invented the first electronically controlled FI systems, and the injectors were batch fired as I recall......Bendix got bought out by Allied Signal, which is now part of Siemens ......the first systems got to production in '76 in the Caddy Seville.....and I tore a system out of a '79 Caddy Sedan DeVille, and modified it up on a Pontiac intake manifold, installed on my 462/455 Pontiac .30 over in my '70 Lemans/GTO convertible, I bumped the mpg by over 4 mpg with that one swap, as well as it ran SO much smoother....I did this over the winter 91-92 and it got published in High Perf. Pontiac mag Feb '95.......called Injected Madness....by the 80's they switched to digital computers, instead of analogue, cheaper to make by far, smaller too.... ![]() |

![]() Sorry, GM dropped out of racing and Ford and Mopar stayed in drag racing in the mid to late 60s it had nothing to do with EPA in those days. GM could not or not want to compete with Ford and Mopar cars.

![]() The LS engines are for sale in GM's Performance Parts Catalog (GM PPC). Just astounding horsepower out of relatively light engines. The supercharged 650 hp engine is available...and it's really an aluminum small block! Furthermore the GM PPC engines are smog compliant in all states, including California, if you install them in a car made before 1995. It really gets better. I've you're in a state that doesn't enforce smog rules, the GM PPC engines can be reflashed to produce significantly more HP!

![]() BUT true, the HEMI ruled the roost pretty good, Garlitz/etc.....I left the drag strip basically in '68.......went to one runoff here in Gainsville a few years ago, had earplugs and shooting muffs, One top fuel guy taking off, fun, but LOUD.....but when TWO of them took off in a race, the sound pulses were not in synch, to became additive/subtractive with the engines being out of phase with each other.....the air pressures were shocking to say the least....felt like getting hit on the chest with a ball bat..... I don't recall THAT kind of reaction back in the 60's..... ![]() |
