2009年8月11日 · I say pushrods. The Automotive press is saying pushrods. Heck, even the Europeans are lauding the supercharged LS9 and LS2. We cannot argue with that, expecially since the only alternatives are the V8 DOHC mills from Ferrari and Lamborghini that, while generate near-pushrod horsepower, are...

2024年7月25日 · The car is a staggering piece of machinery. And at center stage is the 5.5L LT7 twin-turbocharged DOHC V8. (And, yes, it’s still got a flat-plane crank.) This incredible engine makes 1,064 horsepower and 828 pound-feet of torque. It is based on the LT6 that is found in the engine bay of the C8 Z06.

2009年8月12日 · However, at this point the ohv V8 if given the same money as the most expensive dohc V8 would be competitive which is a relatively new possibility. "From tech stocks to high gas prices, Goldman Sachs has engineered every major market manipulation since the Great Depression — and they're about to do it again."

2013年1月28日 · But after 2008 and cancelation of ultra v8 i think there is little or no hope of seeing any engine bigger than v6 carrying DOHC/SOHC heads from GM. Click to expand... Here's the Brabham-Pontiac OHC Trans-Am engine (2 made)

The reason you don't see a bunch of large displacement DOHC V8s is for two reasons. First of all, there just aren't a lot of really large V8s left anymore anyway and secondly, four valves and a bunch of cams to operate them aren't really needed at those large displacements - GM keeps proving over and over again that you can flow plenty of …

The leaker has seen or worked on the Gen VI V8 DOHC heads but he doesn’t know GM’s plans for them. Could be destined for trucks but not the C8, or maybe they were developed but then cancelled along with the Blackwing V8TT when GM shifted focus to Ultium.

2007年10月1日 · While I don't like the idea of having DOHC on an engine that seems to be doing just fine with OHV and 2 valve per cylinder (and hasn't even used 3 valve pushrod heads or DI on any engine, let alone AFM or VVT on the Vette), the …

2015年3月9日 · The largest advantage to DOHC engines vs OHV on your typical value muscle car is the ability to have full Variable Camshaft Timing (VCT) on as many as 4 camshafts. Its cheaper, lighter, and has smaller packaging to use one camshaft on V8's like the '15 Camaro SS, but you will find better numbers on DOHC w/VCT on V8's like the '15 Mustang GT.

2019年7月16日 · This is corroborated by early intel that the C8 Corvette would eventually feature a DOHC V8, similar to Cadillac’s Blackwing V8. Seeing as Cadillac decided to preemptively cut the cord on its CT6-V super sedan , it makes sense, that instead of throwing away this all new powertrain package, that General Motors would naturally hang on to it for ...
