Yeah, "advanced cams" isn't understandable for Americans. They're just now learning not to bury the cam in the engine. :p

I'll take an LS7 over any OHC engine any day. ;)

I'd take a DOHC 6.0 v12 with variable length intake and exhaust runners. :Q

I'd take a LS7...hey even a LS6 would do......Camaro or Chevelle .... :)

and be so damn heavy and huge that you can't fit it into most cars.

It's not heavy or huge. V engines are pretty compact.

DOHC heads are monstrous.

DOHC engines are a lot heavier than a pushrod engine.

then why does about 90% of the market use them?

their advantages must massively outweigh the disadvantages ;)

BS on the 90%. Ford F-150s make up a ton of the market and not a single one is DOHC. GM trucks do not use DOHC. dodge trucks aren't DOHC either. pretty sure all honda V6s are not DOHC.

ornery is right, you're good at making up BS

the accord's V6 and its derivatives (used in most of their vehicles in the US) don't use DOHC. i couldn't find information for ALL of their V6s in a short amount of time.

the ford and GM trucks combined for almost 2 million vehicles last year. dodge was probably another 500,000 or so.

Honda's J series (accord, odyssey, ridgeline, pilot, tl, rl) is SOHC. Makes comparable power to Nissan VQ with one less cam per cylinder head.

It's called volumetric efficiency, I wouldn't expect the pushrodders to understand.

sohc ,dohc has many advantages ..... wider powerband, higher rpm, better port layout, fuel and emissions efficent, and on and on and on.....

It's called volumetric efficiency, I wouldn't expect the pushrodders to understand.

I think one thing that "pushrodders" do understand is that there is no substitute for cubic inches...... turbos, blowers, nitrous, whatever works good on a 4 banger will work twice as good on a good ole pushrod V8......There is a simplistic beauty in the brutalness of a big block big cammed over carburated 1200 rpm idle rumbling V8 that some OHC'rs don't seem to understand..... although that Celica owner got a pretty good lesson...... ;)

I said the most powerful car engines in the world. Top fuel dragster engines.

There is much more to the puzzle than just VE. I wouldn't expect you to understand.

And BTW, the VE of my car's engine exceeds 100%. Go figure that one out.

What does volumetric efficiency have to do with where the camshaft is located?
