(QUOTE) You really have no clue what amazing things gm is accomplishing with the pushrod v8 do you? (A) Yes I do, I was born in 1961, I think I came before the V8.
(QUOTE) With overhead cam engine you have to rev them out to get any performance at all. (A)This makes absolutely no sense whatsoever, it's the same thing as a cam in block. The cam HAS to turn in conjunction with the crankshaft. The placement and the amount of cams is different, the drive is the same. Just a bit more expensive.
(Quote)Go buy a BMW or get educated...
(A) Not only foreign cars have OHC I'm, sure there are a few floating around GM, FORD, DODGE already. I need to get educated???? 1 of you is 24 and the other is 26, I was taking apart gas and diesel engines when you were still a lump in your dad's pants.
Ok maybe not a dinosaur, I was born before the V8 so I may be considered a dinosaur LOL.
The pushrod is a weak link, the lifters are a weak link and the valve train instability probably cause more total engine failures than probably any other failure. The OHC engine lends itself to better valve train stability and higher performance, higher revving engines. OHC design is a bit more expensive. But you spend money anyway to make your engines more powerful.
What about the possibility of doing away with spark plugs. Nothing at all was commented on that.
People feel the same about carburetors and fuel injection. Some embrace different technology some don't.
