Why are Vette's still push rod and plastic?
 

Ok you Vette head experts, why in 2019 do Vette's still have a push rod engine and bodies still plastic (or some variance of plastic)? Thanks

Because that's what works the best.

There's no requirement to start a new thread every day. :lol:

30mpg and no door dings while whuppin up on everyone.

I'd ask why the others aren't running SMC and rods!

LOL, never mind and you better get that snow blower ready! Comon man we running old outdated sh*t? PS- no requirement for you to comment...:thumbs:

Yeah, first real snowstorm of the season tomorrow. I got 3 shovels and 2 shitheads to help me clear the driveway. Counting the days to spring...…

Don't rag on old technology; they'll be making electric Corvettes soon enough......

no rust.
not as heavy.

Lamborghini still uses push rods....if it's good enough for them, I think it's good enough for Corvette.

Why mess with success!!

Not ragging, I just don't understand the technology, and why such mass vs OHC? .. Good luck with the snow, its 50 deg down here tonight..:thumbs:

:yesnod: :auto:

Are you using the pejorative term "plastic" just to piss people off, or what? The original Corvette used a fiber glass body, an innovation of its time. The current SMC is a much more modern variation. You should ask why other models "still use" metal and have not upgraded to synthetic material. SMC is the more modern material, so you've got that whole idea entirely backwards. Why a push-rod? Why not? What's so great about a DOHC engine? It's much more complex and tends to whine like a ricer. The push rod is simple, has tons of torque, and holds its own with everything else, as the specs easily prove. Mine gets 27.5 mpg, so it has nothing to apologize for. Surely you know these basics already. The real question is, what value is there in starting an argument?

Lots of moving parts in an OHC engine, and more isn't better.

Why change What Sells...So Their

Actually, this gets discussed some around the rule making for various endurance racing series (ACO, organizers of 24 hours of Le Mans, and FIA and the US sports car authorities).

A pushrod V8 weighs less than a 4 cam DOHC v8 of similar displacement. Adding to the advantage, the weight in a pushrod V8 is lower, which makes the CG of the entire car lower. As long as you figure out how to make enough power, a pushrod V8 actually has those advantages over some of the more 'exotic' 4 cam engines that they are up against.

DOHC DFI engines suffer from intake valve coking. Push rod DFI engines don't.

My Mustang buddy says same thing. I tell him because it still kicks a Ford motors ass. The GM OHV still beat the Ford DOHC engine for top speed and is rock solid. Rumor has it C8 will be a OHC motor. NASCAR package is still a OHV motor and seems to perform just fine.

Unlike many here, who are bitter old men who like to argue, NO., I was asking a simple question.- I own 3 vettes. Im not sure what the material is. Guess your one of the bitter, angry people who look for arguments..Sorry dog! :thumbs:
