Let's summarize the advantages of the pushrod V8's over the DOHC V8's:
  • less weight
  • much more compact
  • fewer moving parts
  • lower height
  • less cost
  • cheaper to build and repair
  • lower maintenance costs
  • better low end torque
  • better power density
  • equal or better efficiency
As for the so called "plastic" body panels, that has been well covered. They also don't dent from minor dings.

Exotic materials = exotic prices.

The Corvette formula has worked for decades with a few bumps granted.

I’m happy with it 😎👍

Corvette has already had a duel overhead cam engine, the LT5 designed by Lotus and sold back in 1990 as a C4 ZR1. Terribly expensive but fast for it's time. I saw one at a show with the original sticker on display and the ZR1 option was as much as the base car, about 30k. The engine was so complex neither Bowling Green nor any other GM plant could assemble it. Mercury Marine built it for GM, adding to the expense. Now couple a modern engine like that with a true carbon fiber body and we're talking about one expensive car, way beyond the purchase power of most of today's Corvette owners. But you'd have some bragging rights at the cars and coffee, for what ever that's worth.

Your post (and this one) are intentionally provocative. You weren't asking a "simple question" at all or you would not have used phrases like "Why do Vette's still have a push rod engine and bodies still plastic." That is being intentionally judgmental. Then you have the audacity to accuse others of being angry. You are not fooling anyone. You are not the innocent you are claiming to be. Your posts and your constant polling are designed specifically to cause arguments. That you deny this is shameful.

0 to 60 in 3.8 seconds and 29.5
mpg. Seems like pretty good technology to me.

The engine being discussed is the Ford Single Overhead Cam (SOHC) 427; it was developed back in the 60's to beat the Chrysler Hemi in NASCAR but was never allowed to race. Chrysler developed a dual overhead cam 426 Hemi, but the engine never ran and was dropped when NASCAR would not allow the Ford engine to be used. Ford stuffed the "Cammer" into some Mustangs for drag racing, and they were very successful, ultimately giving birth to the Funny Car. Connie Kalitta, and a few others ran the engine in Top Fuel with some success. It was also used in some Ford bodied Funny Cars. I think a few even made it into Fairlane production cars. Very rare engine. Here is a link to the history of the engine:

This photo answers it for me. The Ford motor is nice, I had one in an F-150, but as you can see, it's big and not going to fit under the low hood line of the Corvette.

About the body panels, would you rather they be made from steel? Maybe aluminum? Just curious what the OP would make them from?

Nice article about current cars with aluminum parts.

Seriously? Can you not say, "cost, cost, COST?" Also, for the money both manage to work well.

I"m curious, though, what would you prefer to "plastic," carbon fiber? Or...???

Sorry that you read into things and got defensive (and angry): "Why do Vette's still have a push rod engine and bodies still plastic. I did not mean that in a bad way, heck I have vettes too! . Maybe I should of asked why do they have push rod engines and made of plastic? (Better for you?) .My posts are to ask questions but you don't have to participate. Thanks!

Maybe a bad question but why don't more (not sure if anyone else) companies use the same "type of material"? If its lighter and cost effective like everyone says?

Jeez, this again?

Because of COST. PERIOD!

They spendt the money over the years developing it, and the only reasons to change the engine design is that they are running on the edge of emissions and fuel consumption limits.

A 4 OHC 4 valve engine is MUCH more efficient.

Aluminim or CF, bodies would cost a lot more. It would require dealers to spend a lot of money on the body shop to deal with the Aluminium or CF repairs. (ask Ford or Audi about Aluminum bodies.) But, Chevy is putting Al doors, hoods, tailgates on trucks so they have to invest in the bodyshop anyway...

So anyway, it's about cost, and ROI...

Speaking of alternative body material....
Stainless steel panels worked well on the Delorean but not really practical for Corvette because of weight.
Paint issues/dents/dings/stone chips practically eliminated. You just blend scratches/blemishes into the brushed finish with a scotch pad or steel wool. As long as you stick with the 1982 MT, nice sportscars. Handel great, but slow......................

I was surprised when I realized GM still uses spark plug wires,(although very short ones). My 2005 Dakota has no spark plug wires,...……...The coil packs plug directly into the spark plugs.
