I don't know very much about Nascar rules, so help me out with something I've been wondering for a while. Nascar engines are restricted to 358 cu. in. with pushrod motors and carburetors, right?
The Chevys are 350s, the Fords are 351Ws, so what are all those Toyolettes running? I'm unaware of a carbureted V8 pushrod Toyolette. We had a "Piston Power Show" in Cleveland last year and there was a Toyo Nascar car there. I asked the guy at the display the above question. He evaded it. He wouldn't open the hood either. I guess they have something to hide.

Do we know that for sure? It was originally scheduled for 2011, then pushed out to 2012.
Not questioning you, I just can't find something from NASCAR confirming that it is actually now used.
Cup went to fuel injection last year. Nationwide must not have yet, the motor on the wall yesterday was carbed but the carb was busted off the intake.

NASCAR Sprints Cup engines are 90 degree, pushrod V8s. That's pretty much the only way they resemble street engines. Thus, I don't think Chevrolet runs the proverbial 350 small block nor does Ford run a 351W. They all run pure, thoroughbred racing engines.
If you watched any races last year it was one the most conversed topics along with the use of E85 Fuel and the upcoming (this year) gen 6 car.
Actually watched 'em all. I tend to doze off during the blathering! I was interested in gen 6 'cause they said it might actually resemble the car. Also was sad to see Chrysler drop out.
The Dodge and Mustang at least are kinda like the real thing...rear drive, V8 altho special. Ya I know they all are NASCAR spec ....
Not to kill Santa Claus, but none of the chassis bear any semblance to anything that rolls out of any of the purported manufacturers' factories, either. Better to think of the 'manufacturer' as a title sponsor for the car, and not much else.

I think we have a winner.

I always thought they were running a 351's based off the clevland block.
used to watch it religouisly rarely missed a race for decades. Now imo too many rule changes, too many commercials nowadays, toyotas WTF and this chase to the race thing turned me off.
didnt even watch the 500 yesterday

I watched and was thrilled when three Toyota leaders blew up in the late laps. Toyota does have their own engine. AFAIK the Japanese gov backs Toy development.
Ummm, you might want to look up how much scratch Toyota spent on their F1 and CART efforts. NASCAR ain't exactly the ne plus ultra of technological development. Data acquisition and chassis engineering is everything, but the lump? Not so much.
That said, I've always enjoyed watching cars with Toyota nameplates nuke, IMSA Eagles excepted.
True, but it's not the same fuel injection system that we are familiar with on regular cars.
The fuel injection systems that come on all modern cars have a separate fuel injector for each cylinder. This allows each cylinder to get exactly the right amount of fuel/air each time.
Yet for reasons I can't explain, when NASCAR went to fuel injection last year they came up with their own system. These NASCAR engines still use a shared intake manifold for each side of the engine. So when we think EFI, we think of getting the right mix to each cylinder, but to NASCAR, EFI means that they get the right mix to each side of the engine. Then it's up to the engineers in the pit crews to determine how much the change the ratio of fuel between the inside-side of the engine and the outside-side of the engine.
To be honest, I can see moving to EFI since no one has carbs anymore. But to implement it in a manner that no one would design into a production car leaves me scratching my head wondering what the perceived benefit would be...
