People seem to forget that not only is the overall weight substantially more, but when you are going in and then coming off a corner, you have a 65-70 lb crank that needs to be slowed down and then sped back up vs. a SBC 40-45 lb crank...Why do you think that Oswego and ISMA won't allow small blocks to run in the Supermodifieds against the BBC's...

Yep. It could be done with lightweight parts but it would no longer be an "inexpensive" option.

dont know what kinda times small block mods run there,...pretty sure thay have run there before,..the dirt track at lowes don't run regular events,..just special's,... the big block mods are lot deffernt than regular mods,driver sets in middle with wedge body like bords on both sides of driver.........no body ever said racing was easy,electronics can be teched just as any thing else,NHRA an NASCAR an F1 already are doing it...and it is the future,..sooner or later it will be come the norm.....

Doesn't NHRA use mechanical fuel injection for big classes, don't follow close.

NASCAR made the move to cripple start as parks, and it hurt many of them greatly, not for performance or economy, the cost was huge and is one more cater to large teams deal.

F1 has unlimited budgets and full carbon fiber chassis, are those headed to DLM racing? They even had cars they could adjust from the pits while its on the track. Best part is still use a wooden skid pan under them.

I don't see it happening at small local tracks anytime soon because of cost and difficulty teching it. There's no upside to efi, carburetors are easy to tech and use. Leave the FI headaches and phart mufflers to the ricers.

some of that is true,...but un opend minds are as good as blind...theres better power to be made with fuel injection,...an durability...ant we trying to go faster??? or just fast nuff to be in the running???

One news article I looked up had the parts for NASCAR fuel injection at $25,000 and the software to run it and tune $70,000.

So add over 90,000 to your operating budget. A great carb produces a ton or power for only $1500.

And most people don't realize it but carbs make more power at this point.

Actually neither of these statements are true. A few of the mags did comparisons and a properly adjusted and maintained carb in a racing application will out power and has better emissions than a FI setup when it is running at 100%. The EFI has an advantage only in it's adaptability for different driving conditions. As far as power the engine lost peak and lower end power when the FI was optimized than using a carb.

It's impossible to win a big time dirt late model race now a days without running a big block !! I don't mean a 4.5 bore spacing I mean an actual big block !! All of the top guys run them !!! Why do you think Owens , oneil , bloomer and lannigan are soo good ? It's because they run 600 plus CI big blocks !! And they turn them 13k !!

If there is anybody believes that I have some ocean front property in Arizona I need to sell them.

I'm reasonably certain that hucktyson was being tongue in cheek with his post!! Or at least I hope so!! LOL

...the best tuned carb in the world is just a controlled fuel leak compared to what can be achieved with computer controlled direct injection,and timing of delivery of fuel an spark too,..easier no,cheaper no, but a hell of a lot better controlled tuning has to make a motor run better...dont see how it couldnt...

Look it up, it has been proven time and again that the peak power of an electronic fuel injected engine is not up to the peak of the same engine on a properly tuned carburetor. Overall power may be slightly higher but it can not match the peak. If you think a carb is nothing more than a tuned fuel leak then you REALLY need a new carb guy. Not trying to argue just pointing out facts on the 2 systems.

Don't know how this thread evolved from running a bb chevy into a discussion about fuel injection but anyway you must understand that an engine on the dyno and one on the racetrack is two different worlds.
Yes a properly built carburetor will make as much or more hp on the dyno but when you put in acceleration,deceleration,banking,left front hike and all the other g forces that a carburetor encounters under racing conditions the electronic fuel injection will win hands down everytime.
I'm not a fan of fuel injection because it's over the head of the weekly racer but physics prove it's better for racing.

Off topic, but yes the EFI is good for cornering or extreme angles but not well suited for dirt track racing. My argument against it would be cost, time involved in tech, and reliability. Rough tracks and dirt would be hard on it. I wouldn't want it. Now back on topic.
