Fuel Injection and Cowl Induction

Is there a way to set up a fuel injected LT1 to breathe through the stock cowl induction hood on an 82-84 Trans Am?

The idea of swapping in a fuel injected LT1 because of the fuel economy and performance advantages of EFI sounds really nice, but I'd also like to keep the hood intake functional just for nostalgia reasons and because it sounds cool when it opens up.

Re: Fuel Injection and Cowl Induction

Off the top of my head, I'd say that it's possible (you'd have to have the intake tract make a 180* turn right in front of the TB, then place the MAF {if applicable} & then have the tract turn upwards to tap into the bottom of the power-bulge hood), but I don't know how efficient it would be...

In addition to the number of turns that the air would have to make, you'd also have a tough time trying to keep the air from getting noticeably heated as well (not a killer issue, but it degrades efficiency/performance). Although if you handled those issues, then you could likely fab up a way to retain the flap-opening as well, I'd think.

It definitely IS a cool "theoretical" idea, but I'd say that there are some practical challenges that you'd have to overcome.
