You specifically want a carb or just a carb "style" intake and still run Fuel Injection?????

There's a few intakes that would fit but I believe they would all need to be modified to fit an LT1/LT4 style intake bolt pattern.... Might wanna call Port Pros (sponsor on this site) for more info. I'm having them do my Edelbrock Victor "E" manifold but i'm keeping fuel injection and just running a much higher flow single plane manifold for the upper RPM power.....

Another one from the "Not to get on your case but" department....

Have you ever even looked at a dyno chart of this? Or even drove around a motor with one on it? I'm guessing by the answers to this thread, that's a big no.

still haven't said whether or not it's going to remain fuel injected or if you're going with a carbuerator.....

If you're going to keep your fuel injection and want to run a single plane intake I'd say have either Port Pros or Bret Bauer do up a Victor "E" manifold for you..... has fuel injector bungs cast into the manifold and you can buy fuel rails that fit it... it's basically a victor jr setup for EFI.... It would need to be ported and have the stock holes welded up and new holes drilled for the LT1/4 style bolt pattern on the heads....

#1. Remember that a N2O motor is still a NA motor just with more O2 injected into the motor.

#2. Victor E intakes I don't do or recomend. They don't have the cross sectional area that most setups need without crazy porting, they weight about twice what a converted single plane will weight and they definately need a carb spacer to get the right transition into the inner runners.

#3. I wouldn't do this unless I had a bottom end built as well.

Anyone have good luck out of the GM performance parts carb intake for LT1's?
I'm building a carbed LT1 for another car I have, but didn't know if it was worth spending $250 on over a single plane intake and having it machined to fit?
