Has anyone done this EFI Conversion with the old shcool intake and their elbow? Its very intrigueing. Just wondering the scoop.

Look up single planes on here.... lots of info. I've done a lot of them.

That elbow will allow you to use your stock style throttle body (58mm, monoblade...etc). In turn makes the conversion 10 times easier than if you had to get the PTE round elbow and a Accufab 9mm round T-body. I wish this elbow would have been out when I did my conversion. Then I could have kept my monoblade.

I ordered the 58mm Elbow for my Conversion last night.

would that elbow with a larger stock-style throttle body and the GM performance parts LT1 carb manifold be of any benefit to a mild heads/cam, stock bottom end motor?

how about a completely stock motor or cam only?

Yea..seems like a general question, but what are the advantages of this over the Factory Piece? Just alot more HP potential? Would it really be of any benefit on a mostly stock motor? Or something to wait until a full build-up ?

After Researching the whole EFI setup, it seem most people only do the conversion with bigger cubes and a big race motor.

Gotcha. The stock intake can support a "fair" amount of power on its own right? Especially if its ported?

Fair? I think it can support a damn good amount of power. But the Single plain just frees up so much more power in the induction section of the engine.

Mine is not a big bad race motor. Well it's big and bad but not for racing at the this point. I wanted to build this motor for the street mainly. To be as my daily driver. We will find out in the next couple of weeks how streetable it will be. Mine should be more streetable than tony's hopefully.
Being hydraulic roller and yanking the linkage off my stock Tb or whatever you call it on the side of the TB. It should have the same opening ratio as stock, and I think that will help out on tuning.
we'll see

A few advantages of the single plane vs the stock intake are that the setup will make more TQ thru the RPM range due to the longer runners. It also has better distributon to each cylinder and more ability to flow air.

I have the Offy super-sonic intake for my 425 at www.intakeelbows.com right now being converted for EFI.

I'm building my own intake elbow to use an LT1 throttle body. One question I've had is how much power can a 52 or 58mm throttle body support?

I'm building the engine for 550-600HP and checking the Megasquirt website, they had a calculator for how much power a given throttle body size could support and I thought it was a bit off. According to their calculator, a 58mm throttle body will only support around 360HP??

Any thoughts?

Thanks,

The 58mm is a twin 58mm. The calculation is more than likely only calculating one side. I know it flows around 1000 cfm which can support 700 rwhp and even up to 1000 rwhp forced inducted.

Thanks, I just wanted to make sure I wasn't shooting myself in the foot going through the fab work for nothing.

Will that intake and elbow fit under the stock hood?

i was tinking of doing this set up on my 396CI build but now i am thinking of going bigger like a 408CI....everyone that i have talked to have told me to go with the super vic intake. i am looking into others but mainly going for a long runner set up for the best all around torque.....
