Anyboday maybe have some experience and or ideas on which intake would perform better, edelbrock dual quad or stage V dual quad, both with port efi?

Would be for a streetcar with 528 KB Hemi, .610" roller cam, Stage V cnc heads with roller rocker setup, 10.5 cr. etc. backed up by 6-speed T56. Most used rpm range would be around 2-3k.

ANy input or experiences here?
Thanks guys.

Port EFI? Then why use a dual plane intake? I'd think you would want single plane all the way. It seems like a pain to put bungs into a dual plane intake.

The Edelbrock is a single plane intake, I'm pretty sure the the Stage IV one is too.



The Edelbrock has flat pad cast in over the intake ports to install injectors.




I believe that you can even order it new already machined for the injectors.

Stage V is a single plane and has an efi manifold that is ready for port injectors.

I have used both manifolds on several EFI HEMIs. They both work well. It's a minor point, but the Edelbrock has an air gap which allows hiding some EFI sensor lines and even the regulator return line if you mount the regulator up front between the rails. Also the Edelbrock TB spacing is better suited for normal dual quad air cleaners and you can buy the matching fuel rail kit from Edelbrock which saves you the grief of making your own for the Stage-V.

Cool deal, I didn't realize that Edelbrock had introduced an EFI version of that intake. Looks like that is the way to go. Last time I looked at Hemi stuff the Stage V intake was the only single plane one around.

Rich brings up a good point on air cleaner spacing and stuff like that. I've gotten into that mess before using the Stage V intake and then trying to find an air cleaner that fits and works with a fresh air hood.

Tim Banning at FHO may offer a Stage V intake specific air cleaner setup to work with OEM hoods. There's info on his website about this.

Finished up this one awhile back using the Eddy. The stock air cleaner base fit's the TB spacing perfectly. The Eddy rails are made for the manifold and fit correctly.

Looks really nice. What ECU did you use with those Holley throttle bodies? Is the linkage 1:1 for the throttle bodies?

Customer wanted a Dominator for dual O2's...kinda overkill. Yep, went with 1:1 to start. Tip in is a little sudden, but not as bad as I thought it would be. A progressive might be in the works once he starts driving it a little more.

Where did you get linkage for them? I have a tunnel ram I am going to be using two of those TBs on soon.

Monte Smith (RIP) told me to go with the Edelbrock Dual Quad Manifold for my Hemi, and he told me the Holley 112-602 Throttle Bodies would be perfect...He also supplied me with a list of parts so I could go with either the Holley HP or Dominator ECU.

He told me I could run progressive linkage, but he did not think that was necessary for a 3500 lb car with a 4 speed.

For my 440 in my GTX, he told me to buy the Indy Mod Man MPFI intake, and again, use dual 112-602 Race throttle bodies.

So there must be a setting in the Holley ECU for dual throttle body setups? I haven't looked that far into the instructions yet. I wonder if the ECU cares if the linkage is 1:1 or progressive or maybe it just figures it out by looking at the TPS.

Yes, if your using two Terminator throttle bodies (injectors in the TB), but if multi port, doesn't matter. You just pick which TPS and IAC you want to use and just leave the other pair unplugged. Linkage doesn't matter, as your just opening the "air leak" faster or slower. Your target A/F will be met either way.

Yes he has

Can you post a picture with the air cleaner assy installed? Thanks.

Here ya go!

That's my cup of tea, looks stock, but modern. Thanks.

The 'air gap' part of the edelbrock was something pointing me into their direction. Might be cooler inlet air and the reason to hide some more wiring / lines etc. but was just wondering if anybody had more input performance wise in the lower rpm range.

Thanks for the input!

The reason Monte had me go to the Edelbrock for the hemi was because I could machine off the valley cover, and keep my Indy 2 piece valley cover...it worked great, and has plenty of room for the EFI wiring.
