hey, just wanted to let everyone know, summit does have these adapters in stock. i was surprized, seeing jegs and paw wanted between 2 and 4 weeks because they had to be specially ordered. i ordered the holley tbi to spreadbore adapter, but it happens to work on both spread and square manifolds (i was given a edelbrock performer spreadbore intake). $45 is a hard pill to swallow for a machined piece of aluminum, but i'll survive. one step closer to finishing the 400 swap. now just gotta finish my tranny......

 

i'm just wondering if this will all fit under my hood...cause I have a eldebrock performer manifold on the side. #2104 if I put the adapter will it fit?

 

i'm hoping it will fit. i believe it should because it doesnt appear to be higher. i havent closed my hood all the way, let alone put the air filter on because i'm still in the final stages of swapping in a motor.

 

i have the edelbrock performer intake and the holley adapter. My stock air cleaner fits but i dont know about an open element. I also had trouble with the cables being the incorrect lenth. Youll probably want to make a custom bracket for your tv and throttle cables. Egr doesnt seem to work easily, either.

 

i have the luck of getting a chip without egr, so i'm not too worried about that myself

 

I have the Performer RPM intake with the Holley adaptor. A 14x3 adaptor fits under the hood without a spacer, but I couldnt fit the stud/wingnut on there using a Summit open element.

 

Chuck....
Can you provide the part no. both intake manifold and TBI adapter...
Thanks...

 

Performer RPM Vortec: EDL-7116
Holley Squarebore - tbi adaptor: HLY-17-45

 

that perfromer rpm intake is for the L31 vortec heads only. Just get the regualr performer rpm intake if you have your stock heads.

 

Thanks

 

Performer RPM (non-EGR) #7101

That'd prolly be the one you're looking for.
