Edelbrock intake/Holley carb question

Can someone help me out here? I have an Edelbrock Torker intake (part number 3785 base and 3789 top) and a Holley 8007 390 cfm carb on the way. I want to have everything laid out to do the swap without mulitple runs to O'Reilly's and Autozone, so my question is this; which brackets am I going to need to do the install? Will I need the 700R-4 Kickdown Throttle Bracket (Holley part number 20-121) or the GM AOD Kickdown Cable Bracket (Holley part number 20-95) or will I need both? If anyone else out there has done this, any help/advice/guidance would be greatly appreciated.

Re: Edelbrock intake/Holley carb question

oh nice well in that case i know you have to pull off the valve covers to do it but besides stuff to take off thats as far as i know on it you will need your gaskets of course um get some rvt silicone for it to thats about all i could say

i have a 2.8 and would love to know like how much of a performance inprovment you saw after doing the swap

You will need antifreeze, silicone, oil & filter.

Re: Edelbrock intake/Holley carb question

I know I am going to need that sort of stuff, but I need to know which throttle cable bracket I am going to need. On my S-10, the passenger side valve cover has a bracket built in to it that the throttle cable is routed through. I am replacing the stock valve covers, and the Holley does not use that bracket anyway. I will need one or both of the brackets I listed above. I need to know which one it is.

The folks at the store should know which one you need.
Why not use the factory unit bolted to the rear carb stud ?
Adjustment after the fact is another matter.
Don't touch the sheath release button, just reinstall the throttle valve assy as it is now..

Factory adj is to clip the unit together, then floor the throttle.
IF the trans shifts at this point, mark the sheath where it extends through the lock.

For a softer shift, move the sheath forwards giving slack in the cable.
For firmer shifts take slack out.
I bought a 88 Chevy 1500 in 89 for super cheap. In those days they would wear to the Hard Shift side of the adjustment. The shift would feel like it's gonna tear out the 3rd member.
A 2 minute adj and it was perfect.
I could get OD and lockup below 48mph, and 18+ mpg !

If you go too far either way the tranny will be stuck in 1st gear[700r4]
L460E's have no throttle valve cable.

On the silicone sealer, make sure it's "Oxygen Sensor Safe" I prefer Loctite Gold RTV.

Use more than the book says on either end of the intake manifold, I use about 3/16" bead as this makes a bulge on the inside and outside of the intake.

When putting a intake on my L-98 Vette motor, I used EXACTLY what the GM Service Manual said, something like 1.5-2mm
I inspected the rear of the intake with a mirror and found a gap where it did not contact!
Hence the increase RTV bead.
A larger bead will help keep it in place if you experience a backfire.

While I'm drivelling, a comment on the intake.

Is your Torker like the old ones, a 360 Degree ?
These work fine from 3500 rpm up.

If it's still new in the box, "consider" swapping it for a 180 degree intake with a torque curve from 1500-6000 rather than the Torkers 2500-7500.

I put a Torker on my Glastron Carlson 327 and it took forever to plane out then pulled fine from mid-range to 6000

Gluck

Re: Edelbrock intake/Holley carb question

What is often refereed to as the Torker is the 4BBL top for the Edelbrock Performer 60V6 intake. It's a dual plane/180 degree intake.

On an '84 it will be the 700R4. The AOD was a Ford transmission.

I'm okay, TILL YOU P!$$ ME OFF!
I've had two other S-10s, previously.
Had my '85 project, till I got hit head on...
A '92 extended cab, I got for my now Ex. She traded it when we had the kid.
On my third, a '93, that's mechanically sound, it's in okay shape. It's slowly getting better, though.

Always working on the 2.2L OHV LN2s and the 60 Degree V6s. If not mine, then someone else's!

I'm glad I'm not crazy. In that sense, anyway.
