Edelbrock Performer Intake

[rt9]

Hi guys. I've been looking at this intake manifold for a couple days now. I want to increase low end power through 2500 rpm.

Thinking of hitting this in stages. Intake and 500 cfm carb first then Phase 2 install the Performer Plus cam. (Need assistance on roller or tappet.)

Heads,,,,, later on. HEI?

Your thoughts would be appreciated ? Motor is 289 stock, 74000 miles, all original.

If your rig ever sees dirt you might consider a Quadrajet over the Edelbrock. Otherwise it's a great choice. I've got the 600 CFM Edelbrock and it's great, just bogs a little when it get rough. Also, if you think you're going to do heads I'd consider doing them at the same time as the cam since you'll have it torn apart. Cam will be for a flat tappet setup.

All of that said, given how stock your rig is I wouldn't touch a thing.

Yeah I know,,,, but It REALLY could use a touch more power. So I'll probably pass on the heads, for now. Plus, from what I've read, I would just want to have the stock ones "worked on".
I forgot to mention headers. Probably will install headers after/with the manifold/carb, drive it and then decide on the camshaft. Nothing major or radical.

The wife says if I get to with it, she's going to call you guys and schedule a bronco intervention!!

That's a great setup, I have the same exact intake, Carb, and headers.

Intake and Headers were bought used, Carb was bought new (rebuilt) and worked great right out of the box.

[rt9]

Cool - so at least I'm headed in the right direction. What headers did you use?

500 or 600 CFM?

Our interventions usually look something like "Yeah, that's a great idea! Go for it!" Your plan is a good one overall. A carb and headers may wake things up enough that you're happy with power. You may also want to consider getting the carb tuned. You'd be surprised how far off the tune can be, especially at this altitude, and still run fairly well. With a stock air cleaner the edelbrock will still have a fairly stock appearance, and you can hang onto the original parts to sell with the truck if you ever decide to.

Justin - thanks. Yep, I've kept all the parts so far that I've removed, except the original steering wheel. Damn that was stupid...... I'm actually planning on tearing into the original PTO winch in a couple days to see what's wrong with it. Should be a good ole messy time.

Before I started ping any aftermarket stuff on, in the name of power gains, I would run a compression test in the motor. No sense in spending money on upgrades if the bottom end is on the way out. Not that 74k is a lot of miles, but you don't really know what kind of miles those may have been.

If your compression looks good across the board, then move forward on other fronts.

What gears are in the truck right now?

Carb is a 1404 500cfm with electric choke and 1" spacer,
Intake was bead blasted from Gunni,

Headers and exhaust are Justin's old ones. Name brand escapes me but I can look tonight...

Thanks - I was looking at bronco hut shorties, but they are pricey! I just put new stock exhaust pipes on,, so it would be nice to find a set of headers that will bolt up.

Zach - yep that's a good idea. I will do that first and make sure the compression is good all around. Good time to check (replace) all the plugs too.

I ran a Edelbrock 500 cfm on my 68. On the street it was great, but off road it would flood out when climbing. I found a utube that showed a baffle installed between the float bowls. I gave up on it and installed a Holley 570 cfm.
Best carb I ever had was a Holley 500 cfm 2 barrel. Wore it out and stripped out the float bowl screws.

That's funny Bob, I had the same (opposite) experience with my old '68. I had rebuilt the Holley, did the 4x4 upgrade junk, still sucked, and ultimately went with a 500cfm Edelbrock 4bbl and I never had any trouble off road! ;)

These are the things I have done to both broncos and it made a huge difference. The big one was the vacuum hose plug between the float bowls.

You know you want efi.

[rt9]

Looked at the FiTech system. Dont drive the bronco enough to justify it,,,,,yet [SMILING FACE WITH SMILING EYES]

Not everyone is ready to abandon 100 year old technology on 50 year old trucks.

I'm willing to bet there will be a bunch of Bronco owners in a few years wishing they'd kept close to original. Kinda like those guys with tri-five Chevys all tubbed out, glassed and sporting LS1s.

But, as long as you're having fun with it...

[Justin]

Totally agree. If I had a stocker it'd have a 2 barrel Motorcraft.

[rt9]

And so the intervention begins.... lol. I love it.

I'm keeping everything cleaned and boxed for that day when I change it all back.
