4bbl carb/intake with cruise control 87 J20

Wanting to put cruise control on my 87 J20.

Which 4bbl carb & intake would be the best for towing and still work with the factory cruise control?

Also would like to actually keep all the emissions stuff operational, for the future smog natazi's.

I've heard the offenhouser intake gave the best low end torque?

Intake

Dennis I run the Performer but the Offy is good also. Stay away from the old SP2P even if you find one cheap. The stock AMC 4 bl is not bad either just heavy.

any holley or edelbrock with the typical universal throttle bracket will be easy to hook up.

I lucked into a free AMC 4bbl intake, weighs a ton, but came with everything including the brackets and a 4300 carb. Everything hooked up but I needed to swap in the old cruise control bracket.

I have a Holley ORA sitting on the shelf and it looks like it wouldn't be a big prob hooking it up.

Check out this thread, it has a pic of Ristow's set up for the Holley:http://www.ifsja.org/forums/vb/showthread.php?t=98829

Which 4bbl carb & intake would be the best for towing?

Wonder if can even find Offy intakes anymore, I saw a NOS one few months ago.


Brett, the cruise stuff changed in 86.

Offy

Good deal, I figured I'd have to hunt one down.

Would I still be able to keep all the emissions stuff on the truck?

Which Offy intake should I get?

Or Edelbrock?

I didn't see an Offy w/EGR. You may have to go with the Edelbrock Performer EGR.

The Dual-Port is the best for torque and economy, but no EGR. Performer EGR intake is the only EGR I've seen, other than a rare SP2P EGR intake on the forums before, but no good for towing.

I would suggest Performer EGR or Offy Dual-Port.

Check with Offy on the Q-jet intake, I think they may have dropped it in a Dual Port design ... still have the Holley pattern Dual-Port.

I don't know what all would be involved with hooking up cruise with a Holley or Carter or Edelbrock carb ... a call to their tech support lines would help.

i think the dual port for a V8 has horrible fuel distribution. especially on the secondary circuit. i'd bet a dyno test would show a performer intake better all the way around. probably a great I6 intake though.

it's pretty straight forward if they have the typical universal throttle bracket,which they've all had for years.

Economy

Thanks for the help guys.

Sure don't care much about "economy", just love to hear the secondaries kick in and listen to the flowmasters make their music.

IF/When the 360 in the 36K mile truck goes out or loses compression in any of the cylinders, then it will be time to build a reliable 401 again, but make it look factory.

probably swap the one out of Scrambler and put the Indy Aluminum block and heads in Scrambler.

Which 4bbl carb "looks" factory but is still performance carb?
How many CMF would be best to run for towing power?

4300 motorcraft was factory on the cars and i believe early jeeps. decent carb too. they were a conservative carb cfm-wise (500-550cfm-ish? 600 max),which is good for towing.

i (think) got one all apart in a box if you want it.

Depends on what you want to run it for. It's an economy intake and good for about 4,000 RPM MAX. It's not designed for towing ...

Airflow....they have SMALL ports on the intake.

Works fine, but like Greg stated they run out of oompf about 4k.

I'm sure port matching it to the intake side of the heads would help it a bunch.

Which is the best intake for the Motorcraft 4350 ?

What's the bad part of having a EGR, does it affect performance much?
Looking for torque, low end power, and freeway passing while hauling a baby Jeep or Gladiator on trailer.

If so I guess I could machine a hole to put the EGR in to look factory, but it wouldn't function, which would be OK. Anyone ever done that?

the 4350 is it's own goofy butterfly arrangement. stock intake for that carb is best.

4300 is a square bore carb,so it'll fit em all. performer intake is about the best available. get an egr one.

EGR does not affect performance much. still,i like to run without em.

Realiable Carb ?

Oh....most important, I got enough Jeeps to build and keep running and I'm no good with carbs at all.
So I'd like to pick carb that is realiable, I.E. not tuning it all time.

That's probably more important than performance with this truck.
