77 Engine bay clean up...what can go?

[XQIZT]

Even though we had discussed an LS swap into the 77, we're gonna make that more of a "long term plan." Right now, we're gonna swap in another 350 (from an 85) and keep the carb on the top. 200r4 trans will give me the OD gear that we wanted as well.

This is Florida daily driven car. NO emissions testing to worry about.

EGR...can this whole system be eliminated? Obviously, I'd cap all the lines that would otherwise cause a vac leak, but is there any harm?

Heat riser and shielding...on the drivers side exhaust manifold. The flexi pipe leads into the air cleaner housing. Can all this be kept off?

Cruise control is getting ripped out too. No need for it.

Is there anything else that can be deleted/removed to clean up the spaghetti tangle of hoses and wires that live under the hood?

Thanks!

The EGR system can be removed safely, but you will want to remove the EGR Valve as well and buy the block off plate.

The flex hose from the drivers side to the air cleaner can also be removed. It serves to send warm air to the carb for cold starts until the engine is warmed up, that shouldn't be much of a problem in Florida

That will remove one vacuum hose and the stovepipe, not much cleaning out of stuff, but its a start. Most of the vacuum hoses are for the headlight system. Check this thread for an option on headlights :

Post #3 is the main one I'm considering doing to my own car.

There is a large group of wires and vacuum hoses that run across the top of the vacuum booster, and I found that all of them can be routed UNDER the boosted to clean up that corner.

I also moved the horn relay into the wiper trough in the indention, and just rerouted the wiring in to it.

I did plenty of other things to clean up my '77, but since it's so heavily customized most of the suggestions won't apply to your car.

Thanks guys. Got the motor and trans out today. Gonna be building the new motor soon and getting the thing back on the road.

Suspension rebuild is next. Figure this is the easiest time to do it. No motor in the way.

When did i miss the engine choice? What's going in?

You didn't miss it, I just haven't posted anything about it yet. We're going in a slightly different direction for a number of reasons. Basically putting in a 85 block and heads with the ZZ4 base and Rochester Q-jet. 200r4 trans driving it all. Far simpler...and cheaper...for now. Long term, we'll make the LS swap. I'll start a thread on this soon.

Are you re-using the Q-jet you just rebuilt? If so, your new configuration will benift from re-jetting and some re-setting/adjustments.

Yup, reusing the ol' Q-jet. How should I rejet it? What are the new settings?

I assume you used the rebuild kit and the parts that came with it. With your new the cam duration and ZZ4 heads and slighly better exhaust flow I would step up the jetting from the stock size. What was listed as coming in the kit? I sent my Qjet out to get fine tuned after I rebuilt it. I paid $80 for flow-bench calibration and run on a test engine connected to a dyno. I would estimate in your configuration running no less than Main Jet size at 76 - main metering rod size 44

Currently doing my 77, for me its less is more. The question was, what can stay?
