When my ex's daughter was still in diapers she wanted to go in "the big red truck"
I'd find a good size parking lot, she would sit in my lap and tell me to go faster or slow down. She caught on really quick, even at 18mo. 
Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake. Too much other stuff to mention. |

Nice!! My girls are not mechanically inclined as much as my son and it took them a lot longer to do the things he does now.
We were just parked in the garage and he was moving the steering wheel with the truck running. He grabbed the automatic shift lever and almost shifted it down  I think there is a safety built in just like the bullnoses but I need to double check.

OK one more thing to report on the EGR front.
I have now established that the 460 holds excellent vacuum when warm, steady 22" at idle. Still not enough to leak through the distributor  I tried to run with EGR after things warmed up fully and it ran horribly, even with vacuum advance tied straight to manifold vacuum. The 460 would not even idle with EGR functioning, even though I'm mimicking the stock 460 vacuum diagram. I tried doing the ported vacuum as well to perhaps simulate the scenario where it could be only in effect while cruising. It is able to run 'fine' at about 1500 rpm, but the vacuum gauge wasn't very stable. It was bouncing around just a hair. Without EGR, both idle and cruising scenarios are performing significantly better based on the vacuum gauge. I do not have pinging issues without EGR while cruising. Does this mean the 'stock' Cardone distributor is already curved to not use EGR ?

22" is very good vacuum at idle.
 But I think there's something wrong if you are getting exhaust gas into the intake at idle. I'm pretty sure that you are only supposed to get exhaust gas when under partial load, meaning cruise but not idle nor WOT. However, if you aren't getting pinging then your distributor may be set up for a non-EGR system, although that would be surprising. Still, if it is running when w/o EGR then I'd leave EGR off.

That would be nice to see!
The one below from my other 84 460 truck is what I’ve used as a reference so far. I had it routed in a similar way however the VDV is not present at the moment, but I have a couple of spares that could be used. So far with my distributor it appears there isn't sufficient advance to use EGR.

Another piece of info for 460 swap into 78 Bronco to document.
78 vs 79 Broncos. The 79 is more bull-nosey in that it uses a throttle cable with spring. The 78 is old school throttle rod. Thankful I found a 60s mustang throttle rod that worked finally. Part# C5ZZ-9A702D Found also differences in emissions. No EVAP system in 78, while 79 had similar EVAP system as Bullnose.

Moving onto the part that I hoped I would get to one day
 The rear half floors are perfect. Just needs a good cleaning. The driver and passenger side floor pans are also very solid and sturdy, except for surface rust and pitting in some areas. I am not sure if Dentside sheet metal was thicker or what but it is really sturdy even in the pitted areas. I used a wire wheel to go over them pretty hard and no surprises. Passes the screw driver test as well. Thinking of - using wire wheel to remove anything thats loose off the floor, - and then 3 step POR-15 (Gray), - and then primer, and yellow color matched paint. Once this is done I'm going to do an ACC carpet set with sound proofing and water proof mass backing. What do y'all think of that plan ?

I will be painting it myself. I'm going for an overall patina look so it won't need to be perfect (I need to consciously ensure I get a patina finish on the hood and not make it look too nice). I will color match the hood and some minor touch ups, that's about the only goal I have paint wise.
I have thought about media blasting. I probably will end up doing that, is there a good portable setup available ? This one looks like a decent starter option in combination with glass beads... Just need respirators I suppose and a good cover and clean up. https://www.harborfreight.com/portable-abrasive-blaster-kit-37025.html
