I couldn't find an answer so I hope someone can. I have 2 ports on the base plate, one small, the other large. The large goes to PVC valve. I have 2 ports on the throttle body, one small, the other large. The large with a big blue rubber vacuum cap. Where does the vacuum advance line go?

For those who have this engine/carburetor, what power valve have you installed? I've just discovered that the power valve I installed is a 45, which is what you get in the holley 3-1346 rebuild kit. I never did measure the vacuum at idle, in drive to get vacuum in inches and divide by two...

I noticed a cap missing on one of the Vapor canisters (there are 2 in my truck) and I got to thinking, do they ever need to be replaced? The Chilton''s manual 1976-86 ford pickups and bronco repair manual, page 4-12 fig. 11, shows two, 2 port canisters with an abbreviated part number 9C985. This...

1984 Ford Bronco XLT 5.8L 351 Windsor. I'm at the end of my rebuild. I replaced the automatic transmission because the driver side bell housing bolts and guide pin had been cracked and alignment would be out causing the flexplate to warp and fracture and could cause other damage to the engine...

I've spent the last 2 months completely rebuilding my 84' XLT in my redneck garage (next to my house in the shade ALL day). The old engine was weary and engine compartment oily and grimy. It has new cab mounts, all new body mounts with frame savers, floor pans, rocker panel, and a rear cross...
