        • Well my shop warmed up to 38 or so and the wind was calm so I decided to pull the carb off.

          Unbolted the stock carb, pulled it off and carried it back to the garage. Came back and looked at the intake.

          Hey, that looks funny.

          Somebody installed a square bore gasket on a spread bore intake!

          Ran back to garage to check carb. Spread bore! Dangit!

          It's no wonder this thing would not run worth a flip.

          The Ford spread bore has the same bolt pattern as a regular Holley. So I have 4 options from cheapest to most expensive.

          1. Buy an open spacer, bolt it on and never look back.
          2. Use the square bore intake I drug out of the backyard yesterday.
          3. Buy a Transdapt 2199 adapter made just for this reason.
          4. Scrounge up an aluminum intake.

          Pulling the intake would be nice because I could check out the condition of the inside of the motor, but the immediate gratification part of me wants it done now! It would be super nice to get that crusty mouse poo intake off and plop on a cleaner one. Big picture.... big picture.... gotta see the big picture.... Uncovering the sins of past owners is always interesting.

          Square bore intake.

          • Those adapters are cheap, and add a thermal break of sorts to the mix. That break might come in handy come summer?

              • I have been reading that the stock intake is actually pretty good for trucks that stay under 4000 rpm 99.9% of the time.

                • I have to agree with an adapter/spacer. If the compression looked good, drive it some and then decide how far you're going to go with it.
                  I had to grind on a cheap squarebore aluminum spacer to match the spread bore holes, but it wasn't a big deal, to get it a square bore carb to work on the father in-laws '77 Lincoln.

                  I know I'm a broken record...but if you pull the intake...you're a 1/4 of the way to swapping in a cam...and in my experience, it was totally worth the effort.

                  • I am definitely going to swap on the other intake. Swapping intakes is no big deal really and it will afford me the opportunity to put an eyeball on the inside of the motor and in particular, the camshaft lobes. The other intake, even after sitting in the backyard (now in the bed of the truck) for several years is already cleaner than this one is! If you know anything about me you know that if I short cut something, it will drive me absolutely nuts until I back-up and do it right.

                    I'm thinking pull the valve covers and intake, clean the square bore intake and vc's good, maybe shoot some blue paint on them and reinstall. moparman63 txt'd me earlier that his friend said he had a set of headers for a BB truck. I'm not really ready for that, but hey, if they are available cheap, I might snap them up.

                    Hey looky, there's a D0OE CJ intake on Lubbock's CL for $100. Too bad it's 100 miles away.

                    • Well get a friend or use your engine hoist!! Those cast iron intakes are HEAVY!!!! Especially if your bent over and reaching out!
                      I DON'T want to see progress slowed up because you hurt your back!

                      Does it need an exhaust anyway? Might be the right time to add headers! Although on a parts chaser, do you want to deal with header leaks?

                        • Yes I know they are heavy.

                          The driver's side head pipe swings back and forth. I don't know it it's a destroyed donut or rotted pipe or what just yet. The headers are being offered for next to nothing, so they are worth a look.

                          I have had very good luck sealing headers on the Mustang, so hopefully this truck would be no different.

                              • My impatience got the best of me Tuesday. Actually I really want to make sure it will run properly before I pull the intake off. So if I determine something else is awry, I can tear in take care of it all and move on. I ran to Autozone and picked up a Spectre carb spacer ($20) that can be converted from an open to a 4 hole. Pretty neat deal. This is good because to test fit on the spread bore intake, an open spacer is what I wanted to use and on the square bore intake I need a 4 hole to install in place of the egr spacer.

                                New carb in place.

                                5.0L HO 4v! I dug out the Mustang's original air cleaner and unbolted the snorkles. It is aluminum and weighs about a 1/4th of what the stock steel one does. haha

                                It would run if primed, but I never got it to pull fuel from the gas tank. I should have filled the bowls through the vent tubes, but I just ran out of time to work. It may be a fuel pump issue but it is more likely just out of gas. I didn't put much in it the last time I messed with it.
