    Looking to remedy Air Bypass Circuit (Vacuum lines) mix-up

    Hey Guys. In a sort of follow-up to an earlier post, my 1989 GT’s “check engine” light was on for the longest time after my buddies swapped out the engine (with another stock one) about 1.5 months back. The computer code reader said it was the “Air Bypass Circuit” that was at fault. That...

    Gas Pedal Stiffness / "Air Bypass Circuit"

    Alright, here’s the deal. Just shy of 1 month ago, I had the engine replaced in my 1989 GT (spun rod bearing). The following week after the swap, I noticed my gas pedal started to develop stiffness. Although this never happened before, I merely thought it to be a throttle-linkage “dry-up.” So I...

    Was this an optional 1969 spoiler?

    Yeah I thought that spoiler looked a little suspicious. I have never seen a classic mustang either in person or in picture with that wing. Good to know I'm not the only one! I know at one point Ford offered an option called the "Spoiler II", so I was thinking possibly that was it. Now these...

    Was this an optional 1969 spoiler?

    Hey Guys. Nothing too important here. Was just doing some research on 1969 Mach's (mainly for my dad - see previous post), cross-checking production numbers and such, when I came across this one site. At the top of the page it has a picture of a 69' Mach. It didn't strike me at first, I think...

    I need ANY and ALL info on the 1969 390 4v

    69stang351, as far as that coupe goes, it is up to you. The 390ci is definitely a torque king, and I'm sure you'd have fun with it, given it's driveable. What kind of condition is it in? Miles?

    I need ANY and ALL info on the 1969 390 4v

    96 DOHC Cobra, I decoded the intake manifold's casting number C6AE9425-H, and found out it was designed for a 1966 Ford Fairlane. That same site, http://www.gearheadracing.com/Reference/Ford/CastingNumbers/FordCastingNumbers.htm , says that Ford was famous for interchanging parts on the...

    I need ANY and ALL info on the 1969 390 4v

    Whats up Guys. I'm doing some research on my dad's 1969 390ci Mach 1. I know all the basic production numbers for 1969 but come to a rut when trying to find out how many fastbacks or Mach 1s came with the 390ci (and perhaps, 4 speed manual transmission). It also has the Shaker Hood option...

    I'm so stupid... the car cover goes on the OTHER WAY

    Alright guys, here's the deal. I'm 18 and I'm a classic stang lover. I drive an 89' GT. About 3 months ago I helped my dad in buying his first classic mustang since the 80's. This car would be a beautiful great-shape 1969 Mach 1 (390ci, hurst 4spd). Needless to say my Mustang-lover friends have...
