I have a million tabs open right now from all the research I have been doing but I read somewhere that the Ranchero and Gran Torino came with the 351C CJ and Duraspark beginning in 1974 so I am making the conclusion/assumption (*** out of u and me) that the whole kit and kaboodle was just...

I have decided to hold onto the convertible since I'm not desperate for the money so there's really no reason to get rid of it yet. Hopefully in the next couple years I can find myself some garage space and get it to Vegas to start working on. Anyone in Vegas and have garage space for a rusted...

Finally got this new to me Mach 1 running well enough to drive around the block so I figured its time to start a build thread! You can view my intro post here: https://7173mustangs.com/threads/new-member-just-purchased-71-mach-1.45749/ And the issues I have been having with the engine so far...

While waiting for the timing set to arrive, I wanted to keep making progress: I stuck a bore scope down in a spark plug hole and I am about 95% certain this engine is a 74 CJ. The picture wasn't the easiest to decipher but there appeared to be dished pistons and open chamber heads. No surprise...

Block Casting is D2AE-CA Production Date: 2k26 (26 September 1972?) According to Enginelabs.com: D2AE-CA – 1972-1974, 1971-1974, 351 Cleveland small-block, 4-bolt mains, High Output, Cobra Jet, Boss I know I need to look in the pan to verify 4 bolt main but that's cool. So how do I figure out...

DOH! I knew the casting numbers were under the head but I thought they were under the exhaust ports not the intake. Missed opportunity. I did go ahead and pull the valve cover and get the date code which indicates May 73. I was also able to get the vin on the back of the block. I will pull the...

Alright, so after being away for work for 2 weeks and barely able to think about anything else but working on the Mach 1, I was able to put a few hours of work in. First I installed the edelbrock intake as that was definitely an issue to have an intake and carburetor that matched. I removed the...

Just speculating here but the hood of the car is painted in the Boss color scheme. Maybe a P/O was going for a Boss tribute? We will see what the numbers say when I get back to the car! EDIT: This could also explain why the (potentially) 4300D Spreadbore carb is missing as well; as those seem...

Ya'll have already shamed me into buying legitimate bolts 😓

I wanted to add what @Sheriff41 responded in my other thread to keep it all in one place: "I had responded to your post so I'll try to recall what I typed. Your Problem sounds like you may have a timing issue. Set your base timing to 16° and see if it helps clear up the power and backfiring...

Thank you everyone for your responses. It has been very informative and helpful! I am actually on a work trip right now so I wont be able to work on the car for another 2 weeks. Will definitely post an update when I get my hands dirty again. I went ahead and purchased the Pertronix III igniter...

@Hemikiller I see my post. Thank you for restoring and solving the mystery. Should this one get the axe to eliminate confusion?

I sent a message to an admin and hopefully they will be able to see what happened

I mean, technically my second post: I asked some questions about issues with my 351c in this engine section of the forum: "Hello all! This is my first technical question post. I just purchased a 71 Mach 1 and need advice on troubleshooting steps and where to go from here. Quick backstory: The...

I made my first post yesterday about a new to me 351c and I was receiving really helpful answers that I really appreciated. I woke up this morning and the thread is nowhere to be found. What happened?

Thank you for the kind welcome! I posted my first technical question in the engine forum but I will ask something else here: I now technically own two '71 Mustangs: the rusted out convertible, and the new to me Mach 1. I am pondering what to do with the convertible. It currently lives at a...

Hello all! This is my first technical question post. I just purchased a 71 Mach 1 and need advice on troubleshooting steps and where to go from here. Quick backstory: The car is an M code with Ram Air so I am assuming the ram air was aftermarket as the wiki says the factory ram air cars are Q...

Hello! I am new to this forum but have used forums extensively in the past for other projects cars. I just wanted to make a quick intro post before bombarding the forum with questions. My journey into the world of the 1971 Mustang began when I was around 10 years old (27 years ago) when my dad...
