I had a 73 Road Runner with a center console. No strap on mine either. Must be a customization added by someone.

Hope you have a great one! :moparsmiley::usflag::bday::usflag::moparsmiley:

My deepest condolences. My wife and I have only been married for 37 years, and I can't imagine losing her. As others have said, and as painful as it must be, thank you for letting us know. I wish you and your family peace.

Caster is the measurement of how far back the spindle leans. If it is straight up and down (0 caster) the car turns very easy at slow speeds but it will become twitchy at higher speeds. The more positive caster (i.e. leaning backwards) you put in, the more the car will want to go straight. With...

I had a 73 Road Runner for 42 years that was purchased in 1979, so it was original except someone had put a 2 barrel carb on it to attempt to get better gas mileage during the gas crisis (wrong move, but that's what they did). Anyway, my 73 had the lap belts pulled out, wrapped around themselves...

I seem to recall that most oils for modern engines have about 600 PPM. This fits with the "max of 800", as they probably want to stay we clear of the maximum. Also, if I recall, ZDDP is not good for catalytic converters which is why it as been reduced in modern oils.

Assuming that it has fast acting ZDDP, that sounds to me like a good amount for a break in oil. In my opinion, I would use an oil that is blended with higher ZDDP levels and not add separate bottles of ZDDP additive. As illustrated by @khryslerkid's post above, adding ZDDP additives can be very...

:popcorn: Subscribed. I don't have a 3D printer, but I am getting more and more interested in getting one. If I could scan old Mopar parts and then print them out to replace or repair certain areas, that would be really cool. I'm interested to learn more about costs and what can be done.

My father-in-law and I are very interested in the whole ZDDP thing since he builds engines and has a machine shop. We DON'T want to wipe camshafts on engines we have built - that is expensive! Anyway, we have read a lot about this and spoken to oil company representatives, especially at trade...

A key thing to check here is the fit of the intake manifold to the engine. You've probably already installed the intake manifold but it is good to lay the intake in place bare and then use a feeler gauge to see if both the intake and head surfaces are parallel on both sides. An error of .004" or...

Few people will know the difference, and those that do will likely think it's cool. Those that want to nitpick about it being incorrect for the year: It's your car - do what makes you happy!

As it is, there were very few 440 Road Runner/ GTX cars made in 1973. A number like 267 comes to mind but is probably wrong. Regardless, there were very few. Sunroofs were also fairly uncommon, as is blue with a red stripe. I'm looking forward to pictures of the car!

Hope you heal quickly and well!

What, us car guys modifying stuff?!?

Barry's GTX engine is getting close! :xscuseless:

More on building my buddies 440: Mopar Stage VI heads are raised port heads, so they need a spacer to adapt to the intake manifold. See spacer in the picture below. But they also mean that a standard valley pan cannot be used since the ports won't line up. We bought a valley pan from Edelbrock...

The effing mice do more damage to our old cars - they especially screw up interiors. I hate the little critters!

Best I am aware of is AAA Premier. Any car I am in can be towed for up to 200 miles free. For both of my trips across country, I figured that would be enough to get me somewhere where I could fix the car. If any of you guys go on a long trip, take me along for the towing! :carrot: In 2022, I...

To add a bit about startup: With a flat tappet cam, I would use old, weak springs for break it. Yes, it might seem like a pain to have to change them after break in, but no where near as much of a pain as it is to fix a wiped cam. Even 300# open spring pressure is too much for break in. An...

Mind you, I am only speaking from memory here but have no pictures, data or proof... I recall seeing my first blue with red stripe Road Runner circa 1984. I had my 73 Road Runner (then Tahitian Gold Maetallic, AKA brown) with a white stripe. Anyway, the blue with red stripe was very striking...
