74 Road Runner with a 360 that won't crank over with the key. I can jump the contacts on the starter relay and it will crank. I ran a jumper from batt neg to NSS terminal on starter relay and still no start. This tells me that the NSS is not the issue. I measured voltage at the yellow wire while...

I have a 74 roadrunner with a 5.9 mag in it and I've noticed that it sometimes takes a couple key turns back and forth to get the starter to fire. It's been getting worse and worse, and now it doesnt start. Starter is new about 5 months ago. So I'm thinking it's the ignition switch or wiring to...

I'm rebuilding a 5.9 magnum engine to put in my 74 road runner. I have the front accessory brackets from the 318 that I pulled from it but I'm a little confused on how these brackets go on because things don't seem to line up very well. I took pictures of it when I was pulling the 318 but the...

I have a 74 road runner and I put my fender tag code in an online decoder and everything made sense but I had a question on A88 and V9W. A88 is the interior decor group. What did that consist of? V9W came up as unknown, I was researching online and someone said it was some trunk lid stripes...

I have an eddy 1406 600cfm carb on my 318. Rpm intake, 302 heads, headers, dual exhaust, ~340 cam, FBO ignition. When I slam the throttle pedal from dead stop or light cruise, the car bogs out and nearly dies. It idles great, cruises great and is great at WOT, but bogs down at the transition to...

I have a 74 318 road runner and I went through the front suspension over the winter and put a pst front suspension kit and bilstein stocks. I just got my car aligned (it was way out of spec) and now the steering feels really loose. I knew it was always pretty terrible but now with greased up...

I'm putting new oem style disk brakes on my 74 Road Runner and I noticed that my new rotors already have bearing races pressed in. I just bought new inner and outer wheel bearings and they also came with races. So should I remove the races that came with the rotor hub and replace them with the...

I took my lower control arm spindle to a shop to get the lower control arm spindle and bushings pressed in but I wanted to make sure they are in right. Are they supposed to stick out this far? 1974 Road runner https://photos.app.goo.gl/rZ2Uayl6IKjegnaJ3

I have my k frame out because it's getting cleaned up, welded, and painted and I just replaced the oil pan gasket and rear main seal while I had access. Is there a good way to start the engine with it just on Jack stands? Id like to check to see if it leaks while I still have access to the oil pan.

I've got a 74 road runner with a 318 in it and I can't get my temp and oil gauges to work. I sent my rallye gauge cluster to Bob's speedometer to get them redone and then installed it and my gas gauge works now but my oil, temp, and batt don't. I installed new oil and temp sending units and made...

I've got a 74 road runner with a 318 and a 3.23 open diff rear end. I'm eventually gonna swap in a 408 stroker but I want to upgrade the suspension and rear first. I've been looking all over but can't find the answer to my basic question: If I buy a 8 3/4 open diff rear end, say with 3.55...

Hey guys, Last weekend I put new lifters in my 318 road runner because one seized up and was making noise. I got it all put back together and it started right up. Let it run for 20-30 mind and everything looked good, then I backed out of my driveway and then put it in drive and it killed. I...

My 318 was leaking a little from the valve cover so I decided to change it. I swapped it in and then started it up and it ran fine but starting spitting up even more oil than before. I'm sure the gasket wasn't on right so I took it off and then straightened it out. This time I bumped one of the...

How can I test to make sure my oil sending unit is working properly? I hook my dmm from the oil sender to ground and it reads open. I took it off and tested it and it still read open.

I have a 74 road runner with a 318 and I'm trying to figure out my temp and oil gauge. I disconnected the bulkhead from the engine bay side and noticed that the pins on the fire wall for both the oil gauge and temp gauge are continuous with each other (they are right next to each other). This...

74 Road runner 318 auto Ralley gauges. So about a month ago I sent my gauges in to bobs speedometer and he fixed and calibrated my who gauge cluster because my fuel temp oil and batt gauges werent working. I got it back and installed to and now my fuel gauge works and I havent hooked any...

I was driving my roadrunner today and i noticed that i was cruising at a steady 40 mph and i was pushing 3500 rpms. I have 3.23 gears with 24.5" tall tires. When I put my pedal to the floor, my tach said that i hit 8000 rpms???!!! Does this seem a little odd?

I was recommended to get a new wiring harness for the engine bay saying that my car would start better and be safer. I'm wondering if there is a way to measure how bad my wiring is, like can I measure the current or the risistance to see if I'm losing a noticable amount of power?

I just got my ignition system from fbo today and I'm trying to hook it up to my 318. My old ignition module had 5 pins coming from it and my new one only has four. Can I use the samewiring harness? Also its supposed to eliminate the use of a ballast resistor. How do I just take that out? Coil...

So i just started to reassemble my 318 engine after a top end rebuild and everything is finally assembled and I turn the key, It sounds like its turning over but i checked for spark and there wasnt any spark. I noticed the positive wire hooked up to the battery was really hot and glowed red when...
