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 Road Runner with rallye gauges and the brake warning light is just hanging out behind the dash not plugged into any socket. Where is supposed to be plugged into? I don't see a spot for it? Mine also has a blue rubber sleeve over the brake warning bulb, is that factory?

I have a 74 Road Runner and I only have 10V to the starter relay coil when the key is in start position (which isn't enough to trigger the relay). I traced it back and it looks like this connector is probably my issue. It's burnt up and melted. I found the ignition switch harness with the...

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 have a 74 Road runner that currently has 205/70/r14 and 245/60r14 tires on crager wheels. The tires are getting old and they also look tiny in the wheel well so I want to upgrade to something bigger. When I bought the car it came with a set of 15" rallye wheels (perhaps original?) that I'm...

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 called up both Crane and Comp today to see what their recommendations were for a cam for my 5.9 build. Stock bottom end, stock heads, air gap intake, headers, dual exhaust, FBO ignition, and an eddy 1406 carb 600 cfm (might upgrade this), 3.23 gears, street strip use. I want the long snout...

I'm looking at a 742 case, but want to confirm the sure grip type. Is this a clutch or cone sure grip? https://photos.app.goo.gl/5hcXJCjirXAHDQcZ6

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 am working on getting my heat working when I realized my mom stock heater control valve was all seized up. I ordered a new 4 seasons heater control valve but realized that there must be another bracket to mount it to the fender using the factory holes. Is this the bracket that I need? I wasnt...

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...

I've had to replace my rubber fuel line hose twice in the last 3 years. I've just been getting the regular NAPA fuel hose but it keeps cracking and I don't want to play this game anymore. Other than going to hard lines, what are some fuel hoses that will last longer yet still look somewhat...

I have a 74 Road Runner with a 318 and an auto in it. The previous owner put an Edelbrock 1406 600 cfm 4 bbl carb in it with a performer intake and I've been told that It doesn't have the correct linkage or bracket. They say I still have the 2 bbl hardware on it. Can anyone tell me what hardware...

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...
