I am helping a friend get his '66 Belvidere tuned up. I am trying to find Autolite 84 spark plugs, and no one seems to have them anymore. The engine is a steel-headed 440. Any suggestions on a good replacement? Thanks in advance.

I recently purchased a Jones/Moroso Mechanical Tach for our N/SS car. I already have the distributor, but am really struggling to find a 6 foot long cable that has the square, female end for the tach as well as the Mopar ignition end on the other side. I saw an older post in the archives...

Good day. My '69 RR uses a Mopar Performance distributor and a chrome ECU box. Had it on the car for years. RB based 496 inch engine runs mid-to-low 11's. Lately I've been burning up rotors. The car won't pull past 116 MPH. It used to turn 122 MPH. I noticed Mancini and others offer...

We have run an Optima Battery in our '63 Max Wedge Plymouth for years. In fact, originally we ran a red top, and currently a yellow top. The car is 12.2:1 compression. The yellow top we currently run seems to need a charge after every pass. The battery will bleed down to 25% life after a...

I'm working on an old, Chrysler dual point distributor. It's been in our '64 Fury Convertible street car for some time. I want to replace the points, condenser, cap, and rotor. I've never worked with points in the past. Can you tell me what the gap should be? I've heard a number of...

This thread is not to thrash a vendor, but rather to see if others have the same issue, and hopefully to prevent someone else from having the same problem. We had a pair of 8 3//4" Yukon Axles in our '69 Road Runner. Two weeks ago my son broke one in half at the starting line. When removed...

Last Saturday, my 17-year old son raced my Road Runner, street car at Cecil. It was his second time competing in an actual race. We headed to Cecil Co and he double entered. He ran 11.50 Index as well as Pro Dial. Both classes ran a .500 Pro Tree, which he had never run before. We had a...

Thought this might be an interesting thread. I am putting a '64 Fury together for my son. It's a 'vert. I've been looking for photos of similar cars for fun. Anyone have some good pics of convertibles doing their thing? This one's a 440-4 speed. Street/Strip.

OK...been tracking a high end miss on FRUSTRATION's 426 MW engine. We run a MSD Pro Billet Distributor with an MSD 6AL. I run Autolite R72 plugs gapped to .035 and 38 degrees of timing that's locked in. We've run this combo for more than 20 years with no real issues. Last year the car...

I recently found a pair of polished Super Tricks in 15 x 10". I'm planning to put 29.5 x 9 x 15" MT Bias Ply Slicks on them. My question is... What will the overall width of the tire be like moving from a 10" wheel to an 8" wheel. With the 8", the tire has a pretty good bulge in the...

I am planning to run my 69 Road Runner in a bracket series this summer. The car has gone as fast as 11.07 on it's only track time with the new combo. I do not have a roll bar, but would like to run it at a dial in of 11.50 or slower. Is it ok to unplug the outboard vacuum lines in order to...

So I've been a drag race fan, spectator, and racer my entire life. I'm almost 50. My Dad used to take my brother and me to the E-town Winston Championship Series (WCS) points meet once per year. I've always been a Cragar SS fan as my grandfather had them on the '69 Road Runner (that's now...

I recently installed an RB-based 496" engine in my 3800# road runner. It's a 440 Source kit with CNC ported Stealth Heads and a six pack induction. I also run a small solid roller cam with .575 lift and 262 @.050 duration. I have a 3800 RPM 10" converter and 4.30 gears. I drive the car on...

Hello. I purchased a pair of AMD stamped steel valve covers for my RB build. had them professionally painted, then found out the baffles under the oil fill hole and PCV valve hole hit my adjustable rockers. They've been sitting in storage since. I have about $280 into them, and want to use...
