All set. Unhooked the ballast resister and placed a jumper wire between the wires leading in and out of the resister.

Solved. Discovered the fuel pump was leaking and probably leaking back. Replaced and starts right up. Also can now run after market air without the rpm being drawn down to a stall.

Cold starting on my stock 1974 Roadrunner is a little hard. Have upgraded with new plugs, wires, coil, and the HEI distributer, as well as a brand new 2 barrel carberuter. After sitting overnight ( and this is not new) it needs to crank over numerous times before it will start. After it does...

I am upgrading my 1974 Roadrunner with a 318 engine with a new HEI Distributer, new coil, and wires. Only instructions are DO NOT USE THIS WITH A BALLAST RESISTER. As we all know 74,s have a resister. Instruction state to attach the red and black wire from new distributer to the coil. So my...

Is it called something else? Say an idle control valve or mayby a carburetor solenoid valve. Looking into getting one but want to get the correct part. Any more info would be a great help. Thanks.

HELP. I have a 1974 Roadrunner with a 318 engine. Originally an automatic NON air-condition car. Currently it is a 4 speed and has after market air. My problem is when i turn the AC on it draws the rpm down and sometimes even enough to stall. Have checked for Vacuum leaks, replaced the vacuum...

Have not checked the timing but will get that done. Tks.

I do know the engine has an aggressive cam. It is a 318. Will have to check on the EGR valve.

Recently i had my 1974 roadrunner transmission completely rebuilt. Everything new. Original gears were 2.66, 1.91, 1.57, 1.1. New gears are 3.09, 1.57, 1.1, .73.1. What i am noticing now is in 2,3 or 4th gear when i let off the gas and start slowing down i start getting a "jerking" motion in the...

Fixed. Took it off and sprayed a ton of cleaner in the mechanism. Must have been gummer up. Works great now.

Thanks for the bit of wisdom. Will check it out. I know i show as Florida, but am a lifelong resident of East Bloomfield.

My 1974 Roadrunners emergency brake will not "catch" if you will when i press the pedal. Not a big issue except it is a standard. Anyone had this happen before? If so is there an adjustment or is a new one in order?

Come to find out, it is only 19 inches. Yes the opening is 22 inches so i am investigating getting a 22 inch.

Can anyone tell me how many cores a 1974 Roadrunner have. My radiator # 3692934 which is the original radiator on my 318. Since i bought the car i installed vintage air on it runs pretty warm in the summer so looking to upgrade to a 3 core. Thanks.

Anyone have an a833 4 speed transmission that utilizes 4th gear as an overdrive. Currently having my 1974 roadrunner with a 318 tranny being rebuilt. It runs high rpm in 4th and thinking of going to overdrive. Any thoughts and comments are appreciated. Thank.

Hello all. I have a 1974 roadrunner 318 4 speed. The original owner put a larger agressive cam in the car. Can anyone tell me what the original 318 cam would have been as i am looking to have the engine rebuilt back to original.

Try hiltop auto parts. They have a ton of NOS items.

So i am having some shifter vibration as well as what sounds like a little humming from transmission. I also am thinking of having thr transmission overhauled and changing the gears and making it an overdrive but looking for opinions on good ratios. The transmission was built in 1969 and is now...

I recently had vintage air in stalled on my 1974 roadrunner with a 318 engine. The car almost stalls or sometimes does stall at a traffic light as it draws down the rpms. Anyone have any reason why?

Mistake on my part. The carb is a 600 not 650 and not a DP. The carb that was on it was a DP 750. I also have the original carb which was a 2 barrel. Tks. for t It has the original dual exhaust manifolds, so no headers. Not sure how aggressive the cam is but here is but here is a photo of the...
