Quick and Dirty Subframe Connectors for the Mopar A-body – 1967 Plymouth Valiant

Quick and Dirty Subframe Connectors for the Mopar A-body – 1967 Plymouth Valiant

So I’m building my little slant six Valiant to be a handlin’ machine and part of making that happen is a nice stiff chassis. Yes, it has a slant six, and I am putting subframe connectors into it. For a little more than $50 in materials I was able to buzz subframe connectors into the Valiant. It took two evenings by myself, might have only been one but I drank way more beer than... 

Mopar A-Body Torsion Bar Size and Part Number Reference

Here is a list of the different torsion bars for the Mopar A-body from 1964 through 1976. Included are the Mopar Performance part numbers (‘p’ part numbers) and where applicable, the OEM part number.

Slant Six Block Casting Numbers

The slant six engine was introduced in 1960 in two versions – 101 hp, 170 cu. in. and a 145 hp, 225 cu. in. From this modest beginning, the slant six built its reputation for performance and reliability. At the end of the ’69 production year the 170 slant six was dropped and a new 198 cu. in. version was introduced to replace it. At the end of 1974 this version too was dropped...

Mopar Alternator Upgrade

While at the junkyard, if the Mopar you are looking has the standard (not the 100 amp huge mother) alternator, grab that too, along with the plug, harness and voltage regulator. This gives you a much better voltage regulator and a dual field alternator (one field is constant output which works very well with the electronic ignition). Here is a wiring diagram for it:  Read More →

Chrysler Electronic Ignition Wiring Diagrams

Here are some useful schematics for the Chrysler Electronic Ignition system. When pulling parts at the junkyard you can use the Chrysler electronic ignition distributors from ’73 until the vacuum advance unit on the distributor disappears should work. Avoid anything from a “Lean Burn” setup completely. You will need to get the distributor, control module, ballast resistor...

Mopar Head Gasket Tech

Recently I stopped by to talk with Steve Carlson, another local Mopar guy. He had the top end pulled off the 440 in his ’69 Road Runner. I learned that the thicker composite FelPro gasket head gaskets lower the compression a half point over the original style steel shim head gaskets. Every B/RB engine built since its inception in 1958 came with steel shim head gaskets regardless of...
