Tech Q & A

I’ve seena design on some oldChrysler parts boxes (seebelow). What does it standfor? It is read D-P-C-P-D,and simply means “Dodge,Plymouth, Chrysler, DeSotoparts”. It was used officially onretail boxes from 1933-’36 only,but continued…

In your huge libraryof illustrations and graphics,I’m wondering ifyou might have details andmeasurements for the hood/roof/trunk lidstripes for a ’66 Barracuda.I assume they were painted on(rather than decals, correct?) Iwant to paint…

Can I change the bulbs behind the typical A‑body dash panel (mine’s a ’69 Barracuda) to obtain brighter gauges at night? How many watts are the original bulbs (GE158) and what can I use to replace them without melting the surrounding…

I read your Hemi crate article, and was duly impressed that Barton was the new vendor. Since I am in the process of building a Hemi, I figured if Barton and Mopar Action had a formula, I could follow it and maybe add a couple upgrades like…

I recently removed my slant-six to put a 361 B-engine in my 4-door ’65 Coronet with a 4-speed using a Lakewood scattershield. I am having a lot of issues with the starter shifting out of alignment and not reaching the flywheel. Are there…

What’s the best way to flush a cooling system at home? In my case, I’m not talking a system that looks like a chocolate shake, just something that’s been neglected in recent years. Engine is a stock ’77 440 in my ’73 Satellite wagon. I…

I recently bought a basket case ’68 Charger. I have been putting it back together with the help of my friends Allen Brady and Scott Zimmerman; without these two guys this car would be years sitting while I figure out where all the pieces…

I have a ’73 RR with a 383/727 combo that was rebuilt recently by a local Mopar guy. Honestly, the thing runs great—12.90s @ 108 with 3.23s in the rear, but the fuel economy absolutely sucks, like 7.5 mpg. Of course I never expected this…

I rebuilt my ’70 T/A’s 340 Six-Pack engine a while ago, and it’s never run right. Everything is stock, except the cam is a purple shaft 0.484˝/284°. I've put about 2000 unhappy miles on the thing thus far. The carbs were rebuilt, but the…

I’m building a 273 from a ’66 Coronet to swap into a ’64 Dart convert. I’m using very slightly worked 302 casting heads from an ’87 318. I have a factory 1967 273 4-Bbl intake. It has the standard smallblock intake bolt angle, so it will…
