You may want to google and research the Holley Sniper EFI conversion. This may not be an issue specific to the Challenger, and it's possible others have run in to this same problem and posted their fixes. Your audience is somewhat limited, here, to mopar-specific topics.
Over the years, this has been tested more than once. I seem to recall the conclusion was as @Challenger RTA suggests, the scoops are too low, within the turbulent slipstream along the surface for there to be any real passive benefit to opening those up.
We're talking about passive cooling and...
If you're going for an ideal, you'll want to use a break-in oil, with the zinc already blended into the oil.
Some sources suggest adding the zinc (such as ZDDP additive) to standard motor oil does not protect the camshaft on initial startup as well as the pre-blended (with zinc) break-in oils...
I've had experiences wear one short causes another. This happens when the first wire heats up inside a wire harness and melts the insulation of adjacent wires causing additional shorts. More than once, have I found myself scratching my head why I have a short on something I have not...
I do not know where the image in post #3 came from, but it seems a standard reinterpretation of the manual. The 1970-71 Parts manual is a bit vague on this, in my opinion - perhaps even in error, by some accounts.
In my observational experience, the Shaker Hood hinge spring on Barracudas/Cudas...
I encourage you to start a new post, and not hijack an older one. You deserve all the help you can get, and you deserve your own post on this topic. I am now researching your question, and I will be happy to post my reply into your new thread.
Just order a replacement windshield from one of those mobile windshield businesses. If you're like, I tend to overthink things. I'm not convinced these measurements are anything you need to worry about, if you pay for install. Install is often free with the cost of the windshield. If the...
I seek out and enjoy most things, Carter carburetor-related.
Can you give us a little more to go on? Which year? Which engine? Help me visualize the setup, and I can better provide the data you seek.
I'm happy to help, but right now, I've got more questions than answers. Sorry.
Hello from Santa Rosa, CA. A long-time Mopar lover, myself. Very nice car, well done. What a blessing. I hope to see her someday, as you live nearby. Best regards to you and your project.
Those prices seem reasonable. Learning how to do some of the work, yourself, particularly, weighing/measuring and validating work done on parts, is well worth the investment in tools and time to learn.
But if you just want to simply pay someone (presuming competent) to "git er done" without...
If I were starting from scratch, and faced with building a sweet stroker SB compared to (the lesser performing Big Block) 383, my biggest concern would be making everything work together, and work right, to produce a nicely performing car.
Going factory (or slightly better than factory) has...
a sticky tumbler may cause this. one or more tumblers actuated and pushed further than usual when using a different key can cause it to stick, thereby jamming the key.
as stated above, all the Chrysler keys of this era would normally slide in and out. If it’s a different model key, and it’s...
I seek a crummy-yet-restorable or even nice condition single road lamp for a survivor 1970 'Cuda. I'm prepared to buy a set of two, if needs be. Ideally, the lamp housing would include the nut on the bolt, wiring from the bulb to the harness, not horribly corroded outer chrome ring with...
