The truck needed a new radiator but when I went to order one they were on backorder so having a brand new aluminum one laying around I used it.. but no trans...

    512 builds.. post em if you got em!

    I've been thinking long and hard about getting more ponies under the hood of my Charger, boost, cubes, etc and am leaning towards a 512 low deck. Reasoning, any form of boost snowballs $$$$, complete fuel delivery overhaul, expensive carbs, turbos or superchargers$$$, waste gates, plumbing...

    Need some 5.9 diesel help.

    My brother has been asking me to help him adjust the valves on his 07 24 valve Cummins and I'm clueless on these. The valve adjusting itself is a no brainer but I can't find a timing mark anywhere? How in the hell do you know where to put the engine to adjust it?

    Rod and Piston options for boosted 451

    Some of you may be familiar with my build but those who aren't it's a mild 400 with a 440 rotating assembly. I've been seriously considering adding a centrifugal supercharger to it so am looking for piston and rod options. Currently it has the complete rotating assembly from a 1971 440 (forged...

    How to identify rear axles? 72 Satty

    Forgive me fellas but I've been blessed with only 8 3/4's until now and need to know what I have. I recently purchased a 72 Satty that had a badly broken tailshaft housing (727), after swapping it I realized the driveshaft seemed very long.... might be what broke the tailshaft housing? Anyways...

    Fuel pump..... again!!!

    Just looking around for options after having an embarrassing weekend when yet another fuel pump took a crap in the mall parking lot! Originally when I built this car I installed a Holley mech fuel pump, it lasted 2 years before it would no longer keep up at higher rpm's so I tried a Carter which...

    Winter mix fuel, anybody know the diff?

    I've got a couple new problems with the charger:BangHead:. It's now stalling directly after it fires once it's been fully warmed up like after filling up for gas. It started doing this at the very end of fall, with a nice weekend here in Ohio I took it out for fresh fuel and to run it for a bit...

    More fuel related issues, now the pump!

    Well fellas I feel like I've finally zeroed in on my setup to where everything is in harmony or at least until this issue popped up.:BangHead: I just wanted to pick your brain on fuel delivery mostly the pump. I have an issue, I'm running out of fuel during full throttle runs where I'm hammering...

    choke or no choke?

    I've been talking to FBO about having them tune and ship me a new Quick Fuel but his recommendation comes without a choke horn? I'm obviously worried about not having a choke in Ohio and think I might be better off with it and wanted to hear from those who get away with it or condemn the idea...

    Thinking about a Quick Fuel??

    Since completing my Charger I've been doing allot of tinkering with carberation, started with an 870 Avenger which worked great but liking double pumpers I switched to a Street Demon 850 DP and really like it. The problem is the idle circuit, any adjustment that equals a good idle and off idle...

    Header vs Ground clearance?

    Any recommendations for a shorty header? I'm planning on replacing my headers this winter with something that will provide way more ground clearance and preferably stainless as well. I'm running Hooker Super Comps right now and like them but given the fact that I have a 400BB (3/4" lower) and a...

    Safe RPM for a 451" range????

    I've been playing a bit to much with my Charger and get into the rev limiter way to often so what's a safe RPM range to twist it up to? It's a 456", cam rpm range of 1,800-5,800 rpm, forged crank, rods have been resized and floated, KB Hyp pistons, all ARP fasteners and the rotating assembly has...

    Why universal joint angles are important (video)

    Threw my headaches of trying to eliminate a vibration I've heard so many time "it's not the driveshaft angles, look elsewhere"! I came across this cool little illustration that does a wonderful job of showing what is so hard to put into words so hopefully this will shine some light on the...

    The vibration that won't quit, what's next???????????

    Man I'm at wits end with this vibration, I've checked everything that I can think of and replaced or addressed mostly everything. It's a very odd vibration, from 0 - 55 mph it's smooth as butter but once you exceed that and go into a coast like cresting a hill or just push in the clutch it...

    Rebuilding an 8 3/4 489 sure grip differential

    Since I like doing things myself I thought I'd start a thread showing how to put an 8 3/4 pig together in hopes that others will see that it doesn't take a rocket scientist to do it. One big problem........... I don't know how to do it haha, for that reason I'm calling on the help of the more...

    8 3/4 ring and pinion setup opinions

    I just bought all the stuff to build my 489 pig and have been reading up to make it go as smooth as possible and wanted to pick your brains for pointers. I purchased a set of Richmond 4:30s, a Richmond rebuild kit and the crush sleeve eliminater. I remember I think it was Cranky mentioning...

    Pinion angles

    I've been trying to track down a high speed vibration in my Charger that's been there from day. Because it runs perfectly until you get over 80 mph hour (mostly after letting up) I've put it off in hopes that the tranny swap with the new shaft would cure it but it persist. I pretty sure I've got...

    New one piece windage tray - gasket

    I had a thread not to long ago asking about what the best pan gasket was since I had an annoying leak to fix and took the advice of upgrading to a windage tray while I was at it. Anyways here it is, I've put a couple hundred miles on it without a drop (I did add a little RTV at the timing chain...

    Technoligy is a wonderful thing........Check this out

    Since I still have an annoying high speed vibration (80+ mph) even after just finishing the Viper tranny install (new driveshaft) I decided to start researching driveshaft angles which led me to this. http://www.tremec.com/menu.php?m=154 It's a sweet app for your smart phone that turns your...

    suggestions

    Sorry for yet another carb question but I'm against the wall with time tonight with the Charger being the only car I have to haul my kids around in for the next couple of days. I've been tinkering with the new Demon 850 and have the running really well accept for a low rpm miss. It runs perfect...
