Took the third member out of my 8 3/4. I understand the case is a 741 but i'm not sure what the LSD is. It does not look like sure-grip units i see online. Can anyone identify what brand/type it is? The whole setup is behind a 500 ft-lb 408.

I am trying to wire a 6 AL box into my 67 barracuda. I tried to wire it to an open fuse, like a tachometer, but those 12v sources turn off when cranking. I know everything works because i wired the small red wire directly to the battery to test it. Does anyone know of a keyed 12v source that...

Trying to learn more about my 4-speed. I have Passon's book but im still not finding too much. The tail shaft is stamped "C39126-3" or "C99126-3". The book says the 99126 was used from 69 to 71. The car its in is a 67 barracuda and the car it is believed to come out of is a 72 duster. What does...

I'm installing a hydraulic roller Howard cam in my 408. It is a 5.9 magnum block. I understand that the thrust plate is the only thing controlling end play? Does the plug in the rear of the block need to be set somehow? Do i need shims? Or do i simply reassemble? Thanks

I have done a bit of research and have seen many different opinions. I am building a 408 stroker 10.6:1 compression. 241/247 @50 cam. Scat forged crank, Molnar H beam rods, icon dish pistons, stud girdle. CNC prepped eddy RPM heads. My question is if i need a HV oil pump and if i can use it...

I'm looking into a 408 stroker kit from Hughes engine. It is a scat rotating assembly, icon pistons. Has anyone had any experience putting one of these in a 5.9 magnum? I want to know if anything need to be modified such as block matching (other than the overbore), oil pump/pickup, or the oil pan.

5.9 magnum 360/380 crate engine. On my M1 single plane intake there are two sensors in the coolant passages. Then top photo sensor had two terminals but one broke off. I need to replace it but can't find it in a parts lookup. I have an electric fan on the radiator. Can anyone identify this...

The pictures above are from my 5.9 magnum. It is a 360/380 crate engine. I am upgrading the cam in this engine. Is this a magnum cam or an LA cam? If i order a new magnum cam and timing gears for a magnum will this all go back together and work, specifically with regards to the manual fuel pump?

These came off of the 5.9 magnum in my 67 Barracuda. I have seen these exact manifolds on my great uncle's 340 T/A. So what exactly are they and were they offered on a bodies? What is the resale price of these?

Im trying to remove the speedo cable from the trans. I have removed the holding bracket and bolt. Should it just pull out from here or is there another step?

Do any models of these cars exist in 1:24 or bigger? I have some 68 notch but they are small hot wheels ones.

First off, sorry if this is in the wrong section. I have purchased a 4006630-440-8 stock 440 engine. I am seriously debating on putting this engine in my barracuda with TTI headers. It has manual brakes and steering so I'm not worried about losing those. To make it worth it to me, I would want...

I just installed the MBM small bolt pattern disc brake kit on my 8 3/4. I have 15in Rallye wheels but they hit the caliper in a way that even grinding a little bit would not help. Do these wheel not fit with the kit or did I do something wrong?
