I put a 1" spacer under my 750 mighty demon in my 67 Barracuda. I needed a new bracket to hold the cable. I got this All54225 which fits nice but now the Mopar throttle extension lever does not fit. The manufacturer website has nothing. I cannot find a stud that fits a 3/16 hole on the Holley...

If there is a way to easily get that info, i can check it quick. Otherwise, i don't know. This is the only other info on the website: Primary Discharge Nozzle Size (in.): 0.031 in. Secondary Discharge Nozzle Size (in.): 0.031 in.

I noticed a very distinct vibration in my car at 4000 RPM only. Below and above that, there is nothing. The car does not shake but the vibration is very noticeable. The vibration occurs when driving and parked, clutch in or clutch out. I have have had new motor in the car for about a year and...

Its 3.55. There are different types of sure grip?

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 dont suppose you can point them out in this picture? I am completely inept at wires.

It's that simple? No diodes or anything. Just connect both to red wire?

Nothing under the dash?

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...

Just the center link

I have the instructions from hedman. They are very good for clearance and what not. The installation just says to go through the bottom.

Is it possible to remove the steering rack and replace once headers are in position?

I am trying to install my new magnum 408 with Hedman long tube headers. car is a 67 barracuda, manual steering, manual brakes, manual trans. I have no clearance issues with them but i cannot get them installed. I tried putting the engine and trans in with the headers loose in the engine bay, no...

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

Does it have a hood at all? Does it have the bump on the front and does it look like a flat hood be used? Like the 67/68 hood

That will be the plan then. I will use the same pan and pickup so the location in relation to the bottom of the pan won't change.

Yes to HV and yes to stock oil pan?

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...

The kit I'm looking at uses H beams. What is the best way to check clearance? Actually assembling?

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.

Just so you guys are aware of what's going on. This engine is not going back stock. I have cnc prepped and milled 58 cc aluminum heads, roller rockers. In the process of selecting a bigger cam. I may go with a 408 rotating assembly as well. This build was not stock, is not going to be stock, and...

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...

Thank you. I wanted to be 100% sure before i bought a new one

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?

Your assumptions are correct. I may end up with a great 408 stroker. At the end of the day, the A-833 4-speed makes the car so enjoyable regardless of power. I have a set of 26 inch tall slicks that will work decent with the 3.55 gears. At the very least, for the 5.9, i would go with Edelbrock...

The 5.9 is out of car at the moment. No parts have been ordered so far. My build for the 440 alone is somewhere around the $10k to $12k mark. I have a 23 spline 4 speed. Ive been told that wont hold what i'm trying to build and neither will the rear end. Assuming they can survive, at the very...

How did you calculate the aluminum head at 11.5 SCR? I figured it would go from 9.0 to around 9.8.

These have the heat riser yet.
