It's a Hughes hydraulic roller cam. I'll have to find the cam card, it's been awhile. But it's something like [email protected] and .570 lift. I had a smaller hughes cam with the 360/EQ heads at first, I think it was a [email protected] and .540 lift. It went 12.90s. The car was a little lighter then with some...

I have a set on my Magnum 408. Mild cam, pump gas, 3350 pound Dart, 3.55 gears and it runs 11.55 @114. No porting or anything fancy, it's a garage built street car. No Dyno sheets or anything unfortunately. I had EQ heads on a 360 Magnum in the same car. It ran 12.60s. Same cam, similar...

My 408 had some noticeable blowby when I first fired it up. It was all fine within the first few test drives. Rings take time to seat and seal properly. Almost like they have to break in..... I wouldn't be too worried about it. But I would tear it down and inspect it just for peace of mind and...

How usable can one of those engine be in a streetcar? The power has to come in REALLY high up I think.

Drop in a good used 5.9 magnum. Use a magnum bolt pattern intake or have the magnum heads redrilled to LA pattern. Headers, good 2.5 inch dual exhaust and a decent tune up. Itll run great and be north of 300HP for cheap! I've bought a few 5.9 engines in great running condition for $600. Your 360...

Hey guys, I'm looking for ideas on mounting the coil on my small block. I have a 408 magnum in my 70 dart. I had an edelbrock dual plane intake on it and I had made a bracket to mount the coil on the back of the intake right next to the distributor. I am swapping to a single plane M1 intake...

I have read several things about the EFI not working too well with a dual plane. That said, there are a bunch of people using dual planes and EFI and loving it.

I have a magnum based 408 in my dart. I'm hoping to start installing my Holley Sniper EFI pretty soon. It's an 11:1 compression engine with some edelbrock magnum aluminum heads. The cam is a Hughes engines .571/.576 lift and 234/238 @.050. It's a street/strip car, never gets used for daily...

A converter will usually have a few weights around the outside edge used to balance the converter. My stock 360 converter did. But a 360 and some 5.9 magnum balanced converters will have a weight welded to the flexplate mating side. THAT one needs to be removed to make it a neutral balance. The...

I'm going to do just that. Tap the rear of the intake and put my heater core hose there. Then I'll put the sensor in to replace the coolant hose fitting. Thanks for the idea, I hope it works.

I didn't even think about that. That's a good idea! I wonder how accurate it would be?

I do have an electric fan. I "temporarily" wired it two years ago with a relay to run when the key is on. The holley EFI has a built in fan trigger that I'm pretty excited about. I have thought about just drilling the intake and I have the proper tap and bit. But I'm afraid of it cracking like...

They have plenty of choices for chevrolets. Those will also work with 1978 and older mopar. But I didn't see one listed for the smaller 1978 and up mopar. I thought about a T fitting. But I wasn't sure how accurate it would be since there wouldn't be any flow across the sensors.

There isn't much if any extra room to put it on the bypass with the magnum serpentine setup. The A/C compressor is mounted right above it. The bracket is notched to make room for the hose and clamp.

I ordered a Holley Sniper EFI to put on my magnum based 408. The street demon carb has treated me well but I've had the itch for an EFI conversion for awhile. I'm currently running an Air Gap intake on the engine with all of the factory magnum accessories. The two coolant ports are being used...

The 95 and older A518 will be an RH AKA 46RH. 4 speeds, rear drive, hydraulic operation. I think 96 was the change to the RE A518 AKA the 46RE. The 46RH is the one you want if your going with a carb. The 46RE needs the ECU to operate. Unless someone has come out with a trans controller for it...

That is exactly how I do it. Works great. I put a 90 degree after on my 360 and had nothing but issues. I was priming the engine on the stand and the sealing washer on the bolt blew out. It shot a stream of oil 10 feet away. That was a mopar gasket set. I bought some "improved" gaskets and had...

I've always put rope in the cylinder and spun the crank until the piston stopped. No worries of losing the valve that way and you can hit the retainer as hard as needed without the valve moving.

I believe the same tool works for both big and small block chrysler. I was able to buy priming tools for ford and chevy locally but as always, nothing for Mopar!

My dart had sat for nearly 20 years when I got it. I pulled the plugs and cranked it over for about a minute and to prime the oil. That engine ran great for several years and thousands of miles. But, I had plans to replace it anyway so I didn't care much if it hurt it. I think that pulling the...

I always smear a thin coat of RTV around the water ports on my intake gaskets. Both sides of the gasket. I had a bad leak there when I swapped my OE magnum intake for my edelbrock intake. I replaced the cheap gaskets with some “premium” fel-pros and still had a leak. RTV cured the leak for good...

I would think the trick flows mimic the LA head. I've heard that guys have to modify and shim LA accessories and brackets to fit on magnum heads.

Also have edelbrock heads with the OE magnum serpentine setup. No issues except the OE brackets cover up a bunch of the pretty machined aluminum!

Those were the OE installed gaskets. My grandpa bought the truck new. The intake is an edelbrock dual plane for the magnum engine, carb was a demon 625. The engine was running great... until the gasket popped. Parts fail, stuff happens.

My magnum did the same thing! Smoking from the exhaust and blowing smoke out of the breather. It ended up only being a failed headgasket. The compression was leaking into the crankcase and blowing smoke out under throttle. And on decel it was pulling oil into the cylinder and smoking from the...

I did the exact same thing as you, OP. I drove my car and knew it was way down on power. Ended up snapping off and intake valve and destroying a piston, bent some rods, scored the cylinder wall, tore up my new edelbrock heads, etc. I had built the engine myself and it ran great, went 12.80's in...

Magnums are the same location as LA blocks. I would check the oil filter also. I've partially filled a filter, lubed the gasket and installed a filter on my dart only to realize that the gasket had fallen off and was laying in the ground!

Been there, done that... I’ve got a destroyed short block to show for it!

My friend had a block that looked just like that one. The machine shop media blasted it, tanked it, bored/honed it, honed the lifter bores, decked it, etc and it turned out great. It won't cost much extra, I think he paid $100 for the media blast. Everything else it needs is pretty standard in a...

Go forged, it's only a couple hundreds dollars more for safety and peace of mind. Summit will price match! I saved nearly $200 by shopping around and having summit price match on my 408 forged scat kit.
