Hey guys I've boosted a few Mopar engines but made log manifolds. I've seen a few guys reverse the factory manifolds around so they face forward. Can anyone tell me how they successfully joined the pipe to the factory manifolds without leaks. Welding a V-band to cast iron always runs the risk of...

Hey guys The 360 Magnum engines were never released in Australia so we have no listings over here for them. I Googled but found different heat ranges of 4 and 6. Can somebody please tell me what the factory spark plug recommendation is for a 360 Magnum 1994 model. I don't know what vehicle it's...

Hey guys I had a Magnum Pan gasket a long time ago and I seem to remember the rear end is a lot narrower than the LA rear gasket. Can I use the Magnum pan gasket with an LA sump. if anyone has a Magnum pan gasket available can they please tell me the thickness of the rear section on the Magnum...

Hey guys my flimsy factory transmission pan on my 727 always leaks. ID like a more rigid one like the cast alloy ones as they are much better. But the car is very low and I can't use those deep Pan ones. What is the shallowest rigid transmission pan I can get. Cheers

Hey guys I've got 360 pacemakers to suit in LA engine. I want to run them on my 360 Magnum that's running enginequest heads. I've checked out the difference in the ports and the LA extractors are much deeper and nearly come off the bottom of the Magnum head. They only touched by 1 to 2mm at the...

Hey guys I'm running a 360 Magnum in my old school charger. I am running a V2 vortech supercharger but it's super quiet. I'd like to hear it whine a bit more. I'm still running the Magnum Serpentine setup. I see the glimmer drive is available for the Chrysler la blocks but the pulleys are...

Hey all I have a a518 lock up converter I would like to use in my 727. My 727 is a lock up box too and they look identical. Even input shafts etc are identical. Are they interchangeable

Hey guys I was advised to get one of their turbos for my setup buy a friend. I have bought expensive brand name turbos in the past only to find out they are cheap copies and have failed. I have Googled and only found good reports about this brand. Has anyone had any experience using their stuff...

Hey guys I've engine swapped some magnums into old school cars. Are there any alternators with similar measurements I can use that are internally regulated and have a 1 wire activation. Thanks

Hey guys I have a 727 transmission that locks up automatically in 3rd gear. In the past I have run the 46rh / A518 transmissions which you have to supply power and an earth to get them to lock up via a solenoid. However this one just locks up on its own and only in Top gear. Does anyone know if...

Hey all I'm after the front and rear valley cover seals for my 360 magnum as I already have intake gaskets. Does anyone know if I can buy them separately or are the la ones the same.

Hey guys over the years I've installed several rear main seals on my magnum engines and some have leaked which is annoying on a brand new engine. I used to just put Loctite in the groove and then press the seal in but this has leaked several times for me. The last one I did I placed a generous...

Hey guys I'm rebuilding my 360 stroked to 408 turbo magnum. It has around 800hp at the crank. I will be spinning it to around 6500 RPM. Just wondering what main bearings people are running in the bigger horsepower engines. I have read that half groove bearings are better to take the extra hp...

Hey guys I'm running a solid cam with quite heavy spring pressures in my 360 magnum. My timing Mark jumps around quite a bit and I'm guessing it's due to the feed back from the spring pressures and timing chain is not tensioned as it never did it when I ran a hydraulic cam. Does anyone know...

Hey all I'm changing my motor to an internal balance motor and need to buy another flexplate. I'm running a powerglide on the back of my Mopar small block. Thais all came as a kit. It's some sort of Chevy plate can anyone tell me what it is or where I can buy one please.

Hey all I have a small block magnum that has had bad oil pressure for years. I put in a mellings high volume oil pump a couple of years ago but it didn't help. If I run fully synthetic engine oil I have around 10 PSI at idle. It does go up as the RPM goes up and I stripped the engine down in the...

G'day all I'm currently rebuilding my engine and considering fitting a girdle. I've never used one before and the only reason I'm considering putting one in now is because I read on Google that girdles are good for stroked engines. I'm guessing stroked engines produce more torque which means...

Hey guys My son has brought himself an Australian Mopar and wants me to build him and engine that will give him around 800 at the tires so I'm guessing I'll be pushing high 900s at the flywheel. I have built engines up to 650 at the wheels so only 150 HP short of the goal. I have used a magnum...

Hey guys I'm looking for some good quality forged pistons for my 360 magnum that will handle 800 horsepower at the flywheel. Preferably standard 4 inch bore if possible. Needs to be at least 20cc dish to get my compression down. Thanks

Hey guys I've been running a turbo magnum engine for a couple of years now. I have a high and low boost setting on 420hp and 650hp at wheels. I've been running a standard magnum bottom end and the only thing that seems to let go are the pistons. So I'm putting a set of forged pistons in but not...

Hey guys I've got a stock 5.9 magnum bottom end. I've been running a turbo for a couple of years and a piston has finally let go. I want to replace the pistons with forged ones with low enough comp to suit the turbo. Can anyone suggest some pistons or what company I should talk to. I'm in...

Hey guys I know some of the LA engines have a metal oil Slinger but I've noticed the Magnums dont run one. In my rebuild kits I noticed that there is a felt looking Circle which I'm not sure where it goes. Any ideas

Hey guys I've been cleaning up some factory 5.9 magnum pistons with oven cleaner. I've done in the past without any problems but this time I left them a bit long. the oven cleaner discoloured the pistons a little bit. if they coated pistons then I'll replace them but if they're not coated I'll...

Hey guys I'm just stripping down my Magnum engine as I think I've broken a ring landing on the piston. I'm still running the standard Magnum pistons. Is there a forged option that I can use on the factory rods that won't break the piggy bank

Hey all I run Mickey Thompson's SS on the street but they wear out so quickly. Is there some other options that will give me decent grip but last longer than the MTs I currently run 15x8 rims but Im happy to buy new different size rims

Hey everyone I have built my fourth Magnum engine and with all 4 of them they all leak oil out of the front timing case crank seal where the balancer goes in. I have replaced the front seal several times but they all leak. I noticed the magnum engine doesn't have an oil slinger on the crank...

Hey guys Has anyone used the MLS cometic magnum head gaskets on a magnum engine with a high lift cam. I want to replace them but I'm currently got LA style ones. The LA style ones don't have gasket around the pushrods where the magnum ones do. I seem to remember having to trim the magnum...
