Max cam on a stock 5.9l Magnum
What is the max cam lift and duration I can run on a stock Magnum 5.9l?
|
When you say can? Am I correct in assuming you want to leave the heads alone? With stock springs the 5.9L truck cam is max. The springs suck. Even with the truck cam, which is the 300HP Crate motor cam, the OE springs will float around 5000 rpm.
The 380HP Magnum crate had 230/236 .501. The low lift was due to the retainer to guide clearance. .512 to .520 is the upper level of lift and I always check the clearance!!! The machining was not very consistent. |

Can I use 5.2 magnum heads ? |
A worn out roller cam? Wow..
I have a couple 5.9L truck OE cams in the garage ( maybe even a Comp one or two around here also) and I know I have some drop in Hughes 1110 springs... PM me if interested. Im building a 408 and used a 1998 2500 entire engine as a donor so the parts, rods, cranks, cam etc... need to go. |
Are you quite sure it is a Magnum motor and Not an LA... Roller cams should last 3-400 K miles
318/360 magnum heads are the same |

No engine will survive with no oil...

Still looking into which route to take now... The guy that has my motor was basically cutting me a great deal on swapping short blocks. He had a low mileage magnum motor that had no top end and he was going to put my top end and accessories onto his motor charge me less than it costs for a complete bearing/ring rebuild kit. Now I am looking at having to buy a complete top end to finish the project. Looking online I can find complete head sets for anywhere from 500-1500 depending on how "built" they are but I can find complete lower mileage 5.9 Magnum's in the same price range. I imagine I will suck it up, find the money, buy some heads and a cam, and finish the motor out... just have to wait longer on buying the rest of the items needed to actually swap it in.
