 OP pro stock Joined: Jul 2005 Posts: 1,499 Slidell, LA | How hard is this really? I have a 440 and am thinking of going up a little more on my cam like to a Comp Magnum 270. I currently have a Comp HE 268 with Comp springs so the heads should be fine. What are the steps I need to have? What practice I need to wait out for? What has and has not worked well for you if you did this? Other than making sure #ane is at TDC and the timing marks are aligned, what else should I exercise to make sure the new cam's orientation is correct? Thanks Guys! 70 Challenger, 440, 4-speed, pLuM cRaZy |

All you need is plenty room to get the cams in and out. If you lot degree in your new cam, you may demand to knock the motor mounts loose so you can jack the engine up enough for the caste wheel to clear the K member. |

Only I had AC and had to remove the condenser to put in the cam. At a minimum, yous will put all front accessories, the radiator, the fan and shroud and perchance the condenser if you lot have one. They say there are no such thing as a stupid question. |

I had to pull the radiator, A/C condenser, and hood latch support in add-on to the aforementioned accessories. It's do-able for sure. TBH the hardest part is the oil pan as yous have to jack the motor upwards and pull the center link to work that pan/tray off the pickup tube. The best part is with all that stuff off, yous can stand inside the engine compartment with the motor and work on it. :-) FWIW I degreed my cam and information technology ended upwards having to get in 2* retarded to get the cam installed to spec. If I had lined upward the dots I would have been slightly advanced which some would say is better but this was a custom cam and I was instructed to install per spec. Some have said they have been equally far as 6* out of spec so might be worth information technology for whatever blazon of functioning build so you know the specs yous are at instead of guessing. |

The cam is 180 degrees out on every other engine rotation. It kinda spins at half the crank speed. At present the distributor can exist troublesome at 180 degrees out. We are brothers and sisters doing time on the planet for better or worse. I'll have the better, if you don't mind. |

There's lots of room in forepart but all that does is push yous farther away from what you want to access. We are brothers and sisters doing time on the planet for better or worse.

I also used a lifter extractor to remove the lifters without removing the intake manifold. That saved some time too. Be sure to put on a fresh loftier quality timing set, and soak the chain in some loftier quality synthetic gear oil overnight. I use that stuff in my chain saws for bar/concatenation oil, and it works better than anything else I've ever tried to more than double chain life. My timing chains sseem to develope significantly less stretch when I pre-soak them with the stuff besides. 1970 Plymouth 'Cuda #'s 440-half dozen(block in storage)currently 493" half-dozen pack, Shaker, 5 speed Passon, 4.10'south |

| I Alive Hither Joined: Jan 2003 Posts: sixteen,375 | To the OP: Cab is correct, that cam swap volition cyberspace you nothing and probably set you back. Swapping from an XE268 to a Magnum 270 y'all go on the same intake duration at 0.050 lift, 224degrees, and give up lift by a hair, 0.007" intake and 0.010" exhaust. Both the cams have generic "chevy" lobes which don't accept advantage of the larger Mopar lifter. The XE series, however, is at least 10 years and probably 20 years newer in design than the Magnum series. That means that the XE268 will accept more area under the curve and outperform the 270 Magnum except if the engine is already overcammed. The XE___HL line Cab mentioned are newer than even the XE series and designed with the faster lifter acceleration rates the 0.904 lifter allows. More than expanse nether the curve should equal more power. Like lines would be the Lunati Voodoo and Hughes SEH line. R. |

My oil pan was already weeping a chip and with my luck, the timing cover wouldn't seal up on the lesser. That'southward why I went ahead and knocked out the pan. That existence said, if the pan has been a on the auto quite a flake, good take a chance the gasket volition tear or not seal dorsum up but maybe that's just my luck likewise. |
