Getting ready to do a cam swap on my Magnum headed 360 and have to upgrade the valve springs. Really don't want to pull the heads to upgrade the springs. Current springs should be P5249464 based on what I have found online to have come on the MP R/T heads I am running. Swapping to the...

Hoping someone can shed some light on a confusing (to me) motor. Numbers on the front of the block are 0W360HP0211 and a big weird stamp of 4097. So, 1980 model 360 HP built in the Winsor plant. I expected to see a Julian date after HP, but 0211 makes not sense so I am assuming that is the...

Building an LA/Magnum hybrid Frankenstein motor with an LA block and MP Magnum R/T heads, Hughes retrofit rollers, OEM 5.9 cam and stock Magnum rockers. Currently I am measuring my lifter preload at .085" with a Ford pushrod measuring 6.88" long. I know the recommended preload is...

Plenty of people have bolted Magnum heads on their early blocks, with virtually no problems (with the right lifters and pushrods). I should have known better than to think it would work that well for me. I assumed that because the factory heads bolted on fine, the aftermarket MP cast iron R/T...

Little bit of background. I've asked a couple of questions about my problem, and given this background before, but figured I would bring up to speed anyone that may not seen the other one or two threads. I got my '74 Duster 360 out of wrecking yard back in '91 or '92 and rebuilt the motor...

Anyone have the front off their motor and willing to take a measurement for me? I need to know how far from the front face of the block to the outside of the cam and timing chain. Something like an 1". Need to figure out some clearances for my crank position sensor idea. Thanks.

Anyone know the distance between the crank centerline and the cam centerline on a smallblock? Tried googling it and came up blank. Thanks.

Some may remember a thread I started about trying to find a way around the crank pickup problem while trying to swap the Magnum SMPI stuff onto the motor in my 4 speed Duster - http://www.forabodiesonly.com/mopar/showthread.php?t=78887 . I'm still trying to work around this problem as I don't...

I've been chasing a motor noise since I got my Duster running again a year and a half ago (no garage, discouragement, lots of reasons for the delays). Not driving it any, other than around the block hoping the motor would warm up and the nosie would quit. The motor sounds like a diesel motor...

I've got a 71 Dart with a 318 and an dual plane M-1 intake. Popped a vc off tonight and confirmed that it has the stock 318 heads. So, unless I am mistaken about the M-1 intake, I have a large port intake breathing into small port heads. I've always heard that was a bad combination, but how...

I've been debating about some kind of MPI swap into my Duster (both Magnum and 5.7 Hemi). One problem I have been struggling with is the required crank position sensor in a Magnum swap and how to keep my 4 speed in the car and make it work. Just noticed that the notes for the MPI kit that...

I have a 74 Duster with a 360 and since last fall when I got it running again, it has been making a huge rattling noise on the passenger side of the motor. It sounds more like a deseil tractor motor than a gas motor. I've replaced the lifters thinking it was lifter noise (which my brother agreed...

Need to get into the bottom end of the 360 in my Duster and I would rather not have to buy another set of gaskets as I have what seems like about 4 sets of oil pan gaskets left over from the engine sets I've bought over time. Problem is I can't identify if they are for a 360 or 318/340 as I...
