Pulled a Magnum motor from an 01 RAM, and I'm dropping it in a Demon that currently has a 340 and a 727. I plan on running the serpentine setup, so the stock style one piece balancer is fine. It is an external balance balancer. The flexplate on this Magnum has no weights on it, and I assume the torque converter on this particular truck the motor was pulled from has weights. I don't have the converter, and want to use the zero balanced converter I currently have behind the 340 in the 727. Does anyone which weighted flex plate I need to use so I can avoid balancing and adding weight to my converter? I've read lots of posts and I am still scratching my head over options.
Magnum balance....

OK, now that's AWESOME! Part of me mourns at a cost free alternative to pitching a stroker kit to the wife, but 5.9 will have to do

I agree. Get one from a salvage yard, much cheaper.

If the factory Ram flexplate didn't have weights on it, you don't need 'em on it now; it's an (almost certainly) internally balanced 5.2! You say you're running the stock style one piece balancer (Which I assume you to mean vibration dampener)...which one? Magnum or 340?
If you think your Ram mill is a 5.9, you need to make sure before you go hanging (or removing) weights on it. The 5.9 had weights (on the flexplate), and they were different than the 360 weights! This goes for dampeners, too.
Magnum mills didn't have weights on the converter that I've ever seen and I'm wagering you have a 5.2 and just need an unweighted converter, flexplate, and internal dampener.
Side note, I'm confused and this info may be totally worth what you paid for it.

Yeah, just to be safe, I would clean the area in the front of block right below the driver's side cylinder head(area behind the power steering pump). Depending on the year, it will either have the liter size (5.2 or 5.9) or the cubic inch size (318 or 360), along with other numbers that will tell you the year and other info.
5.9s should have a flexplate with a weight on it and a harmonic balancer that has a section missing out if it. 5.2s will have a flexplate with no weights and a balancer that isn't missing any section.

Yeah, just looking at the number on the side of the block would be way easier than my way. Haha

Hey not to hijack your post but i have a balance question my self.....i have a 5.9 that had a wights on the flex plate i have a neutral converter and just got my hermonic damper (converted to v belt since the front cover was already gone) now my new balncer came with wights and instructions on what one to use either im not reading it right or its just late but im not sure if i need to wight it or remove it
If it's like this one- Pro Products Street Dampener for Small Block Mopar - then it needs the 5.9 balance weight. The 5.9 is balanced on the dampener and the flexplate but not the same as the LA 360.

Yes that is the one purchased but it only list 93-97 externally balanced
Should be good, use the 5.9 magnum weight. The 2000+ has the dampener and the pulley all one piece but the balance is still the same.
