Recommend a Harmonic Balancer internally balanced

[duster1970]

Planning a 416 build and trying to decide on a harmonic balancer. Anyone have a favorite or least favorite? This will be an internally balanced combination. Thanks in advance.

I've been using the Pioneer SFI 872037 on my internally balanced 360's for many years without an issue.

* The photo on the Summit site is not a pic of this balancer, but I think you can Google to find one. Couldn't hurt to shop around as well.

I purchased the Summit harmonic damper, part number SUM-163273. I haven't run it yet, but there are reviews up on it. I have no need to run a SFI 18.1 $300+ damper.

Here's the link.

Of course, mine is "just a 318, with the 3.31 stroke," and since you're running a 4" stroke I don't imagine that you'd be winding it as high as a stock stroke 318/340, or even 360...

I won't use any stock type, non-SFI one again. They're all junk and slip. The SFI ones are tested and tend to not have problems. Have a $75 balancer cost you $2500 in a blown engine and you'll realize how stupid not spending that extra $225 is...

No reason to skimp on this with an elastomer style damper.

Use either a Fluidamper or the Innovaters West.


Rubber band style dampers are obsolete unless you can build your own. And, you have the ability to test and develop a damper.

Yes, there are many in use. They were and are used by OEM's. It's because they do a reasonable job, across a relatively narrow RPM, FOR THE LEAST AMOUNT OF MONEY AN OEM IS WILLING TO SPEND.

Thank all of you for your insight. This will be my first stroker. Can't wait.

That Jeg's unit looks exactly like the Pioneer brand I use, except mine came clear-coated. Very likely relabeled for them.

I ran a crappy CAT fluid damper and it ran great. That was a hulk of a damper.

Those are not bad, chink things.

The biggest issue with offshore things like this (any part for that matter) is that you MUST verify everything dimensionally. I have seen some with with .007 press fit and some that were .004 loose. So from bash it on tight to fitting like socks on a rooster.

You have to measure everything.

Check out ATI, can't be beat but they're pricey. I use one on my 2500cc ministock motor and regularly turn 8000 RPMs on the track. In three years since I installed it, I see next to no bearing wear when I do an end of season tear down.

yes...the one I got is clear coat ...and i believe it is the pioneer balancer
