balancer decision
I am trying to decide which balancer to buy for my Gen-1 383 buildup. This is a street car build under 400hp that started as a 327.
After looking on Summit I came up with these 2. But they seem to be very different because of the diameters and especially the weights.
SO what do I need to learn to decide?
Pioneer Street Performance Balancers:
Part #'s
PIO-872001
PIO-872002
Appreciate any insight

I just put a 6" ATI Super Street Damper on mine last weekend. The Super Street is not SFI approved but my old L48 won't ever rev that high for that long anyway. I was pretty impressed with the way it was made (right here in the USA). It's pretty innovative in that you can unbolt the damper fom the center hub and bolt an ATI Super Damper on the existing hub if you ever want to upgrade. You do have to hone it a bit to get it on. they give you the tolerances in the installation instructions.
Both Summit and Jeg's carry them. Check prices. When I got mine Jeg's was a lot less than Summmit for the same one.
Pioneer has a very good reputation, too, from everything I read on other car forums. If I'm not mistaken they are made in Australia.

Al,
Myself, I would first look at a GMPP 394709 8" hi performance nodular iron damper for your application. Used several over the years on some high horse and high RPM motors. The 872002 Pioneer would be an option, they make decent stuff. The cast iron GMPP would be a decent option as well.

EDIT: I just checked Scroggins and the 394709 is listed at $125
Good Luck,
Scott

Good point Jackson, I forgot to mention that my engine is Internally balanced.
Why is 8" better than the 6.750? Reason I ask is the 6.750 I believe will work with my stock timing chain cover as the tab or timing pointer that is welded on the cover won't work with a 8" one.

put the 6 3/4" on ... not that much difference. 8" has bigger mass & better dampening. But if you have tab welded for 6 3/4 then get that. I run lite 4 lb dampers on true race circle track motors ... but yours is a mid-perf street motor so I suggest a "normal" mass.

I understand there would be compromises most of the time, but was just wondering with these new high performance parts if they have been able to make the leap to something for nothing with either new design or materials, or is all about the weight?

Tab should be 1763 $18
I'm not sure if the finned damper was carried over to '68 though, I need to check on that.
I didn't see that 805 part number but that is the correct GM number. Here is the replacement version for reference. THe -709 would still be a better piece.
Replacement balancer not finned.
