Hi Adam,

6cyl red motor, I'm using Romac 0201R, seems very good so far,

Regards Simon

i bought a powerbond race balancer for a motor im building. romac make balancers too. probably steer clear of any other brands apart from these 2

B & M are meant to be good too, but i'm not sure who sells them or if they are made anymore? Think they might have been a little more $$$ than the romac.

I bought a Powerbond Race balancer for my 235 stroker 186 at the Summernats today. Looks the goods, machined steel and Aussie made - how can you go wrong?

SikRoDoMoflex balancers are O.K too.

any chance of an inline 6 chev balancer fitting? summit racing have fluid filled balancers to suit the inline chev 6. might be a good one for the stroker?

The Chev straight 6 (250-292 etc) and 90deg V6 balancers are dimensionally the same as the SB balancers (and in some cases the same p/n is used for all three applications). I'm unaware of any others that are a bolt-on fit with the Holden six. Bigger balancers can be sleeved down to fit (keeping in mind the torque loadings that the sleeve has to transmit) but would require a bigger seal boss be welded into the timing cover. The big block Chrysler balancer looks good - it's relatively narrow and has a big enough bore to allow a reasonably thick-walled sleeve. You just have to house the (much) bigger front seal.
Edit: it just occurred to me that you might have more options if you dont turn the snout of the Ford (stroker) crank down to the Holden diameter. NFI what the snout dia. of a 221 crank is though...

not sure if 221 is same as 250, but a bloke with a crossflow cortina that runs aspo mid 11's down this way sed he had the crank turned down only a small amount for a sbc balancer, wait, mightve been balancer reemed out and the bum of it turned down, cant remember but he reckons it was not much trouble at all. Fixed his flexplate coming loose as well

food for thought

just curious, how do you modify the massey fergusson unit to fit?

Mate, these balancers are UNREAL !

Seriously, I was having trouble with the outer ring moving (budget track car that sees 6500 - 7000rpm occasionly.)

More of an XU-1 copy than a full on performance balancer.

So far, so good.
