I was bored and did a search. A thread came up on HB. Went tru it and saw some of you are running aftermarket ones. Im running 1 from checkers which is a stock replacement. Is that bad??? Whats the difference from each other???

Some HB's have a SFI rating which means two things ...........

1) They cost more

2) They'll stand up to more abuse
and
IIRC ... Some drag racing classes require them

I killed my little OEM HB very shortly after doing quite a few 6K+ rpm
3rd gear passes dialing in my final WOT fuel ratio

No Doubt In My Mind ... high rpm kills the stocker

Oh you know. lol

But if its STARTING to mess up then there will be some rubber sticking out. When mine went bad it was hardly sticking out though. Maybe 1/4 an inch.

You can look for rubber sticking out the back of it or see if it wobbles when the car is running - look at it from the side as if you were checking timing.

Or if your crank snout breaks off the balancer probably bad too.

I'm surprised you haven't needed something decent by now - spray can make short work of cheaper balancers.

I would add that not any SFI is a good unit. There are several non-SFI units I'd rather run over some of the Chinese SFI units. Grady and I both have Pioneer SFI units - great bang for the buck IMHO. Others like Romac or PP units (get your mind out of the gutter ).

Good luck.

I'm running a PP non sfi balancer and it has worked great. Now I'm only bolt on so keep that in mind. As soon as fund are there for H/I I will probably upgrade to a SFI one just to have it.

I have the PP SFI - works great, no complaints. Have helped someone install the non-SFI PP unit as well - also looks to be a good piece and has held up.

One thing to keep in mind!

I've seen a few peeps go through 3 different OEM HB's before they went to something with more Quality.

I've seen many peeps go through 2 of them as well.

The stocker OEM is known to be not all that dependable.

Don't waste your money on another one!
