Be careful choosing a dampener, SFI does not mean a quality made product. ATI made in USA, and if I'm not mistaken powerbond made in Australia along with a couple of others I can't recall will not blow up.

ATI. but if you have to go cheaper use Powerbond. I've had a couple customers with Pro Products SFI dampers that blew up

I had a POS Professional Products for about a year, it came loose where it was bonded together. The outside was spinning on the hub, but it did not come apart. It makes one hell of a racket when you kill the motor and it keeps spinning for a second !!! I know have ATI's on both my motors, very nice product.Save your money and get the good stuff or you will be buying twice.

How do they get an SFI rating if they blow up?
they don't, i think they mean the motor blew up

And of course it was the dampners fault...............


Every part has it's place, and when to be used

I say if it turns any kind of Rpm and makes HP

BUY the ATI, money well spent

And on a 400 sbc you WILL want to use the 8" damper

That is what I've seen happen twice and once the outer ring came completely off. That what I meant by 'blown up'.

Damn, i got lucky then !!! I shut it down as soon as i heard the noise and loaded it on the trailer. Did'nt actually find what it was until the next day after i got it in the shop. Glad i called it quits that day !!!
