Speedwaypart number 91015357. To establish your TDC mark you need to set the engine on TDC compression on the #1 cylinder, and install the tape so that the TDC mark lines up with your timing pointer, or the zero mark on your timing tab. If the timing tab is correct for your balancer, and the balancer outer ring has not sliipped, this should line right up with the line machined into the balancer. It is always a good idea to check to be sure it is not off.

Will this Harmonic Balancer #91015357 fit my 383 Stroker with a 400 GM crank? I have a 383 Stroker with a GM 400 crank I am trying to find out if this 383 stroker is a internally balanced or a externally balanced setup. This was built years ago (20+) and the machine shop is out of business so how can I figure out what I need to do!

When a stock 400 crankshaft is turned down to a 350 main size in order to build a 383 it will most likely be externally balanced, but of course that's not always the case. Your best bet is to inspect the balancer that came off the engine to see if it is an 350 type balancer or if it is a 400 type with the external balance weight cast into it. Also look at the flywheel or flex plate that was on the engine. If it has a weight on it like a 400 then you can be confident in knowing you have an externally balanced engine. If there is no balancer or flywheel on the engine then you are probably going to have to take a good guess at it. I would say its a 90% chance that it is externally balanced and would require a 400 balancer and flywheel.

No this damper is not made in the US. We offer a Fluidamper 755712615 which is made in the USA. To be honest every balancer you find for sale new under the $300 range will be an overseas manufactured item.
