JTR 350 swap harmonic balancer

[MetalMagoo]

Going through my JTR manual, page 3-3, it says I'll require a 7.25" or smaller harmonic balancer. Cool. It negelcts to give any part numbers.

 

I'm about to do the timing chains, gears, cover, and finally a harmonic balancer. 

 

FIRST: What balancer did you use in your swap?

 

SECOND: did the timing mark line up with the stock timing indicator?

 

I have searched high and low for an answer to no avail.

 

Thank you in advance.

I’ve used the stock balancer on a couple of swaps; currently using this one on current swap:  https://www.summitracing.com/parts/SUM-161350

 

No, the timing marks have never been accurate for me.  I have always measured it mechanically and adjusted the marks as necessary.

My stock balancer is 8". I was hoping there was an OEM balancer from the 60's / 70's that was 7.25 or smaller. Thanks though, that one is a great price

This is the damper I used. It is 6.25" diameter.

Thanks for the info guys. After searching I found an OEM solution. The harmonic balancer off a 327 is only 6.75".
