MetalMagoo Posted August 23, 2021 Share Posted August 23, 2021 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.

jhm Posted August 23, 2021 Share Posted August 23, 2021 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. Quote Link to comment Share on other sites More sharing options...

Thanks though, that one is a great price 1 Quote Link to comment Share on other sites More sharing options...
Miles Posted August 23, 2021 Share Posted August 23, 2021 This is the damper I used. It is 6.25" diameter. https://www.summitracing.com/parts/flu-620101 Quote Link to comment Share on other sites More sharing options...
MetalMagoo Posted August 23, 2021 Author Share Posted August 23, 2021 Thanks for the info guys. After searching I found an OEM solution. The harmonic balancer off a 327 is only 6.75". Quote Link to comment Share on other sites More sharing options...
