Not sure on the brand but it's an aftermarket smaller neutral balance (running with a weighted b&m flex plate, before somebody says something about it) I do need to time the cam right now it is in there as it came with a double roller timing chain. Timing is set at 21 initial and 37 total I believe. With vac advance hooked up.

Honestly I built this engine back in early 2015 and just broke it in 4 months ago. All of my part choices were what I had in the garage at the time. My biggest complaint on hoe it runs now even after accelerator pump tuning is it is sluggish off the line but 3500 she takes off decent till about 5500
