ID My Harmonic Balancer Please....
sancofw:
I picked this Harmonic Balancer up at Pate Swap Meet last week end. "King of the Garage" honors to whoever can ID it.
It is a 3 bolt 69 design. Has numbers on the back that look like experimental numbers to me:
XE144471 & XL149247
Pictures....
Bossboy302:
I'm going with t/a balancer used '69-'71. For use with internally balanced crank, good for 9k rpm.
AREA 351:
I think ford used this same basic design from the 289 lemans race engine, 302 tunnleport race version (street version had full counter weight i think) T/A boss 302 and even some early 351C race engines i saw from Bud Moore. I bought a box of these years ago from a fellow in GA they had the XE, XL and XH numbers on them, some had shorter crank snouts for some form of a dry sump system gear or counter weight hatchet. The Ford Motorsport E2ZM-6316-A looks just like it but it has no esentric at all it is zero balance. Those two holes inside the hub by the crank snout i think are to turn a mandrel?
TA28:
forrest is it fully degreed?most of the t/a boss balancers i have seen were full degreed. i am leaning more to the 302 tp part
the 1 thing about the ford motorsport units is on the timing cover side the outer ring has a lip that covers over the rubber and hub parts to prevent the outer ring from flying off if the rubber fails. i have seen this happen. and all nascar teams pinned to outer ring on the pulley side.
70BossTA:
I would agree with Chris and say this is a Boss 302 T/A or Tunnelport 302 balancer. Looks like it was used in an non-T/A application as shows all the holes everywhere to get the weight off. That means that to use it in a T/A motor with heavy rods and T/A crank would be a challenge. Just keep that in mind, not a big issue with modern engine parts, so it may be a fine purchase. Again look for the full degree timing marks and marks for setting the valves too.
