383 balancing  

Active Member

Last summer I bought another Camaro with the intention of switching it from a glide to a 5 speed.
Spent the end of the summer trying too figure out a timing issue. The previous owner knew
Nothing about the motor other than it was a 383 . fast forward; puled the motor & trans too start
the change over & check the cam #s for spec’s, found that it had a 400 flex plate with a “internal”
sfi balancer, Crankshaft has indications of internal balancing.
ANYONE, hear of doing this? Is this some kind of Hybrid balance job or just wrong parts used?
New season approaching fast , would rather be racing not sitting in the garage weighting on parts
too return from machine shop.

originally the 400 crank that was put in the 350 block was externaly balanced. that made the 383....but most of the aftermarket brands are internally balanced...
