The 1986 Chevy 4.3 did not have counter balance shafts the '87 did. Racing it with the incorrect block would be against the rules. Billy Lynn or Mr. Greening would be able to supply an experienced answer on the counter balance engine.

I hope this helps.

Thanks You for info. This would be a bracket S10.

No balance shaft. Plug oil hole in back of block and have engine balanced.
