Are all 93 to 97 Camaro LT1 engines balanced in the same fashion? I'm asking solely due to a crankshaft I just saw for sale claiming otherwise...


"Reconditioned engine crankshaft for 86-93 350 SBC/92-94 LT1 engines. Crankshafts have been inspected, magnafluxed, chamfered, and polished. All cranks are standard on the rod and main journals. Ready to install.

Although this model crankshaft is balanced for 92-94 LT1 rods (stock), you can use this in 92-97 LT1 engines as well as 86-97 305/350 1-pc rear main seal engines if it is balanced.

Replacement for the following:

86-91 350 TPI Corvette, 92-94 LT1 Corvette
86-92 350 TPI Camaro/Firebird, 93-94 LT1 Camaro/Firebird
94 LT1 Impala"

The reason this concerns me is due to the fact that I was planning on using a '95 hub, balancer and M6 flywheel on a used '94 long block that I'm in the middle of assembling. Does this crankshaft description have any merit, do I have anything to be concerned with? Thanks in advance!

It would use the same balancer & flywheel. It most likely has to do with the bobweight used for the factory balancing. This would be dictated by forged vs powdered metal rods, and heavier early pistons using wide ring packs vs lighter hyperutectic pistons using narrow rings.

Sounds reasonable, this is the first mention I've seen of any differences. Hadn't even thought about it up till this point. The rotating assembly is 100% stock.
