I am going to be rebuilding an engine for my CAMARO i am only looking at running 300-350 hp do i really need to balance my rotating assembile.

thanks for your time

Its an option I would and did take. Smooths out the motors harmonics and less stressfull.

If the components your buying weigh the same every thing sould be fine. But with everthing I have seen that won't happen for the extra 125 to 200 dollars get it balanced and while your at it if its a standard have the flywheel a pressure plate done as well as we have see alot of problems in that area.

i had mine done and i was glad did after the guy at the machine shop showed me all differences in weight just between the pistons! then i had the block alined bored and now it's perfect!

It makes a noticable difference! I think it is well worth the money!!

had mine done with the rebuild. found some of the rods were 33 grams heavier then some others. Line bore is a great idea too.
