Alright guys, I have a 400 bored .060+. Speed Pro Hypereutectic Pistons, Stock rods with ARP bolts, Cast crank.
My buddy is in the finishing stages of his 355 build, and regrets balancing his rotating assembly because when they checked it, they said it only threw off 15 lbs. Which isn't bad considering my BBC threw off 650 lbs lol. But the thing is, its $175 to get it internally balanced to 10,000 rpm. Is it really worth it? What do you guys think.
Thanks, Cory
I always balance my engines, even if I'm not going racing with it. Just makes for less wear and increased longevity if they are balanced. Considering what it costs to go through an engine these days, it's not all that much more to know that the balance is spot on and one or two heavy pistons aren't going to be pounding the engine to pieces...
Yeah you got a good point, haha as with my BBC, throwing 650 lbs off. Good thing i got it balanced. I just will have to drop the cash on the table and do it.
Thanks guys
I think it's a good decision. Never have figured out the guys who won't hesitate to drop $200.00 for chrome and shiny's for their engine, but think the balancing bill is too high?????
Once you feel one balanced you'll never go back. :D

haha yeah your right. I'm doing the combo off of Chevy HI Performance. That makes 525 lb torque at 3500 and 428 HP at 5,000 RPM. Its gonna be such a torque monster. Last night I ordered the vortecs, pistons, rods, bearings, rings, seals, oil pump, and so much more haha. Heres a link of that combo if you guys wanna look at it.

If you want to do it right, have the assembly balanced. I would never build an engine that did not have a balanced rotating assembly.
I just did my first engine and it was balanced .....OOOHH what difference from the factory vibrations in the motor all I can say is smooth as silk.
Sounds like what I would say.Quote:
