I havent done it myself byt i've heard its around $100 - $150 extra when you do a rebuild. Balancing wont let you rev it any harder it will still have a long stroke. The engine will run smoother and rev up quicker tho.

can you buy already balanced crank and pistons and that, or does it have to be done as the engines getting built. also do ACL sell balanced parts.

All the parts get balanced together. Do the entire rotating assembly: Balancer, crank, rods, pistons, flywheel and pressure plate if manual. Ive reved mine to around 6300-6400. Its smooth but that is still dangerous. At that high rpm the the long stroke makes the pistons move at insane speeds. Best to keep things below 6000 IMO.

[EBFalcs]

6000 is almost another 1000rpm over stock though i'd only rev mine to a max of about 5200

[stockstandard]

Stock engines should have no problems getting to 5500-5800rpm

[EBFalcs]

that's impossible they have a fuel cut off a 5500

[stockstandard]

not all of them

[Psycho Chicken]

Yes but a stock engine shouldn't have any issues reving that hard if you remove the limiter.

[EBFalcs]

anyway, if you want it balanced do you have to get an engine place to rebuild it. and how much does that cost

[5L]

my fuel cut off is at 5300

[NEG]

is there realy any point to reving past redline? wouldnt it be better to keep it around the max torque mark.

[stockstandard]

Cost will vary depending on how much you get done and what tolerances it is done to. Best bet is to phone your local engine builders and find out.

Bit of a waste of $$$ if your only going to rev to 5200.

i was talking 5200 is all i rev my stock motor to.
