I have a friend that has 700+ rwhp (APS twin turbo) GTO and didn't have problems (stock bottom) until he lost fuel pressure, went lean and broke the #7 piston ring land. When it was disassembled, everything was in perfect condition. No crank twisting, damaged rods or any damage at all. This doesn't mean there will not be problems at some point with our pistons/rods. If you want to be really safe, you can get a Compstar rotating assembly for ~ $2000. They're excellent parts for the money, come fully balanced and ready to assembly. You would just need to have the block machined and you're ready to assembly/go. |
The OP is asking about making 500whp
N/A though.
