I run all the atomic parts Matt, they go great. After sales service is the key with making these big power plants. If you want a motor build with a mix of parts call iDyno.com.au tomorrow in NSW and just ask Brent for a street version of my motor. He and I use all brads and DLM gear. It's not all about the gear it's about the assembly of the parts and tuning of the combo. Use the correct gear for the job. Correct cams for turbo and head combo.
