Frequently Asked Questions

Q: Is this motor plate compatible with all kart chassis types?

A: This plate is specifically designed for the Intek 305 and Honda GX390 engine footprints. While it provides a universal mounting surface, ensure your specific chassis rail spacing allows for the dimensions of these big block engines.

Q: Does this plate include the sliding top assembly or clamps?

A: No, this is the motor plate only. It is designed to be the core mounting surface that pairs with your existing mount system or slider assembly.

Q: Why is a billet plate better than a standard stamped plate for 305/390 engines?

A: Big block engines produce significant vibration and torque. The heavy-duty billet construction prevents the "slop" or flexing common with thinner plates, ensuring your engine stays perfectly aligned for consistent power delivery and improved track times.

Q: Can I use this for other engine classes like the LO206?

A: This plate is custom-contoured specifically for the 305 and 390 big block configurations. For LO206 or other engine classes, we recommend using our dedicated mounts designed for those specific bolt patterns.
