- Compatibility: confirm mounting patterns, accessory drives, exhaust, intake, and radiator clearances for your vehicle.
- Support and warranties: OEM-backed or reputable crate brands can simplify parts availability and service.
- Fuel delivery: carbureted vs. fuel-injected setups affect installation complexity and tuning requirements.
- Installation considerations: engine mounts, transmission compatibility, and clearance with headers or power steering components.
