have a 502 with a roots blower on it. id like to keep the motor fully assembled well lifting it into the boat but not sure where i can grab it. i was looking online and some of the Blue motors have lifting eyes off the blower studs/ manifolds. should that be for a iron block/ alumi head combo? or should i be trying to get at a bolt hole on a head?

I have always used a sling around the exhaust. Does not scratch and I can adjust the motor attitude front to rear to help it install easier.

like a lifting strap around the manifold or off the exhaust manifold mounting bolts?
