Use the exact same size, shape and color fuse as the blown out one you removed from the fuse box

Drain coolant, remove anti freeze plug from block (corresponding size to the size of your heater coil plug) and install this plug carefully, using a large nut and a hammer. Refill coolant, let engine idling warm up, check coolant again and the installed heater plug for leaks. Now you can insall the cables, away from any moving or hot parts.
Chevrolet used the 350 and 400 small blocks and the 454 big block.
The port for the block heater is a small hole approx. the size of a quarter located on the windshield side of the motor, closer to the driver side of the car. It is just below the head (top part of motor) in the cylinder block. Make sure the hole is clean of dirt and debris by blowing it out, then simply push the heater element in until it clicks, that's it! ...well then you should plug the cord in... but that's it I swear!
