1966 Chevy El Camino Big Block And Turbo 400 Trial Fit - Wide Load

Once the motor mount and frame brackets were bolted on, we lowered the big-block into its new cradle. There's no trick to it; we just took our time and constantly checked our clearances from every angle as we dropped in the engine.

Once the motor was close enough to the transmission, we went ahead and mated them together and tightened each bolt with a 1/2-inch box wrench.

The torque converter must be bolted up to the flexplate, so using the supplied bolts and washers from Monster, we fastened each one with a 9/16-inch wrench.

The mounts were next. We lined up the bolt holes and slid in each bolt from Ground Up's motor mount kit. We tightened them down with 5/8-inch and 11/16-inch wrenches.

With the headers already in the engine bay, it was only necessary to release the bailing wire and shimmy them around until we met them up with the exhaust ports of our RHS cylinder heads. We placed the gaskets supplied by Doug's and tightened each bolt with a 5/16-inch wrench.

Locked and loaded, we could focus on getting our new crossmember from Monster, sending our Doug's headers to get coated, the manifold, and the ignition system to get this El Camino rolling down the street.
