An engine steady bar to reduce rotational torque was made using a rear shock link from a CB car. A mount was added to the back of the left side of the engine, and a reinforcing bar made from 1/8" steel stock was welded onto the firewall just below the heater box opening. The shock link mounts to the back of the engine and to the firewall just below the heater box. There is plenty of room for the big nut on the end of the shock link inside of the heater box opening.

Based on the MGB V8 books by Rodger Williams, an adapter plate was made out of 1/4" steel, drilled and tapped to accept the original heater control valve.

To help keep things cool (remember I live in GA, it gets hot here) an oil cooler (EAR-41608ERL, Summit Racing) was added.
Note that all the fittings were converted to AN type because there is a wide variety available.
Here the Twist-Tite blue 8 AN hose was used with Summit Racing Twist-Tite hose barbs, which made running the lines easy.
In this picture you can also see the 90 degree angle on the bottom radiator outlet.

Oil cooler added. This is original placement for RB cars that had coolers.

The radiator was the original radiator out of this 1977 MGB. The inlet was modified to take a 1.5" hose and set at a 45 degree angle. The bottom outlet was also modified to take a 1.5" hose and was set at a 90 degree angle pointing to the center of the car.

The Radiator was actually moved back about 0.5' to allow space for the AC condenser. There was still plenty of space between the radiator and the cooling fan.

A port for the 185 degree temperature sensitive switch which can be seen in the picture (Summit Racing SUM-890017)was added to turn on the original dual electric fans that will sit in front of the AC condenser.

In this picture you can also see placement of the expansion tank for the radiator and the remote oil filter.

I decided to move the steering rack back about 1/2 inch. This got it in behind the harmonic balancer so there wasn't any rubbing issues and in retrospect, wasn't enough to affect the steering in any way. In other words, no bump steer.

Steering Rack/ Harmonic Balancer Issues

Test fitting the engine/transmission combination showed that there was an issue with the harmonic balancer on engine and the steering rack shown here. The engine mounts had the engine so low and moved back that the rack and balancer wanted to occupy the same space.There were two options, remove the harmonic balancer from the engine, but this could cause vibration issues shortening the life of the engine (those balancers are on there for a reason). Or move the steering rack back, but this could create something called bump steer. See the next journal entry for the fix.
