| RE: Z code 1961 |

The Z code on the 1961 full size Fords was used on the 300 horse 390, the 375 horse 390, and the 401 horse 390. There are ways to tell the 300 horse car from the 375/401 cars even without the engine in place. The brake line on the 300 horse ran under the engine attached to the crossmember. The 375/401 brake line ran across just behind the radiator attached to the front crossmember. The brake line mounting holes in the engine crossmember are drilled no matter which engine was used but they are not threaded on the 375/401 car.
The 300 horse used a 5/16 fuel line while the 375/401 used a 3/8 fuel line. The 300 horse was available with either vacuum or electric windshield wipers. The 375/401 was only available with electric wipers due to the larger camshaft causing lower engine vacuum.
As a side note, the 401 horse engine came from the factory with the 3x2 set-up in the trunk. The mechanic at the dealership installed the 3x2's as part of the new car prep. I just wonder how many customers got the single 4 intake set-up when they picked up their new car? Or how many mechanics took the 1x4 aluminum intake set-up home? |
