I finished installing the March drive kit tonight. I am really impressed with this kit.
I installed the radiator support and did some measuring. A two inch recessed firewall isn't going to provide enough clearance. And I didn't want a recessed firewall at all! I need to see if I can recess the radiator into the support. I may also have to run the top fan as a puller and the bottom one as a pusher. Not too thrilled about this, but I will work something out.
After work, it was 102 F by the thermometer on the front porch. I sat in front of the fan and cleaned the front of the heads and block, chasing the bolt holes with a tap. Then I started assembling and installing the March drive. This is a great set-up! The instructions could use more photos and exploded views. And, for the life of me, I couldn't find an allen wrench to fit the pulley cover machine screws. But this thing fits great. All high quality pieces. Glad I got it over trying to piece stuff together off of other engines. Didn't get to the AC compressor before it started getting dark. Wednesday night. Hopefully I can get it installed and test fit the radiator on the same night. I will say this; the engine is going to have a major clean up to look right with this drive kit!
The Northern radiator is wider than the stock unit. The narrower stock unit actually is recessed into the support. The net result of this is that the tanks on the Northern radiator hit the core support. The first attempt at making the radiator fit involves cutting 2 aluminum 3/4" square tubing to length and using it as a spacer on both sides. In the second photo, you can see that the tanks clear. It is possible that the core support will need to be modified to allow the radiator to slide forward in the car. The holes still need to be drilled. Then, the radiator and the March drive kit will be checked for clearances.
Finally, something other than welding and grinding sheet metal. The dual fan set I got from Skip White is just a little bit too narrow for the Northern Radiator. So I had some stainless brackets made. I went to my favorite old-timey hardware store and picked up some stainless fasteners. I attached the fans to the brackets using 1/4" stainless carriage bolts and nuts. I used anti-seize to make sure the stainless didn't gall and leave me with a mess. The radiator flange was then drilled and the fan and brackets were attached using allen type button head stainless bolts and nuts.
The new channel was fit and welded in place. A portion of the bottom of the b-pillar was cut back to allow for a flange to be in place to weld to the floor portion of the rocker box. Then the patch was cut out and welded to finish the b-pillar.
If all goes as planned, I will check the radiator, fans, March drive kit for clearance. In a previous post I said that after the clearance was checked that I would take the body off the frame. Actually, before I do that, I have to install the seat and fit up the brake, steering column, and AC. The thing is, this car is starting to come together and I am psyched!
