Motor & Transmission Cooling, Part 1
Back to On-line build Index Page
We've also included some tips at the bottom of this section to help you out.
Mark is in the mock-up stage on the motor cooling. Mark assembled the front end to determine radiator size, mounting and location (up, down, forward and aft). Different radiator sizes have been mocked-up by using Styrofoam and cutting it to size and shape (Styrofoam can be glued together using a hot glue gun). As you can see from the overhead shot, everything is going to be extremely tight. Keep in mind that the inside to inside of the frame rails are only 24" apart. The grille cowl sides also tappers towards the center as it comes closer to the hood.
*Note By using a recessed small block Chevy firewall, toe-board and using our new X-member, the motor can be moved back an additional 3". This also eliminates the problem with Manifold clearances on Sweet Ryde Vette front Suspension Build
Mark has chosen to change to our Tubular X-member and recess the firewall due to space issues for a radiator.
The front sheet metal was temporally installed so the custom aluminum cross flow radiator from AFCO Hot Rod Products could be positioned as far forward as possible. Space was also allowed for an A/C condenser and lines. Machined aluminum brackets that are bolted to the frame rails support the radiator. Adjustable rods provide the bracing and are attached to the upper control arm mounts.
To handle the fan chores a SPAL 16" Low Profile fan was utilized. Its swirl blade design provides quieter operation and a higher air flow.
To attach the AFCO Hot Rod Products transmission cooler, two brackets were welded to the lower X-member tubes. This location keeps the cooling lines short and keeps the cooler out of the way of the exhaust routing. The cooler is mounted on the driver's side due to the exhaust routing.
Transmission Cooler Plumbing
To handle the fluid needs Mark is using AEROQUIP’S new nickel plated aluminum fittings and braided stainless AQPÒ Racing Hose. The new fittings from AEROQUIP offer the look of stainless without the cost or weight. Two lines were cut to length and assembled with fittings to connect the cooler to the transmission. Fittings were installed in the cooler and transmission to attach the AN hose fittings to.
The trans mount spacer was drilled and tapped to attach the Made For You Products T-CLAMPS that secure the lines. A metal bracket, was made from some square tubing and tack welded to the x-member to attach the Double Place T-Clamp from Made For You Products to finish the installation.
Cooling tips
This is what we have found works best for us. Everyone has opinions in this area.
*Always use a quality radiator with the capacity to cool your motor.
*Don't retard the timing of the motor for that "lumpy" cam sound. When the timing isn't set right, the motor just runs hotter.
*I've always used a 160 degree thermostat on carburated motors and had good luck.
