COOLING SYSTEM

            The radiator installation is most of the swaps labor. It is
very similar to putting in a front oil cooler for a Porsche motor.
You can use either a (heavy duty) 1967- 69 Camaro radiator (911),
1968-72 (heavy duty) Nova radiator (914) or my RSH radiator.
All work well when installed by the kit instructions.  The kit
comes with templates and detailed photographs to help in
this step of  the swap. The recommended electric fans mount
to the radiator with their own shroud. The RSH radiator can
be installed in the 911,912, or 930 without modification to the
gas tank. Because of the danger involved when cutting or
welding a gas tank, and the difficulty in welding so the tank
doesn't leak, it is recommended to use the RSH radiator.
The RSH radiator for the 914 stands straight up and only
uses 1/4 of the trunk space.
       The coolant pump is machined from a 356 T-6 casting,
complete with Chrysler impeller assembly, AN fittings and pulley.
I also sell a heater core and shroud for use with the stock
Porsche heater / blower motor. If you want A/C I also sell all
the hardware to install the Sankyo - Sanden  #508 compressor.

You can install any small block Chevy V8 in your Porsche. Cost and
choice of transaxle are your only consideration. I chose the small
block Chevy because of its length. It is the only V8 I found that would
fit with no cutting or modifacation to the engine compartment.
The Chevy V8 with cast iron heads  weighs 490 lbs. The 930 engine
weighs 510 lbs. The standard Porsche 911 engine weighs 410 lbs.
You can shave approx 50 more lbs off your Chevy by using
aluminum heads.

901: Good choice for basic conversions, engine should be limited to
          300 ft lbs of V8 torque or 225 ft lbs of V6 torque in 1st gear and
          340 ft  lbs of V8 torque or 255 ft lbs of V6 torque in  2nd thru 5th.
          Top speed will be approx. 148 mph @ 6500 rpm with the stock
          31:22 (ZA) 5th gear set. If you want a taller 5th gear, it can be
          replaced with a 19:32 (H) 2nd gear reversed (32:19), where the
          driven gear in the set becomes the driving gear. Then 6500 rpm
          is approx. 179 mph and 55 mph is a comfortable 2000 rpm.
         The stock 215mm pressure plate with the RSH disk will hold
         up to 350 ft/lbs of  V8 torque. The stock disc will hold up to
         260 ft/lbs.

915: In 1972 Porsche started putting the 915 transaxle in the 911
         and 916. It will handle 450 ft/lbs of V8 torque. In 1977, Porsche
         Strengthened its mainshaft and it will survive 600+ ft/lbs of
         V8 torque. 915 ring and pinion must be flipped for mid-engine
         Application(914). The 911 SC clutch assembly will hold up to
         325 ft/lbs of V8 torque. The RSH disc will hold up to 450+ ft/lbs
         of V8 torque.
