As you can see, I made little effort at making it look pretty.  For me, cleanliness, reliability, simplicity, and functionality are paramount.   In addition, with the theme of the car being updated classic, the installation was done to appear as close as possible to what GM would have done.  

As can be seen above, a GM R4 compressor is being used for the A/C since I already had serpentine brackets.   While the Classic Auto Air system comes with a Sanden compressor, the kit can be ordered less the compressor.  To use the R4 compressor, CAA offers an optional billet aluminum adapter to allow their hoses to be used with the R4 compressor.  This is all detailed in my write up which is available on the Interior page of this website.

The engine and exhaust specifications are below. 

 Short Block

  • GM Performance Parts  ZZ4

  • Competition Cams 262 hydraulic roller

 Cylinder Heads

  • Air Flow Research 180 cc street heads.  Flat milled to achieve 10:1 Compression

 Induction System

  •  GM 1990 Camaro EFI electronics

  • Tuned Port Induction Specialties Miniram intake manifold

  • 52 mm throttle body

  • 24 lb/hr Bosch injectors

  • Custom Tuned E-PROM

  • In-tank fuel pump


  • Borla 1 5/8" stainless steel exhaust headers

  • Dual 2 1/2" pipes with "H" crossover

  • Dynomax Super turbo mufflers

  • Glass packs just downstream of the headers to act as resonators


  • 1990 Camaro serpentine accessory belt drive

  • Custom cold air duct with relocated manifold air temp sensor

  • Mid-90's Ford Taurus Electric fan

  • Corvette HEI distributor with MSD high output coil

  • Aluminum radiator

That cold air duct is a 4" diameter aluminum tube with associated rubber elbows (upgraded from the original 3").  Having relocated the battery to the trunk, it opened up that location for routing the air duct to outside the engine bay.  The tube penetrates the floor of where the battery used to sit, and it terminates to a low profile Spectre air filter.  The intake air temperature literally dropped over 40 C (as confirmed on my scanner reading- with temp sensor in the same location relative to the air filter for apples-to-apples comparison).

As far as performance, the engine makes around 400 hp but still nets about 23 mpg on the highway.  It's a great combination for a street driven car.

A recent upgrade to the cooling system consisted of a mid-1990's Ford Taurus electric fan and an aluminum radiator.   The fan is a two speed model and moves an incredible amount of air- reportedly around 3500 cfm on the low speed and in excess of 4000 cfm on the high speed.  To date, with the aluminum radiator, the low speed mode has been more than sufficient to cool my Camaro with the A/C on in traffic, in 100+ deg outside temperature.   Both speeds are controlled by the ECM, in which I can set the on/off temperatures to whatever I want.   For power, the main power input for the high and low speeds is switched by a Bosch 75 amp relay on each input.  The fan's airflow capability requires a lot of electrical current, so to be conservative I used one 75 amp relay for each input.  I generated an installation write up that shows how to mount the fan to the radiator (without those lousy zip ties).
