As stated I am starting to look at what I need to do to build an A/C system for my 914.
Since my power steering seems to be working great I can move on to the next thing on the list.. I am using a "V" belt system and really don't want to change it over, besides the cost may be more than I want to spend. If someone knows a cheaper way to add a serpentine system let me know.. (I have a first generation SBC).
My thought was to decide on a compressor and use the condenser, evaporator, dryer which go's with system..
I've looked into an electric compressor but I have enough amperage blasting through my car already and I don't know what voltage thy run on.. I may switch over to a electric water pump to free up space but I 'm not sure.
suggestions welcome !!!

I am going to try and use the original under dash unit that came dealer installed on the 914 but I am using a suby so the compressor is not a problem. I might have to change the expansion valve to work with the 134a. You might check with vintage air or the other hot rod ac shops for the compressor mounting and a sanden v belt compressor. The condensor will probably need to be a newer aluminum one the same size as the radiator you are using. The fans will need to come on when the ac is on. They claim the old rubber lines need to be swapped out as the 134a needs a barrier type rubber hose. I guess I will use a combination of the old connectors at the u/d unit and the later fittings for the rest of the parts.

The switch to a serpentine belt might get too close to the firewall. A 97 sb chev truck is serpentine and a vortec headed motor. I put a 350 ramjet in a 86 k5 blazer with headers and it was a big job using the vortec heads from the ramjet and brackets from the 86 305 sbc.

There are expensive options for belt drives for the sbc, I think I saw one from march. I don't know if any of them are close enough to the motor.

I guess you are running a alt from a v belt maybe you can go from there to the ac compressor although getting a good wrap on the ac pulley will be a real challenge. Maybe there's some room between the valve cover and the carb or maybe a compressor can run backwards and you could make a small box in the lower firewall to allow it to fit in front of the motor.

I talked to a guy that did a electric s10 in about 89 and he sad he had ac but I didn't think to ask how.

V8 Archie has been putting sbc's in fieros since 84, he may have a solution also. I know he runs the water pump off of a extended shaft in the rear wheel well. I'm not sure about a compressor.
