I plan on rebuiling a 1972 1.7L engine. The car originally had AC which I plan on reinstalling (missing from the car now). I have a purchased a DPD system like the original. I want to keep the stock FI system and want to keep everthing else as stock as possible, but with the addition of the AC, what can I do do increase the power to accomadate the AC, or with the new compressors do I need to do anythink outside of stock? I realize larger pistions/jugs are available but at what cost and risk? The objective is is not a rocket ship but a good driver with good reliability and the ability of the engine to cope with Florida summers.

Thanks in advance.
