Adding Vintage Air to inline 6 250 ?

[Danman09]

I just picked up a 1970 c10. The guy took it apart, put on all new bed and fenders with ash and stainless, new front fenders, had it painted , frame off, had a machine shop rebuild the 250 inline 6, dropped the motor back in then quit. Never put the bolt-ons onto the motor. Left engine holes all covered. It sat in his garage for years and I asked and got it for a steal. Here's the question. It has power steering , front discs, and power brakes. HEI distributor and original one barrel Rochester. Will this motor handle the addition of Vintage Air ac if I install it, or should I just not try to finish the engine assemble and buy exhaust etc for this and just get a V8 ? I would like to drive this truck almost daily.
