like everything, yes and no lol.
the way ur saying would work perfectly, but then we would have to supply the different hoses to block up the water pipes that are now obsolete, and then supply an oil cooler/adapter setup - both of which are added cost
the other way is to get these adapters made which bolt the 25 aac onto the 26 plenum and its done.
re daves car, speaking with mick yesterday, he is going to just remove the aac control all together, as the haltec has that function built into the ecu to control the cold running.
i'm off to the machnist, see ya in 3 hrs
