?
I have a CZ valve body I bought off a board member. It has not been put in a trans yet. It was at a good price, so I bought it as a spare. I have an 87 BRF that my wifes first born gave me. I can/t tell any difference in it and my 85 BQ as far as shifting hard. Yes my son and I and Scott when he gets his new ride going are, are using the dual fan set up off the late model Z and Tran Am. I am using a adj. thermostat from NAPA, that goes in the upper rad. hose, which signals a relay to turn the fans on. The fans, when in the Z/s, are wired to come on one at a time. I wired them together so they both run or don/t run at the same time. These fans are GREAT. You can watch the temp gage drop when they come on. Some what hard to find in the bone yard, being late model. You won/t find any in Central IN. I am always on the look out for them.
So no, they are not controlled by the computer.
I have a fresh Stage II short block in my car, Looking for some reliability, and higher than 22 psi, with all my old parts on it ( heads, intake, headers, alky) John Craig built me a new 66 turbo, using an 87 housing. I could not gain anything if I went above 22 lbs. of boost last year. Had it out on a country road yesterday. I was not that impressed with it. Will be CARRYING it to Norwalk Sunday,( I notice you/all in Bama like to CARRY your stuff instead of haul it) hopefully I won/t come home licking my wounds.
