Patient: 1964 El Camino that I purchased with a stock 1978 305 w/ Rochester 2GC. The 'glide has to go, so I sourced a 200r4 from a 1985 Monte Carlo SS. I also snagged the intake and Quadrajet off the donor car. When I ran the numbers on the manifold and carb it appears they are both 1979 so must have been swapped together in another life. I don't mind the 2-bbl but the TV cable to mate this to the 200r4 is over $200. I got the cable and brackets off the donor so now I have the option of the QJ setup. Again, the 305 is bone-stock and runs great. Any downside to the intake/carb upgrade?
