    Hello everyone. For the past 17 years my family has owned a 1963 OLdsmobile f-85 station wagon. I know that they did not make a turbocharged wagon that year (i wish they had), but my car did have the high po 215. Anyway we traded that motor for a rebuilt 215 buick motor that was decently built up. That shot a push rod out about a year and a half ago, and locked the motor up (motors fine now turns out). I bought the car from my dad then, and got a 2 barrel 215 off of ebay for a good price. The motor is now in the car, but my problem is that after about 10 minutes of idling the motor starts to overheat. At first we thought it was a stuck thermostat, so we took that out, no luck. When the motor went in we put a fresh fuel pump on it. The one thing I did change on the motor before it went in that was sort of major was putting the old 4 barrel intake manifold on it. It still has the two barrel heads on it, and I have 4 barrel heads in the garage, and I was wondering if the water jackets are different on the two heads, or if its another issue. I know it sounds awful to swap a buick 215 into a high po wagon, but the car is also a traditional custom. It doesn’t have door handles anymore, its got jaguar headlights, and a host of other mods. Oh yeah, its a factory ac car as well. One day I would love to get the turbocharger setup for it.

    After seeing no response to your question, I thought I would let you know that the intake manifolds that fit the 215 blocks are all the same. This is NOT your overheating problem. I would check out the radiator next. They have a tendency to plug up and need to be cleaned, channel by channel, with a flat rod, both tanks removed. A boil-out cleaning job will NOT do the trick! A re-core will do the trick too, just more $’s!
    I have built a “Jetfire wagon” fun! You can build one too. Have fun………..

    Thank you so much for the response! Thats music to my ears, I was afraid I was gonna have to go through the motor, instead of simply working on the radiator.
