Well I've not gotten a lot done over the winter but I have done a lot of digging into the drivetrain on this car and have decided to give the pirate salute to keeping with tradition. I pulled the valve covers off the running motor and found copious amounts of metallic debris greeting me with an ever so menacing twinkle. By any logic and reason the motor runs but needs a rebuild before I destroy something serious. After digging into my spare motor to figure out what the "knock" was.(as described by the old man I bought the car and parts from) Unfortunately we found the crank was snapped just after the number 2 crank journal. It appeared as if the motor had continued to run for some time after the crank snap because the bearing journal was worn almost through to the bearing cap bolt hole. Number two engine trash.
I ended up selling the two motors to a guy that has a small V-8 museum in his house in town. He collects one from every family and sub-family of American V-8 which he restores, paints, and installs on custom motor stands for display in his private collection. Every so often he pulls each motor onto his custom made dyno and runs the motor to circulate the fluids and generally annoy the neighbors. Anyway I am out of the Cadillac motor business so now I turn to alternatives.
I measured up the Chevy small block I have in the garage and what do you know? I will be able to run a GM drive train with no special adapters and I can build it for pennies on the dollar compared to the caddy. I can have reliability, power, and modernity all rolled up into one.
The plan:
84 350 SBC bored .030 over
383 stroker kit from speedway with Hypereutectic pistons
Vortec heads
Edelbrock Tri-power intake with 3 Rochester 2G carbs and Finned aluminum air cleaner.
Finned aluminum valve covers
Reasonably lumpy cam but not too radical so I can maintain some sort of civility and gas mileage.
or
I will be into the motor a little over 2500$
I am also going to put a york air compressor on the motor for my airbag setup...now if I can just get enough time off work to get anything done....
I ordered the heads and rotating assembly for my motor today...it was a bit pricey but relatively low budget compared to the alternative. I am following a build on car craft's website
http://www.carcraft.com/techarticles/116_0412_powerful_small_block_383_engine/index.html of their 383 on a budget. I will do just about everything they did except for the intake setup. I should exceed all the stock torque and horsepower numbers of the stock caddy motor by plenty. I did use the Wheeler vortec heads because they are redesigned to tackle some of the weak points of stock GM castings which are prone to cracking. I also went for the better valve springs so I can use the 1.6 ratio rockers for a high lift cam. This wont be a race motor so I am not worried about putting race type gear on it.
