The truck block is similar to the car block, but has some extra machining for a lower compression ratio. As such, it probably is not possible to get as high a compression ratio with a truck block as would be possible with a car block. This might make a huge difference in a race car, but for street use, on today's pump gas, it might be just fine.I would try to get it running. A running engine is almost always worth more than a non-running similar engine, since you can actually verify that it will hold coolant in the water jackets and has oil pressure. Someone will probably want the engine. I would be thinking in the $400 to $1000 range, depending on how worn out it is now. To build a street 409 out of it, I would guess that a person would have several thousand more in parts to build a good street engine, depending on what could be scrounged used at swap meets, plus whatever machining that would be required. If the engine will run, I would be most concerned that it has never cracked anywhere from being frozen or that the water jackets have been allowed to rust away badly. Good luck! |
