My father and I are starting the process of restoring a 9146 that he picked up 15 years ago. We are about to dive into the motor rebuild and I have a few questions, a few as in 1000 or so. We have both done a lot of research and are confident enough to be dangerous. He is keeping the numbers matching motor to sit on a shelf. We will be building off of a 69 magnesium case. We plan on going with the short stroke crank and either 86 or 90 mm J&E pistons and cylinders. Engine will have 40 weber carbs with chokes sized accordingly. Camshaft will be ordered specifically for engine.
Can any of the informed engine builders advise whether this is a good set up or not? Car will be a garage queen and occasionally autocross and driver’s ed. He is looking for 150+ horsepower.
Thank Matt
