What would it take for T/A to add two extra cylinders to make an aluminum 350 block? How much horsepower would there be to gain with the extra cylinders on top of what the V-6 guys are making now? Imagine making the block with keeping the provisions for a turbo, the 350 would make crazy horsepower I was just looking at the aluminum V-6 block and thinking how close it can be a reality, but it's so far away.
