The reason I see in building a 370 is that you are putting rods and pistons into a 347 why not just use the iron block and get more cubes for the same price. More cubes you have the more power you make with lower boost. Its the same reason you would build a 408 and not a 383 when you buy a 4 inch crank. Thats why I would build one anyway.
