Hello,
My name is Marco and i live in the Netherlands so that's why my english is not the best.
Anyway, i've got a 1966 Plymouth belvedere with a mopar 400ci in it. Stock it seemed to have around 205-250 hp, because it has pretty thick wear ridges i'm planning to bore it 0.02 inch over so i can install the KB240-20, this will increase my compression ratio from about 8.2 to 9.5. Does anyone know how many hp this will roughly gain me?
Best regards, marco
