If you read my post, I never called you any names, Francis. The fact is airflow through the engine makes horsepower. Cubic inches determine what rpm is required to make that horsepower. The larger the engine, the less rpm is needed to get there. The smaller the engine the more rpm it will take to make that horsepower. That is a simplification, but that is how it works. I've been around class racers most of my life. They check intake and exhaust flow through the heads, some times as many as a hundred heads. Then they measure flow through carbs, then the intake. They do not worry about the cylinder bore diameter. The point was there are a lot of 318's that make plenty of HP and turn good times. I'm just a poor, country boy that built engines for people. What ever their dream was. A Vega, 170 Special to go in an early Falcon, more than a few SBF, too many SBC to count, and most Mopar engines except Hemi's. I had no problem building 318 engines, if that was what they had. I could easily get a 318 to beat 360's. Do you really think, if I build a 318 and a 340 using the same heads, cam, compression, and everything else, there will be 100 extra HP for the 340 because it has some "magic" 4+ in bore? But that is not the question here. No one "needs" a 360 with it's cast crank, offset balance and goofy motor mount brackets. I know you can't help yourself, but I could care less about 360's, and I've had them and built them for others. They don't do a thing for me, and I get really tired of people pushing 360's when that is not the question. It's not about me, or you. The thread asked about the cost of building a High Performance 318 vs a 340. You failed the test, because you didn't answer the question.
