Need to make a decision fast 5.7/6.1/340

more potential? guess that all depends what you want in the end...

I guess what I was getting at is that I think the modern hemis can be built to much higher power levels and retain very driveable manners for less cost. The stock heads flow something like 285/185 intake/exhaust right out of the box. It takes an aftermarket or heavily worked LA head to get anywhere close to that. Then do that same work to the Hemi head and you're way over anything an old small block can do. Driveability may be mostly based on fuel system of choice (EFI or carb), but typically the small blocks take a lot of rpm to get the same kind of numbers as well, which is usually harder on parts. Not saying it can't get there, just that it sure seems a lot easier to get there with modern technology and design.
