Im considering building a 408 for my foot brake bracket car over the winter and I'm curious about strength of block differences between the two, I am currently running a 5.9 magnum and really like the ease of the factory roller cam set up so I'm leaning that way. I have both blocks available so that's not an issue...so magnum vs LA...what say ye? Advantages vs disadvantages I'll be planning for something in the 600hp range
