Well, I'm glad I went with a 428 then.
Now you know you can get the same peformance from a nice 428 block that you can from a nice 427SO block (if you don't know that, take my word for it, you can). Would you rather have a 427SO over a 428 that has better performance and street manners? In other words, even if the 428 is better, would you still opt for the SO, assuming the SO is still a very nice engine?
