You guys have discuss a bunch of the keys, but I have some to add.
Check out a HP/tq curve on both engines. I have one one YouTube with the 250 dyno run. The 250 puts out more tq at lower rpm.
The 250 really does not need the added cost cost of roller cam and lifters. Use the money on something else. Like rods.
