Well here is my take on the whole thing.

The modular engines are the greates engines that ford has ever built. The blocks are rock solid - good to well over 1000 hp. Many come with forged cranks good to the same amount. sure some engines have crappy rods and pistons but that has plagued ford for many years. Also the parts interchangability of the modular motors is great! Basically you can put whatever heads on whatever block you wish and it will work. That is why they are called "modular" These engines are silky smooth from the factory and make great power - with only gears you can run around ls1's all day - even with the p.i. 2 valves. Plus the new Cobra engines are the greatest engine ford has ever built! over 400 hp from the factory with only boltons away from 500! Amazing! try that with you old 5.0. Heck try that with an ls1 and its guts will be all over the ground! If you put a blower on an ls1 it is a nightmare! the high comp. ratio makes these cars a ticking time bomb! plus fragile rear ends and it is not a good situation.

Anyways, that is my rant for the day.
