Modular 5.4 vs Dart block Winsor

Inch for inch, I think the mod motors are pretty darned good. They are an excellent option for people who want a good solid crate engine that starts when you turn the key, will get the groceries on Friday, and streak down the drag strip on Saturday.

If you want big power numbers, it seems that you need forced induction. Blowers seems to be the most popular in the US - probably because of the ease of installation. But there are some turbo kits available.

However, there is one important consideration - heat. I'v raced with a few of supercharged cars - a couple of blown Mustangs, and and a blown Corvette. They are really fast for 2-3 laps, and then they're done. They heat soak and the computer shuts them down. OTOH, my NA stroker is making the same lap times at the end as it is in the beginning. There's a lot to be said for that.
