A decent read, for an article that's 6 years old.

The best is the 4G11. Strong iron block with the dual mivec head. Can't be beat.

I want to believe!!! But srsly a 4g11 is really a thing but it's only a 1.2... Did that really have dual mivec or are you just ****ing with me(us)?

Great share. I'd love to drive these back to back and test the lag.

Head flow numbers

Garbage article, head flows are backwards 4b11t flows more than 4g63 on intakes. They are also way off, no way either even comes close to those numbers on a flow bench even with porting.
