Replacement W head?

One of the bigger concerns is the lack of aftermarket, or R3 blocks. Once you get into maximizing the potential of an offset rocker head, you have crossed into the 650 plus HP zone. At this point, one better have the block to handle this type of power.

Although most of us on FABO love our LA platforms, this is another reason why the Gen 3 Hemi architecture looks so appealing. Stock Gen 3 Hemi blocks are good for 1000HP and stock heads flow better than ported W2's. Don't even get started on a cost by cost analysis, the old architecture loses badly here also.

Just opinions from a W2 user.
