but they are the same as parts interchange when switching platforms IHE,cams,upper oilpan, most sensors, you can use a rwd trans.
the fwd motors have the same cams, but static ignition is 10:1 (IIRC) instead of 11:1 (Again IIRC probably discussed in this thread too)
Getting a FWD block will cost you anywhere from $150 - $1000 at the MOST
where as a rwd block starts at $1200 and goes up from there.
in the end switching out parts like the oilpans, intake, headers, it will still be cheaper than purchasing a RWD block.
the most hp i have seen on a fwd block is like.. ~500 so i dont know if they will be as good for higher hp like the rwd blocks have been seen at
