Also, the reduction of the counterweights will affect the dynamics of the engine, especially on a 4 cylinder. Could you post a picture of the crank?
Another factor to consider is the engine mounting and the stiffness of the mounts. On a FWD, the acceleration and dynamics of the body and transaxle will have and effect on the block. By the way, do you have a filled block?

It would mean a new cylinder head to go to a late style block.
I have the crank up at my machinist right now. But all the counterweights are taken off except for the second one which was left for using the stock reluctor pickup (which I don't use anyway). It looked weird like it would be way out of balance, so I had them recheck the balance. And it checked fine. It is 8 pounds lighter than a stock crank.
Block is not filled. Motor mounts are hard but not solid.
In thinking, posting, and asking about this problem. I've come to the conclusion that I'm going to use a stock crank. The crank seems to be the one difference between my motor and many others that make more power and torque than me.
I hope the 8 pounds of spinning weight dosen't slow me down much.
