I have a 87 Elky that is in very good shape. The only thing I am wanting more of is horse power and the old question arises -- cubic inches or ? stay with what you got. In this case I have a V-6 4.3 engine. It is pretty solid but...I am on the road a lot and sometimes I need more power when passing in a hurry. I am seriously considering an engine swap to a V-8. Any suggestions? I am in Pittsburg, Ks. and would consider a professional work shop as time is a factor for me.
