A230s came behind big blocks as well. Your problem is going to be that it will not fit in the stock transmission tunnel. You're going to have to do some creative stretching. I plan on using a port a power on mine. It will also hit the top of the tunnel just above where the cross member is. It's not by much though and I think a creative dent would make it happen. I've tried it in my 64. It doesn't fit. So I put my A903 back in it "for now".
