Mark,
Looks good.
Looks like you using SBC motor mounts and then adding in or building some LS1 adaptor plates?
What gear ratio are you running in your 9-inch and did you buy it built or did you buy the right width and weld on your own spring and shackle mounts?
Also, looks like you went to hydroboost due to fitment problems of a vacuum booster and the 4l60E?
I am planning a similar swap in my '59. I have a local yard looking for a low mileage 6.0L. I'd be happy with a 5.3, but the 6.0 would be a bit faster and the price on them seems to be going down around here with the price of gas going up. I have the MII front end (Fatman's Fab) and power master cylinder in stock location. I am concerned that master cyl, transmission, and driver side exhaust will all want to go in the same place.
I have been thinking about a 3.25 or so gear ratio with the 6.0 motor, rather than something like 3.71.
