I recently did an LS1 into my Studebaker. See the project journal link in my sig. Alternatives for the harness and fuel delivery are www.speartech.com and www.tanksinc.com. S&P and Rock Valley are awfully proud of their stuff. The issue with in link pumps is noise and reliability. An intank pump is cooled by the fuel it sits in, the inline pump does not have that benefit and evey one I have heard is noisy. The LT1 swap will be way easier than the LS1 as you will not have mounts or exhaust issues.

I think it is a great swap.
