The LS1 to Chevy SBC mount adapters that bolt to the block
A fuel injection gas tank and electric pump
Some rewiring
A transmission from a similar year car so the computer can control it and also to match the bellhousing bolt pattern. (you could use an adapter but you'd still need to figure out how to cut that part out of the computer if you used an older transmission)
Proper fuel lines
Steering pump adapters or custom lines
VATS eliminator
That's all I can remember right now
