You can spend as much as you want, but if you want to get the car running with no wild mods then you will save a ton. Car $600 rust free, no engine or trans. Doner car (Z28) 1999 with T-56. 2k. JCI parts $435
$600
$2000
$435
other needed parts lets say $500
total cost of running 240Z w/ LS1 and T-56
$3535
Dont get me wong, I dont think any one here did that. I dont even want to think about how much has gone in the car already. Our March pullie were 2k alone and not to mention all the other mods done to the engine, trans, rear end, suspension, etc.
