LT1 IS COMMING SOON.

 

you better plan alot more time for the swap than what you think. it doesnt seem that daunting at first, especially when the engine is mounted in the car and ready to go and you think the wiring is finished, but itf wont fire. then you realizes you still have about another coupla days of work before its ready to go. give yourself more time than you think you will need.
