Not for nothing, but you should keep the 96 cavalier and save your money for a sweet LT1 or good LS1...My current car is a showroom conditioned 1986 carbed 305 (Z28) and the insurance is a killer...unless you have a wealthy budget to trade in or buy the IROC throw a used 350 in there (unless you have 3 grand to spend on a new 350 HO) then 3500 isn't worth it at all especially with the raised insurance...save your money and enjoy the better engines...good luck
