im buying a 1971 LS5 automatic, its red with tan interior, rally wheels, it looks pretty good. but, the LS5 is long gone and thers a 1967 427 in its place, the seller is claiming that its an L88, i have not confirmed this yet. i am wonering if the value of this car is hurt because the 454 is not in it, though a better engine is in it now and possibly the L88 which would be a much better/more rare engine than the LS5. any opinions on this?
