no, yes, yes. You need to change almost everything. And the last year for the LT1 was 1997.

I have done this swap and it was pretty straight forward. If you do the swap you dont want to put the TPI intake on an LT1 block. The biggest shortcoming of the L98 was the intake. The LT1s have great intakes and can make Horsepower across the board. I suggest that you track down an LT1 with harness, computer and all.
