I have to get a new k member but are $400-$670. I have read that an Ls1 k member would allow the 5.3 to bolt up to it. Is it possible to put a Camaro or firebird Ls1 k member into a 1994 firebird and what header would I need? Thanks
LS k-members bolt right in and since you're using the 5.3 and would have the LS k-member, any F-Body specific LS style header could be used.
