| Re: 89' RS 9C1 LT1/T56 swap questions? 1) Im not sure but externally the LT1 is mostly SBC so anything that came off a 3rd gen V8 car should fit it including headers. Bear in mind that LTx cars use a D port so youll need headers that are 1 5/8" or bigger or the special D port hedmans
2) You can modify yours or fab something up. Its not very hard
3) Stock will fit fine
4) LT1 style T56's should have a sealed master/slave unit, so I dont think you can reuse the 3rd gen piece
5) The intake choked 305's. use it if you want, but itll be super restrictive |
