starting off i have a 89 yj with the 258 and auto tranny.. recently i swapped in the MC2100 and am pleased with the power gain but come to find out that its not exactly smog legal here in California
.. but good news i have till next year to pass smog so in the mean time i'm thinking about doing an engine swap..
my family is a chevy family since forever and i'm the first to break away and get a jeep (which i'm utterly stoked on) so i know about the v6 4.3L and i know that they produce a lot of power.. but would it be smog legal swap it in?? another thing is i'm also considering doing a 4.0L stroked and bored about 30 over... does anyone know about swapping either of these and passing cali's smog tests?? and a pricing on both would be sweet too..
