Vette man! 84-91=SBC
They can go 200k+ miles when taken care of. Hell I have a customer that has a 90 with 250k on his car. On the 2nd motor now though. But first motor last well passed 150k
And hey its a SBC! They make shit loads of parts for em. Me personally id be getting a 91. had the best dash setup, still an L98 Motor. had the zr1 style rear bumper.
