how low can a stock s10 go?

[JohnnyG.]

ive got a 92 s10 with the 4cyl. and want to do the frme swap and put a 54 chevy truck on it, but use all of the chassis of the s10. i am curious about how low the frame is in the cab area when at the lowest drivable position. im making a truck with out running boards so the bottom of the cab is the bottom of the frame and im looking to be around 4" from the ground. i just want to know if im going to have to channel it or not. thanks.
