Ok every one im getting closer to getting my 327 chevy into my 510 but im doing suspension right now im going to do ground control coil overs but i dont know what spring rate to use the car is street/strip and will have around 400hp any suggestions for the suspension will be looked in to. Oh and if any one has a complaint of the V8 swap i dont care this is the suspension topic so just keep it to your self thanks.
