i have a 91 RS and i want to get the most power i can get with out going into major modifications. i really want to drop in a 400(probably bored to 406).how much HP u think i could get out of a 400 and with what kind stuff? also after i get all this power i know i will have to change the car a lot to take all of the new torque; all i know about is new shocks/struts, coils springs, subframe connectors, rear end....other than that i am clueless, will i need anything else suspension wise?

 

depands how much power you want to put out, you can get about 350 HP to still be in the using stock parts range, over that then the bills will start to rack up, just do a regualr rebuilt, some hyperutectic pistons, good bearings, decent cam and the other regualr bolt ons and you'll be ready to rock.
