i have a 01 GTP that I'd like to start modding a little. the thing is two weeks after i bought it the engine blew, the lower intake gasket or whatever. so they put a engine out of a Regal (3800 sc) that had 10,000 more miles on it. so im wondering if this could happen again, ( the clock has 91000 on it so that engine has 100000 on it). so should i leave it as is or can i start thinking about modding?
