65 valiant 360 turbo 5 speed

Ok guys, we made it to the beach but had a little trouble after got there, the waste gate stuck closed and it made over 15 psi boost before I could get out of it and now I have a miss on #5 cylinder, think it may have pinched a ring or something, everything else went good, it got 17 mpg and never got over 185 degrees even in traffic! Man I love the boost!!!!!
