has anyone rebuilt the bottom end of there mustang without pulling the whole engine out? my mustang is supercharged and i keep adding goodies to make more power and now i'm thinking i need to forge the bottom end and drop the compression so i dont put a rod through the block. also, how much boost and horsepower will a stock 4.6 gt bottom end handle. i am running close to 435 rwhp and i dont wanna kill the block with too much hp. what would be a good forged kit with crank that isnt too expensive? any feedback would be great.
