haha i tore my engine down today found out cylinder 1 took quite a beating, i blew a hole in my piston and it melted to the side of the cylinder wall. The guy i bought it from actually had pistons from a 3.8 non supercharge engine, on my 3.8 witch is a 350hp plus engine with a competition xp hot cam, 105lb valve springs, ported heads, 3.1 sc pulley pushing 10psi boost. The motor leaned out my spark plugs were white he obviously had no idea what he was doing with more air you bring in you need to have the fuel to keep up im not to sure what imma do for that i know the stock injectors are only good to 310-320hp so im ordering bigger injectors im not sure what all id need is anyone else having leaning issues?
