I started off building a Small Block LA for it. I got a 408ci Short block, Brodix B1BA assembled heads, a lunati Roller cam and hydraulic roller lifters, and Edelbrock Air Gap Intake. I painted everything, including the aluminum intake and heads, Hemi Orange (because it looks cool and I don't like the turquoise color). Right now I'm just waiting on the oil-slinger (which is one of the many parts I overlooked at first) to arrive before I can put the front cover on.
I also put together the Magnum force suspension this week and have some pics of that. It took about six months for them to get it to me but It looks pretty awesome and should help make the car handle much better.
