<FONT size=2>I have decided to swap out my 4.6 GT engine for a Holley 5.0 HO race engine. I first saw the engine when I helped my friend make the same modification. The engine is rated at 350+ hp, which will increase my rwhp by atleast 100 horses. I am planning to supercharge this engine, and other various modifications(cold air intake, full exhaust, etc) Would there be any problems if I got the engine professionally installed? I am not that much of a mechanic, butI know I am good with basic engine stuff, so should I install the engine myself, or have it professionally installed?</FONT>
