When I let my car sit out for more then an hour it takes a while to start. Its cranking but doesn't pick. When I got to start up the car about 30mins after running it, it starts up pretty quick but I here like a squeling sound as its starts up. Is the starter loose or dying on me? Or is a fuel injector leaking/ not holding pressure?

Sounds like your starter is on its way out. If you get a new one pick up the LT4 starter. Its cheaper and is a brand new unit. Cost was like $145. Most LT1 starters are rebuilt units and require your old one back.
