If you want to go on the cheep, check the above website for modifying an LT1 intake. I did one for about $200 total. Lunati has a 220/228 Voodoo cam for about $120. Keep your heads, replace valves with swirl polished valves and get the correct springs for the above cam.
This can keep you busy for a few weeks but you will get 350 HP with a low budget. Chip tune, raise the idle 100 rpm.

Do a little porting, gasket match and take a little out of the bowl areas. Get a book on porting.
