Help me get into the 12's for cheap

-junkyard 360 magnum swap. Buy the motor from Pick N Pull for around $250. From what I've read it sounds like I would have to spend close to $2,000 with the new heads, re-ground cam, oil pan ect. It's kinda more money than I want to spend but it should create enough power to get me into the 12's.
Here we go: A stock 360 a body oil pan,E.Q.,heads,30 horsepower across the board over stock Magnums (stay 1.92 valve.). If you order E.Q. heads,buy the ones with the L.A. head bolt pattern. Have your stock cam ,reground. (Oregon Cams,keep it under .510 -.520 " lift.(valve retainer to valve guide possibly). All else ,good valve springs are needed here. I recommend asking spring pressures & installed height, upon initial phone call/email. Ask lots of questions here,before the goofy sales pitch.
