When i worked for summit racing I built a true 400 hp 350 for $3,000 with all brand new parts. it dyno'd at 410hp and like 380 ft lbs.. I put this in my 78 shortbed with a th350 and 3.08 gears and got 14 mpg.
gm 260hp crate short block $1600
lunati bm2 cam/lifters $150
trick flow KD 23* heads $600
edelbrock rpm intake $ 160
demon 650 carb $ 300
1 inch 4 hole phenolic spacer $ 15
holley blue e fuel pump $100
granted the heads i got at employee cost @600 but that shows you what can be done for 3k. All while backing off the timing and running cheap gas for daily driving. adding a small weiand blower would probably made that a 450hp/450ft tq motor...
