If you had $2K to play with...

this is what i've got going into my motor. i haven't run it yet, so i can't say how it will perform, but i think it will be a strong runner.

used head (complete with rockers, valve cover, etc) from pick n pull $150
big valves (1.44 and 1.70?) from 'engine builder' on ebay $80
valve springs for a 340 $?
head shaved 0.090, valves seats cut bigger, hardened exhaust, valves installed $500
hooker super comp headers $450
high pressure oil relief spring $8
offenhauser intake (used) $200
holley 390 cfm vac secondary, electric choke (used) $200
mopar mild performance cam .460 lift 268 duration? (dont have specs in front of me) $200
miscellaneous fasteners, engine paint, cleaning supplies, carb rebuild kit, etc. $100
harmonic damper (see my other post regarding that debacle...) $170
all prices very approximate

also, will need exhaust setup done, probably couple hundred
still trying to source a windage tray... and stall converter

always budget more than you think you will need, cause you WILL go over budget.
