And this is how it all snowballs out of control. Instead you could buy the 318/904 combo: add a cam, lifters, and valve springs; brass freeze plugs; gaskets and seals; 4 barrel carb and intake; 340 distributor; high pressure oil pump spring; windage tray; check the rod bearings; change fluid and filter in the 904; adjust the bands; replace the seals; up the pressure and get a 4.2 kickdown lever; get a 66 2 1/2 diameter Charger single exhaust for the original manifolds; and be done for next to no money. If you want to up the power, even more all you need is a pair of 360 heads and a set of pistons.
