Having finally managed to get my finances in order, the option of finally getting a big block into the Fury is drawing closer and I'm just looking for a little input from those who have been there. The lil 318 is great for cruising around in but just has too much trouble getting out of it's own way. The plan so far...

Stock 400 block/crank/rods.
KB240 pistons
Lunati Voodoo 301 or 302 hydraulic flat tappet.
452 or 915 heads? Mild head work? Stock valve train.
.020 head gaskets or ?
Double roller chain.
DP4B intake manifold.
71 440 auto thermoquad or ?
MP electronic ignition.
Aluminum water pump.
Stock oil pump.
Stock C-body oil pan/system.
Windage tray.
Stock fuel pump.
Stock rad & cooling system.
HP exhaust manifolds w/2.25 exhaust/Dynomax turbos.
Warmed over 727/2500-2800 stall.
9.25 rear w/3.23 sure grip.
28" tall tires.
Car weight approx. 4000 lbs.

Certain things I already have, like the rear, carb, oiling system, cooling setup and an NOS 400 short block still in the crate coated in cosmoline. I HAVE to stick to minimum machine work, because I don't want the money balance to crash again. So, thoughts/ideas? A ? above means if there's a better option, I'm listening. I'd love to get into the 375-400 hp range.
