I have a 1970 E440 HP bare block (standard bore !) and I want to use as the base platform for my 440 +6 Engine.
Aside from the timing chain cover and Main Caps, the block is bare.


Currently in the car is a 1971 G440 (Non HP) (Blue) Engine. It is running but weak and needs rebuilt.
This engine is 100% complete from top to bottom and front to back.

My original plans were to go 440 Source and get a complete kit including Crank, Rods, Pistons, etc...
I've used them before for a 500ci stroker and had good luck with them.

I've heard that the 71 G440 (Non HP) engine I have came with a Forged Steel Crank and good Rods, etc.. so there may not be a need to get a complete kit.

Question:
Seeing that my 70 Block is bare and needs everything, what parts should I pick from the 71 block as a donor and what should I go ahead and buy new ?

Thanks in advance !

Gary
