Hi! Im looking back on my stroker build 440 to 493 cui 2 years ago that be a succes. I have about 2000 trouble free miles on it now. I just think of all the grining in the engine block that i have done that no one else have done when they have built a Mopar stroker from a 440 block with a 4,150" crank, 6,760" H rods. I had to grind for clearance in the oil boss a lot and also in the 440 source 3/8 oil pick up tube for a 7" deep oil pan(see added pics), in all cylinder bottoms for clear the rods and als in 3 places for the crank counter weights. Is there really so much difference in the blocks? I must have get the one really special block (440 -77) because i really needed to grind alot to get 080" clearance everywhere. Just a thought. Im really happy with the engine, its a street engine 10,4:1 with a pretty mild 231/237@050 cam, making huge torque and is perfect in my Chrysler 300 -64.
Alot of grinding work, not only the pick up boss, also in the actuall pick up tube, just happy i could keep it itact In all cylinder bottoms for clearance rod bolts
I've used both stock rods and H beam rods in my 4.15 crank 440 and didn't have to clearance the block. Infact I use a 1/2" oil pickup.
I have heard of some who did not need to clearance and some who have the same experiance i have with a lot of grinding, and all are 440 blocks with vary years, my block is from -77. So its talking for itself, its vary alot in the castings of 440 blocks.
