I've built 4 or 5 400 block stroker motors with 4.25 crankshafts with both H beam and I beam rods and two 4.300 stroke crankshafts with internal and external oiling systems, on the five motors I used a stock 3/8 internal pickup I had to grind around .030 to .060 off the pickup boss near the threaded end to clear the front rod scope
Mock up the crankshaft in your block and install the front two rods and pistons with no rings on the pistons and check what grinding, if any,your block will need scope
The stock size Mopar rods need a lot more grinding with the steel H and I beam rods shruggy

Thats good to know Cab, thanks. I'm on the fence whether to do a 470" or 511" low deck stroker for a street/strip setup. If the 511" is alot more hassles it may not be worth it for the extra 41" for a street car.
