My first good stroker was a Ohio Crankshaft 4.25 2.200 rod size for a low deck, the second one was a 4.375 Crower lightweight with Mopar journals, the last one was a 4340 CAT 4.15 offset ground to 4.300 with BB chevy rod sizes, it is in the car now My next one will be a 440 Source 4.375 to replace the Crower in the 527 and I will have the Crower offset ground to 4.500 stroke with BB Chevty 2.200 rod journal size to go in the 4.5 bore size World block with the B1 heads
