DART BLOCK - machine main bore to take large journal crankshaft
A question? Im wondering if anyone has ever done this or if its even possible???
I have emailed DART to see what their TECH says but Im chasing opinions.
I have a DART Iron Eagle Block 9.2 Deck with 302 (small journal) mains. I believe the part number is 31384295 – 351 W Short Deck Steel 302 9.200 4.125
What Im wanting to know is, is the 31385295 – 351 W Short Deck Steel 351C 9.200 4.125 exactly the same as the other except for the difference in main bearing diameters: 302 (2.249”) or 351C (2.749”) allowing the choice of small or large journal crankshafts ?
Mine has the small journal crankshaft and Im wondering if possible whether I can machine the main tunnel bore to the larger journal crankshaft? While it will cost a lot it may be cheaper to go that route if the rest of the block casting and spec is exactly the same?
Really appreciate your tech help from OZ.
Kindest regards Matt
