Well, I picked up another complete 300 so I find myself rich in parts and have decided that stroking to 349 will incur a large and unneeded cost given my application. I am using the stock crank with late 350 rods on my 300 build. Silv-O-Lite HC3156 are 3.953 bore and would end up .008 below deck at the blueprint height. Plus, the rods only need honed .005 to fit the pins and cr is around 9.5 with the dish. Obviously this is geared toward a more street friendly engine with minimal cost. In my mind the advantages are a better, lighter piston with a better spring pack; better rod ratio; and stronger rods. Cast 300 replacement pistons are $360 from Summit, and the pistons I chose are $150 for a set of 6. I have looked high and low for info regarding oiling mods for the SBB, and really only found drilling out the oil pickup passage and front cover. I read some great articles on BBBs, but what really carries over? Also, I realize bearing clearances are crucial. It looks like one of my cranks will only need a polish, so I'm assuming just picking up standard bearings will be the way to go? Or do you really need to get oversize bearings and grind the crank to proper clearance? The reman 350 rods are on their way, and my plan is to finish the oiling mods on both blocks before taking them to the shop. That way if the first one doesn't check out they can move right on to the second. Thanks for the help!
