Here is a Ford 347 Stroker going together. This one is going to be a low buck street cruiser, so there was no need to go for the high end stuff…..HOWEVER just as in the above engine, the rotating assembly was balanced and ALL specs were painstakingly checked, double and triple checked! First before any final machining or cleaning is done the block has to be clearanced for the longer stroke. Here it is easy to see that the rod bolts will not clear the oil pump boss nor the bottom of the cylinder.

Here I have clearanced this cylinder…this is repeated for every rod…It is time consuming and requires patience…BUT if not done correctly…….WELL you can imagine!!!!
