Trying to salvage a ford 302 which had a failing cam and lifter. It was full of mud, looked like grid blast stuff.
Cleaned everything and now seeing if it makes sense to rebuild it.
When I installed the crankshaft and fit the caps, with this engine I am not able to turn the crank with lot of force.
When I measure the diameter crankshaft diameter it is 2,2375" which is undersize 0,010. The bearings used are also undersize 0,01 which makes sense. When measuring the inner diameter of the bearing, it shows ovality. The max dia is 2,248" and min 2,233". This means a large clearance of 0,0045 to 0,0105" while 0,0027" is advised.
These measurements are done on the used bearings...
My feeling is that the holes in the blocked are not aligned since when the caps are removed, the crank rotates freely without out of roundness of the crankshaft journals.
If this is the case, since machining costs are such high in Europe, it makes no sense trying to re use the block.
What is your opinion ?
