360 stroker, cylinder wall thickness
This story is still not finished...
I ended up not using the block after all, since I already had the 4.030" pistons and eventually gave up trying to get them exchanged for 4.060".
Instead I found a new block. This time a "pre Magnum" from -89. I also consider the roller cam a bonus.
To make sure it was OK, I did the same measurement as previously done on the -71 block.
I also found it very interesting to check if the old myth actually was true, were the -71 - -74 blocks really cast with thicker walls??
The results can be compared in the pictures. Keep in mind that the -71 block was already 4.060" bore when measured, and the -89 block still stock bore, so to compare, the -71 figures must be increased by 0.03" or 0,76mm
