I know this is an old topic but I am new to this group. I recently(3 month ago) purchased a 88’Rotus R8, the first production model. This is a lotus super 7 styled car. My father worked for Rotus so this car is a dream come true for me since I grew up in the factory playing with these things. So my car has a 1962 Buick 215 built by D&D. Sad news is it was driven and parked about 15-20 years ago by the original owner who fell ill. His family found me and I picked the car up to find the motor not wanting to turn at all. I had stripped completely down and found 2 cylinders were fairly corroded. After 2 months of being patient with pentrating fluids I finally got the pistons moving and am in the process of removing the pistons and crank. From my caliper readings I believe my engine had been bored to .030” over. With the little bit of pitting I wonder how much I can safely go with another bore. I find oversozed rings up to .060 but I am not sure what would be considered the limits of the bore. Can anyone help me out? If it’s able to just get oversized rings this thing will be completely gone through and have everything soec’ed and replaced for many more years if reliable service. If not It will deeply saddens me to have to possibly look for a rover replacement. Thanks in advance.
