I have the engine out of the coupe to replace the low drum and align the transmission. I also discovered that there are not any oil holes drilled for the wrist pins. Should I drill holes and if so what size do you think I should use?

Thanks,
Stephen

How many miles or years have you drove it that way?
Take a piston out, how does the wrist pin look? Oil holes could be a non issue if every thing looks good. While the cast iron pistons had brass bushings they didn't have oil holes. There should be more then enough oil splashing around to get to the top inside of the piston and coat the sides of the cylinders to get the wrist pins oiled esp with the oil ring above the pin if you have aluminum pistons.

The pistons are aluminum and they have been in the engine since it was rebuilt about 4 years ago. Two of the wrist pins are too tight so, I am going to pull the pistons to fix this. I thought oil holes might be a good idea while I have it apart.

How can you tell if the wrist pins are too tight? Does not sound like you have the pistons out yet.
