Not only was the rear driver's side lynch pin broken, but the piston was also cracked

Does anyone have any experience with Egge reproduction pistons for a 10.5:1 1967 330?

 

And if not the Egge pistons, what pistons to keep the higher compression ratio?

 

No experience with that particular application, but I have done a couple of other Olds engines. Egge pistons are manufactured "in house" and I've found them to match the original specs exactly.

You may also want to consider JE Pistons and Arias Pistons.

 

Well, by the time I started researching the shop rebuilding the engine had already purchased some - I don't know exactly which kind or from who.

I am probably being too persnickety and controlling (which comes from a lack of confidence), but whatever the shop used is hopefully right. DAMN I wish I could perform that kind of work; maybe one day.

 

Well, ask to have a look at the part number/specs. on the reciept that they got when they purchased the pistons. There should be something there to tell you what you have.
