Re: What is Correct Piston for 1954 with 327 cid Engine?

"That one piston is an Autothermic brand as specified in the shop manual. It was very pitted on top and the rings were rusty and deteriorated. "

From that description i am unable to determine if the piston is serviceable or not. Pitting on the TOP (crown) of the piston is not necessarily a reason to scrap the piston DEPENDING on how bad the pits are. I can't see the piston so i can can not make any judgement call at this point.

Or to put it another way, I've built engines using pistons where a valve guide had broken and beat alot of small nicks into the top of the piston. Otherwise the piston was good. In fact i've buuilt at least 4 such engines over the years ranging from hi performance chevy engines to HD to Indian and small lawn mower engines. They ran a long time and very well with no problems.

Desireable???? Of course not. It's not a perfect world.

As for buying just ONE piston then good luck. in most cases suppliers usualy only sell in sets.

Take a closer look at the bad piston.
