Wanted: Piston for Chev Engine
G'day Everyone!
We've come across a problem with a Chev Engine we're stripping down and doing up to put in my Blitz; one of the pistons is unsaveable. I need a piston similar to the one in the photo below. It has the number "1632" engraved on the bottom of it. If anyone has one they don't need, preferably in Australia if at all possible, would you be so kind as to contact me? Thanks for your help!

A seller on e-bay currently has These pistons for a Chev 6, but they look different to yours. Seller has 3 sets listed, but doesn't specify if they are for a 216 or 235. Maybe a Chev specialist could chip in here and advise?

First of all, Chev never made a 239. That's a Ford. The 216s had cast iron pistons and the later 235s had aluminum pistons. I'm not sure about the early 235s. Before getting a piston you'd better make sure whether it's standard bore or oversize.

Toby, if your bore size is 3.5" it will be a 216 ..I think Im correct Mike

Piston

There are several steps to take to determine what piston you are after. 1. measure the bore accurately , ie snap gauges , digital verniers etc These engines came out as 3.500 inches ( blitz's )or 3. 5625 inches ( others ) and determine if bored out to o/size ( some piston manufactures stamp the o/s on the head of the piston. 2.Referring to the picture where you are hoisting out the engine and looking at the angle of the water pump inlet pipe I would say this is a blitz engine that originally had domed cast iron pistons and a single hole in the block where the water pump bolts up to.Check how many holes in your block . 3. Looking at the picture of the piston I would guess that it is made of aluminium alloy , so it may have been a replacement set at some time , maybe had a rebore at the same time. 4. Looking at the picture of the block with the pistons in it , they appear to be flat heads , so the replacement pistons may not have had domed heads. Check whether they are flat or not . Summary Blitz engines originally had domed cast iron pistons , were 216 ci , had single hole from water pump to block . A similar engine made about the same time had two holes into the block with flat top pistons , not many engine parts are interchangeable between these two engines. So firstly determine what engine you have. Regards Jim S.
