Are there any OEM-like replacement pistons available for early windsors? Anywhere I look I see e.g. type of pistons as attached. recommended for 302s
(available from summitracing - speed pro)
This one has about 3/4" shorter walls than OEM piston (also shown on picture). Also it has only 1 oil hole to lubricate piston pin, OEM has one additional, about 3/16 hole opposite to this one. The non-friction parts are not machined, just whatever comes out from the cast form.
It is my understanding that longer the piston, the better it sits in cylinder and less likely it causes cylinder wall wear or get stuck. Is it safe to bet on these shotr-wall pistons e.g. speed pro ZH273CP? Is it a good idea to drill another opening for oil, as it is on the stock piston?
