I am totally unable to find hydraulic valve lifters for my 1955 Pontiac 261 6 cylinder engine. Does anyone have reliable information as to whether 235 engines use the same lifters? Where can I get a set of 12 and do the V8 lifters work? Lots of V8 lifters available.
Recently I read that a 261 was a stroked 235. If that is true, the lifters might be the same. Time to get out your micrometer and calipers and start measuring.
Lifters are the same . I got mine through egge machine when I built my 261 Contact Mississauga engines or R &D engines in Oakville they can help you. If your looking specifically for Pontiac 261 lifters you won’t find them as that engine was only offered in Canada as a “ premium “ engine for Canadian Pontiac’s
I got mine from tom Langdon: it appears that the 235/261 lifters are the same: see: http://www.langdonsstovebolt.com/store/#!/~/search/keyword=hydraulic lifters
I see that all 58-62 lifter passages were drilled. I also read all Canadian engines were hydraulics , no solids.
