Starkoel19gmx.net Posted June 11, 2020 Share Posted June 11, 2020 Hello I own a 1950 Buick with 320ci Engine. I was always believing that it was equiped with hydraulic lifters. Now I have found out that my 320ci Straight 8 engine does not have the standard hydraulic lifters. It is running with solid lifters, please see attached pictures. As I need to change several push rods I do not exactly know if I can follow to the valve lash adjustment regarding the specs of a solid lifter engine like the Buick 40 or 50 series. Also I have already contacted oldbuickparts.com to ask for pushrods that measures 13.38 to 13.46 inches, but unfortunately they dont have them and even dont know a source to buy such. What would be a good reason to have the hydraulic lifters changed to solids? Many thanks for any help!!! Link to comment Share on other sites More sharing options...
Aaron65 Posted June 12, 2020 Share Posted June 12, 2020 You may want to give Kanter a call. I got pushrods for my 263 there, but it was back in 2007, so who knows if they still have them. Link to comment Share on other sites More sharing options...
2carb40 Posted June 22, 2020 Share Posted June 22, 2020 The profile of the cams are different. The ramp is "steeper" that the lifter has to ride on one than the other! Solids cant absorb a quick jolt of a steep ramp on a cam like a hydraulic lifter can. I see you have a broken pushrod which can be the result of trying to switch to solids without the knowledge of the differences in the cams. Just a SWAG (SCIENTIFIC WILD ASS GUESS!) 1 Link to comment Share on other sites More sharing options...

CTCV Posted June 27, 2021 Share Posted June 27, 2021 I know this is an older post but just in case someone needs the info. I had my set made by Manton Push rods. Any length and any ends you want. 1 Link to comment Share on other sites More sharing options...
