I bought a new cam and lifters to put into my 261 rebuild. I opened the box that the lifters are in today and have been told I have new hydraulic ones. I thought I ordered solid lifters. I've been reading the old post and have read that the solid lifters after '55 were changed and "look like" hydraulic lifters. My motor is a 1957. So how do I tell for sure? Sorry, for dumb question, but this is all new to me. Could it also be that the cam I purchased needs to have hydraulic lifters?
