So I'm in the middle of my first rebuild and I am considering swapping the solid lifters that are in it now for hydraulic lifters. It's a 327 that will only be driven around town and some on the highway, no track . It has a 350 turbo and 3.08 gears. My question is, what all has to change to do the swap? I assume cam , lifters, pushrods, springs. Does anyone out there have some good ideas?
