Retro Fit Lifters Questions on Cam and Rockers.

why don't you call Comp and ask them? Thats what the tech line is for.

You are really limited to cams using stock type lifters + cams are expensive. Crane retrofit lifters allow standard cams to be used. Most hr cams are disigned for 302 ci which will work, but if you build that nice a motor, go custom.

agreed.....to further explain, note that Crane makes a link-bar roller lifter that allows the use of a standard base circle cam in the non-roller blocks. You do not have to use the OEM style spyder and dogbone setup with the link bar lifters. It is only when using the OEM style late model ford hyd roller lifters with the spyder that a reduced base circle cam must be used. The selection of reduced base circle cams is rather small, and most are pretty mild because the camshaft itself is too weak to support aggressive lobe designs. The preferred setup is the link bar roller lifters (between $350-400 a set) and choose from the wide selection of standard base circle cams. Whichever route you go, make sure to use springs that match the cam, and make sure they are at the proper installed height.
