Now do you have to get retrofit lifters if you make a non roller 351 a roller..Can you not just use 302 lifters and spider and use any roller cam.I have heard you have to get the retrofit lifters...just want to be sure....

The non roller block does not have the machined groove for the dog bone that holds the lifters down in a roller block. I think you either have to use the retrofit lifters or pay for a lot of machine work. But I could be wrong.

How would you keep them from rotating?
Why the need for a small base circle cam?

Not following you here

rotating= dogbones and spider
smallbase circle to lower the lifter in the bore so they get oil

The non roller block is not machined for the spider and dog bones so how would he use them?

just like a roller block. All the dog bones have to do is keep the lifter from turning. and the spider keeps the bones held down. Or never mind what i have said and buy you a set of retrofit lifters its actually about the same price if you already have a cam. It does a will work have seen several 302 and 351w done like this.

I think what Marc is saying is that you can just tap the block for the spider and the tension from it along with the two lifters working together will keep the dogbones in place.

The small base circle cams are high if u can find one. just buy the good lifters and be done with it.
