I am thinking of swapping in a 351w stroker in my 94. I have the shortblock done (its a 392). I have a comp cams 282hr I know its the same one used in the crate stroker its what I have though. I was wondering what would be better way to convert over to roller lifters? The crane retro lifters or can I use the spider and retainers out of a roller motor? also what should be the correct pushrod length for either one. I know I should measure but figured someone might know. Thanks
