'74 351w

[LX50]

Hey Guys,

I have a '74 351w. I want to convert the block to a hydraulic roller for street use. What parts do I need and/or machining?

Thanks

I converted my old 351w using a comp retrofit cam and and comp spider tray. You'll have to drill two holes for the spider tray and tap them for 1/4" bolts. Also gonna need some hydraulic lifters w/ the dogbones (used some stock ones).

Buying the $500 linked bar lifters will enable you to run a traditional cam. No drilling/tapping/etc.
