    Hi, I have a 1984 Buick w/ 307. I can get a 1985 engine complete for $100. Is it worth buying and using the roller lifters?
    Thanks,

    John

    Is that 1985 307 engine an Oldsmobile engine?

    If so you will have almost twice as much in it being built as a Chevy 350 or a 383 stroker.

    They can be made to run, but expensive to do.

    Good luck!   Rolling Eyes

    The older one works a lot better. The roller cam 85+ have different heads with tiny ports. I've also personally owned and driven a few of both and the 84 and older has way more torque off the line.
