Factory roller lifter into pre 87 SBC. Conversion
There is a guy on ebay that sells info on how to fit factory style Hydraulic lifters into pre 87 small blocks.
Has anyone done this. I figure it would be about $100 cheaper than retrofit lifters. And Id feel safer with GM units.
here is the link

There are many 1 piece blocks that came with flat tappet hyraulic cams that are this way.
Without extensive mods like welding bosses to the webbing, the factory lifters probably cannot be made to work in a pre-86 two piece block.
I would be leary of this, esp since he says all you need is a die grinder.

I'll bet most machine shops could mill them though.

That's cool, even though I have a 88 block, It's good to see some backyard engineering,
