I have a very strange question for anyone who has ever stepped out on that very thin edge of fabrication and madman. I was on E-Bay the other day and saw a fellow that has the info on how to adapt an old SBC over to the OE style roller lifter set up. He claims that you tap the lifter valley and install three bolts that hold the retainer plate and do some clearance work around the lifter bosses and it works like factory.
My question is, has anyone ever tried this and had it work for them. Like I said walk that fine line of block destruction or backyard engineer.
