U can easily change the lifters and pushrods in the 67 and back big blocks to the 68 up. The pushrod seat is .075 thou lower in the bb lifter. But now the aftermarket has made them the same. Kim

Thats probably a misconception that the bands get exposed on high lift cams. they should move the band up so it doesnt get dropped out the bottom! And Why the heck are the banding solid lifters anyway? There is no oil hole to unshroud....? Stupid lifter companies...what do they know ? Pshhh....I have seen that some solid lifters providers state that they have moved the oiling band down to avoid the band being exposed.
Good point, why is the oil band there on a solid flat tappet that has no push rod oiling? Do manufactures use the same tappet body for both solid and hydraulic tappets?the later lifters on that break had a 3/8 ball seat while the older ones had a 5/16 seat iirc.

take a straight edge across journals on a stock cam, note distance to highest lobe. now take that monster .630 lift and do the same...there is your lifter difference out the bore. not much eh? No matter the lift on a stock bearing cam, the lobes still have to fit through them!
That what I always thought, but you can buy .904 solid tappets without the oil band. How does that work for oiling?It’s there to help lube the lifter and the lifter bore. Kim

Just like the aftermarket deleted the groove in the rod cap to oil the cylinder walls. It was deemed not necessary. KimThat what I always thought, but you can buy .904 solid tappets without the oil band. How does that work for oiling?

Were they too low in the bores or did they travel too high? Inquiring minds wanna know.
I didn’t do any trouble shooting to see exactly what the problem with them was.
A friend had some of the “normal” lifters at his shop, so I swapped those in without even pulling the intake manifold off.
The problem was solved, so I forged ahead.
My “assumption” was that they were too low in the bore and oil was running out the bottom.
With those in the motor, it basically had zero oil pressure.
