I'm beginning a rebuild on my 8ba type V8. I picked up these NOS lifters a few years ago and may want to use them. I believe they are for earlier V8's. Dimensions appear to be the same....
Aside from how they look, are there any differences?

Those are stock cast iron lifters.
They are ok for a stock engine.
You should use the hollow steel ones for a performance engine.
They can be recognized by having ONLY two 5/32 holes in the side.
If you use the ones you have, be sure there are no rust pits or corrosion
on the face.
Those lifters are for the early mushroom tip valves used with split guides; I've never used them with 49-53 valves upon the advice of others. There is concern of the smaller contact area of the late valves accelerating wear or punching through the early lifters. I have disassembled engines that had mismatched components and there was a definite recess of the contact point on the top of the early lifter. Spring pressures, r.p.m. and valve float all enter into the equation but I'd recommend matching the lifters to the valves........I.M.
Your right Pete, those are cast iron not hollow; my advice is for hollow non scalloped lifters...... eyesight is not so good anymore.... the weight of those would be my only concern......I.M.
Yes they are hollow, as Pete says, there early cast iron, They quite using them I think in the late 30's and went to the steel ones, I've seen a few of them broken. There 1-720 length same up to 50 Ford. Yours are new and should work ok on a stock engine with stock valve spring pressure, That's about 42# seat pressure. I wouldn't use them in a performance engine. Walt
