89 360 vs 71 360

Assuming their not offset lifters , why would it make the pushrod hit one way or another ??
Still clear as mud to me , and why would the link bar be any closer to the "top" of the lifter bore / one way ore the other?
I can see the links hitting the block on the cyl side of the lifter bore.
I RAN A HEMI WITH THE LINKS ON THE BLOCK/CYL. SIDE FOR 14 YRS. , AND HAVE THEM ON THE GALLEY SIDE ON MY 440/505 . ????????????????
Excuse caps !!
Is the lifter at such a drastic angle on small blocks ?

Yes. A 59 degree lifter bank angle was for the Poly 318. The cheap asses at Chrysler decided that the RPM for the LA engine would be low enough that they could save money and use most of the 318 Poly core boxes.

And that's how you screw yourself. Didn't matter until Pro Stock started and RPM's started going up. I wasn't afraid to shift at 8800 and some times at 9000 with a 59 degree lifter bank angle but I had my geometry dead nuts on, I only used 5/16 stem valves and the intakes were titanium. I also had at least 340 pounds on the seat, 3/8 X 7/16 double taper pushrods.

But yes. The angle is that bad. And you can't use inboard link bars on a 59 degree LBA.
