I didn't see a spec for lifter diameter in the NHRA Technical Bulletin for a 1988 Oldsmobile with a 307ci engine, but classracerinfo.com said .842 lifter?????
On line it looks like only the early Oldsmobile's take the .921 lifters????
Have you measured the lifter bores in your 307 block????
I am just confused
