Thanks Chuck,
Is that a hydraulic roller blk, like a newer 302. I'm just wondering if the early 289's and 302's also have .875 lifter bores. I know the early rocker arms interchange.
I'm really confused on these lifters that i have the tiebar buttons have vertical flats so the bars can be changed, so i guess my best option would be to buy a set chevy tiebars from Isky in order to use/sell this lifter set.
Thanks again for checking.
Zip.
