    2: The '87+ Chevy Small Block received provisions for roller lifters. Most '87 - '93 GM cars came with roller lifters, but most '87 - '95 trucks came with flat tappet lifters in roller lifter style blocks. If a roller cam is desired and your block has OEM-style roller cam provisions. COMP Hyd. Roller Lifter Install Kit for '87-'90 Blocks or '91-'02 Blocks can be purchased, as well as a '87+ OE-Style Hyd. Roller Cam and '87+ OE-Style Roller Lifters. Roller cam conversion in pre-'87 blocks requires Retro-Fit Hyd. Roller Cam and Retro-Fit Link Bar Lifters.

    3: Many OEM EFI systems cannot be tuned to run well with certain cams. Before installing in an OEM EFI engine be sure to check with a competent tuner.
