Description
under 10" 1: Cams for '55-'57 engines can be custom ordered. 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 Hydraulic Roller Lifter Install Kit for '87-'90 Blocks or '91-'02 Blocks can be purchased, as well as a '87+ OE-Style Hydraulic Roller Cam.

GM gradually added roller camshafts to 305's and 350's from the mid 80's forward. Camaros/Firebirds/Corvettes received the roller cams early, but many trucks and SUV's had flat tappet cams until the mid 90's.
