Careful with that camshaft - ZR-1 Net Registry Forums

A26B · 12-05-2019

Quite awhile back, I purchased 31 LT5 engines the came out of a GM warehouse. Most of the engines were in some state of disassembly which included some loose cams with the sprocket still bolted to the cam. I put the cam in a vise clamping the hex end in the jaws to remove the sprocket/cam bolt. I didn't measure the twist in the camshaft, but it had to be in the 15~25deg range before I quit. Very spooky. After that, I would nest the camshaft in the cylinder head with the retainers & pin the cam with the timing pin. Works very well to remove/install the cam sprocket bolt.
