5.7 timing question

[sleddinskeeter]

putting a fresh .30 over with edelbrock intake shorty headers and rv cam in a 93 gmc 5.7 wondering about the brwn n blk wire disconnect before cam breakin or after thanks??

This may be too late, but for cam break in, I would leave the wire connected. You just need to get the timing close for the break in. You can set the timing later.

thanks for replying no you are just in time do you know the location of this wire??

On my 90, it is located under the black cover (power distribution block) on the firewall. On some models it is located near the ECM inside the passenger compartment.

Always check with your cam manf for breakin procedures.

U tube has a video on cam breakin in the engine department of these links.
