squeal

[1971sassydemon]

just got a 1971 demon with a 69 340. heads were reworked new cam lifters and rockers. Just fired for the first time and has a squeal kinda like a fan belt. Shut it down and removed all of the belts. Still has the same sound. Any ideas? I have not fired a new motor for many years. Help!!!

Lets hope it's a vacuum leak, because anything else with a new top end would make me really nervous.

Another question if i could. What headers will work on my 71 demon ?
. It has power steering and a 340

The noise could be as simple as, having the wrong bolt(too long) in the water pump and it's contacting the Timing Chain.

Take one bolt out at a time, and then install it back in, to keep from making a water leak.
When you find the one that has been ground on..........find a shorter one.

Wooops

Was a huge vacum leak. Thanks for the input guys.
