The last time I open up the front of the engine, the chain seemed to have a little slop in it. I thought I might replace just the chain only. Can anyone tell what I have just by looking at a picture? Also can just the chain only be bought? Seems like I remember something to do with a big block chain, but I really don't remember.

I think it's the 400 BB that is the one you want. But you should look real good at the sprockets for wear also.

This set only has about 6000 miles on it. I am a little surprised how quickly the chain developed some slack.

How little is little? Its typical for a chain to have a tiny amount of slack in it,after it breaks in.

Looks like standard stuff. A Cloyes chain should fit fine. They come in a few different grades. I'd get their best. Cheap chains do stretch pretty quickly, initially at least. Summit has the good one for $60 and the cheap one for $22, but the cheap one isn't stocked. Rock Auto has the cheap one for $15.30 and the good one for $74.

I like to soak my timing chains in oil before they are installed for the last time. The timing chain usually comes off at least once when degreeing the cam.

If you have less than about 0.2" of total side-side slack in the chain by pushing with your finger (in then out), run it. Most chains break in and have some slack pretty early on, then settle in for the long haul.

I can't remember for sure but it seems like it was moving more than a 1/2". Next Sunday when I pull the motor and change out the cam I'll take a measurement. I'll have a chain on hand though.

So it looks like I can just tell the Speed Shop guy that I need the best big block Chrysler roller chain he can get?

Id be more inclined to look for a set....or the chain that best works with my gears.

Usually the crank gears are powdered metal. I had a rebult 360 in my van that had the non roller steel gears. I pulled the motor at about 10K and couldn't believe all the slop!
