double roller timing chain....?

[squeek360]

building a 76 360 that currently has a single roller....does any one know if the mopar performance double roller p/n P5249267 will work on an LA 360? or is that chain just for the magnum engines? Thanx

if not, does any one know where I should be looking to get an LA engine double roller

It works on both.
Just so you are ready for it someone is going to tell you to also use the chain tensioner because as the chain wears the timing can move around without it.

Pretty sure this is Jeep magnum stuff on my LA block.....

You should consider using the tensioner.

Yep, the 4.7 v6 tensioner, or the more expensive Mopar performance exact same thing.
Strike that it's the 3.9 tensioner not the 4.7

I thought the 3.9 tensioner was the one to use.

You are correct, I got it mixed up with another motor, sorry.

used the same tensioner..together with a cloyes double roler chain... but the cahin touched the fuel pump lever slightly...so I had to modify the lever arm justa little... now the combo works fine...

Now I'm going to have to look at the fuel pump arm on that engine and see if it rubs..... I used a marine pump because it has the nipple for boost referencing....
