Very dumb question, 440 timing chain tensioner??

No no I went with a double roller set up, and yah the dizzy bushing came with the machine work, no need for fuel rail cuz I went electric,and went with a billet seal holder cuz the old owner lost the original, just the timing and cam cover through me through a loop

There ya go!

Little off track, but helped a buddy years ago...on a Toyota. Good thing he was a friend, otherwise hell no. Deal is, since he had over 250,000 miles on the thing, he figured it needed a timing chain. So, we dug into it.
That dang thing had (stock) a double roller. Still in great shape, just like it had been put on new! That was enough reason why it's the only thing I use. Surprised the heck outta me.
