Small block cam thrust plate bolt with oil hole

Well here is the easiest way to show you what I am talking about.

Pic 1 is the front an back of the old plates and the way they were bolted on 4 bolts . The bolt with a hole no rear oil slot on back of plate for the cam. NO GOOD

Pic 2 Is the latest from mopar to try and keep their junk chains tight through warrantee Two bolts. not even a place for the lower bolt and drilled a hole in the oil galley cover. Two bolts held in place and the tensioner kept chain tight as it stretched. Only to prolong the junk to fail NO GOOD

Pic 3 is the best method. The Method used by mopar in the early 90's when they went to the cheaper chains and they were giving their junk chains more oil. they couldn't make perfume out of ****. But They did oil their junk chain better. Also note the oil slot on the rear of the plate to keep oil on the plate for the roller cam riding on it now because the cam was not being pulled rearward by the tappet lifters . Still only two bolts held it in place.

Chevy motors do not even have a cam plate holding the cam in. It is held in place by the rotating lifters.. Once you remove the Dist. and lifters you can pull the cam out with the top gear on it. Their roller cam motors get a button on the cam that rides on the tin cover to hold it rearward.


So on mopar you really don't even need the plate except to cover the galley holes and make make up the difference they didn't design in the block.

The 3rd pic is the way to do all small blocks. It oils the chain the best . You do not want the tension-er unless you go super cheap on the chain.

But definitely pic one is a No No as far as needing the 4 bolts .That bolt with the hole in will ruin the chain just as it did the one you took off. That hole only gets oil running out of the top of the motor with gravity.

So,Find a dripper and use the upper right and lower left bolt as pictured. You will thank me for this info. Now if you still want those bolts with the holes in you all are asking for just send the money so I can go eat while your all screwing your self. I can have the guys drill these by the hundereds. After I sell the ones I never put back in for 20 yr's.

The last pic the slinger throw in the garbage for performance motors. Get a 90's or billet timing cover .
