I am looking at this cam and wondered if it can be used with MP stock style rockers, I have a stock 69 440 with the stock pistons down about .060 in the block and stock Eddy alum heads.
in the link below they put one in a stock 383 and used stock rockers so I think it would work in a 440 as well???
what do you guys think?

I wouldn't use stock rockers I have one of those cams in a motor I built and used for dyno testing, I used a set of 1.6 ductile iron rockers that RAS bushed, changed and corrected the ratio on, that motor worked real well with those parts on it I'm sure you can't control the lifter preload accurately with sloppy stock rockers and pushrods

ron, is this for the race truck ? are you going to deck the block or shave the heads to up the compression to around the recommended 10-1 ?
yes this is for the race truck, I have a 69 440 that has only 60K miles on it that was in my 63 wagon, it is in good shape and I plan to use it the way it is(no rebuild)
just put the eddy heads on it and a cam(I have a 509 cam but thought I would like to run this comp cam)
I would like to run it with stock rockers to keep thing simple and easy to maintain. I have a 493 kit for a 440 that may end up in the truck
I just wanted to know if anyone is using that cam and stock MP rockers and how it works, I already have the MP rockers. Ron...

Do not see the strenghth of the rocker being a problem mock it up and see where your preload is at if its to much shim the shafts with shims from mancini if its not enough use lash caps or longer push rods. they may not be acurate in raitio and you may have to move them around to find the best preload for each lifter but i do not feel with that cam durability is a problem check all clearances coil bind ect and go. or spend more for a small return on your aplication.

years ago I ran a couple 440s with the 320 Isky cam, that cam had 320 duration and 525 lift and I liked the fact that I could just put that cam in and run stock rockers and never had to open the valve cover up all season(I really don't like adjusting rockers).
I planed to run the 509 cam that I have with the MP stock rockers but liked the specs on Comp cams XE285HL and when I seen that articular with the 383 they put stock rockers on with that cam and got 450HP out of it with stock heads I thought a 440 should be around or over 500HP with eddy heads.
thanks guys for the ideas and opinions, guess I will have to think about it a little more. Ron...
