Rockers ( oh its WORSE) assembly.

[mally69]

Pistons 60 over $53 each = $424 + $25/ hole = $200                200+424=         $624  sonic check ?
Pistons 40 over $53 each = $424 + $25/ hole= $200 + 135 for the sleave total = $759
New block ah guess about $700 + $25/hole= $200            $ 200+700=              $900  give or take
Custom Pistons 50 over   + $25/hole+ $200

  Dam it.       Im fine just thinking..

[FLG]

Alright, maybe i was a wee bit off...but regardless i think it might be worth the extra cash to go with a new block. And if you go with custom pistons im sure its going to run you the cost of the new block with the old stuff. And you might be able to find a pretty good deal on a block.

I am thinking the same about the custom pistons. I never bought a set or looked into a price but I am sure they would be costly.

Doesn't 440source offer a stock 440 block piston in a .055 over?

To low of compression

[BrianShaughnessy]

Custom Diamonds run around $700ish...    I got mine from Dram.    They have a stock pn that runs 10.0 with 84cc heads at .030 over (52001). 

Aside from that...  2266's generally sit about 90 in the hole.   Where are you getting a 5 in the hole spec?

I switched to Comp Magnums a long while ago after I made the poor decision to use CAT rockers (ie: chinese garbage) and they seized and bent up valves on my new Eddy heads at the time.    At that time I swapped the 2266's in my block to 2355's.   That combo is still in the car until the new shortblock gets done. 

Sorry you ran into problems...

To low of compression

To Low... depending on your final deck height and your choice of a flat top or -4 cc piston, you should end up between 10.0 and 10.8. Do you really think that even a 0.8 compression change will make that big of a difference in your performance? Find what works to solve your dilemma in a cost efficient manner, and don't sweat the little things. The difference of a couple of points in compression one way or the other will never be noticed in a street car. You set your goals before you start, and then you do your best to achieve them. If you get close, you've done well... If you actually get there, and you still have money in your pocket, you've done exceptionally well.

Keep looking... but don't worry about it if you can't find the perfect match. Just get as close as you can... without braking the bank.

Mally I was in a very similar position you were in.  I did all the cost pros and cons and it was still better to bore my block 50 over to clean it up, but as I said I did the sonic check first,  I think this is a must for your block.  It doesn't matter if you going looking for a new block or not you still have to inspect the blocks for buildability.  My plan would be to sonic check, if good take it to 50 over, square the deck up but don't take it down anymore than you must to achieve square.  Do the math to calculate your desired compression depth and order custom Diamond pistons from DRAM.  Then build and blast!

PLEASE PEOPLE DO NOT BASH 440 SOURCE, THAT IS NOT WHAT I AM TRYING TO DO .................. They DO NOT sell junk Everything has been perfect that I have bought from them.

thats pretty funny ? you have a boat anchor you just pulled from your car because of the rockers you bought , but then you say everything is PERFECT

i can't see how you are happy with the outcome to this point ? i'd be looking for the costs to restore your shortblock to the way it was , but then again your mistake was running those rockers after the first one failed . if it were me i would have sent them all back and bought something else ...

actually if it were me i wouldn't have bought that garbage in the first place ...

great first post eh  

[mr. happy]

now that i got that out of my system 

what year is this 440 block ? you really need to sonic check it FIRST before you even considering taking it to .060 . i had a 69 HP block done last year that was at .040 and it really needs 4 sleeves , core shift in the center of the block . its ok for a trailer poodle , but to bore it further its going to need at least 2 sleeves .

how many miles on that current block and was it honed with a torque plate when it was taken to .030

you have a numbers of options , some $$$, some not so .

[firefighter3931]

This is what would happen to the harland sharp.  I could not figure it out there is not a mark on them.

That doesn't look like a Harland Sharp rocker to me ? 

Fwiw, Harland Sharps work fine with Roller cams as well as flat tappet grinds. Usually when something like that happens it's because of valve float or metal fatigue.

If properly set up a Harland sharp rocker will give you years of trouble free service.

Welcome to the site!!

I have HS rockers running on a solid roller cam with 650 lbs on the nose.  IMO HS are one of the top rockers out there.

#1.. What I was stating or ( meant ) by that was, everyting I ever bought always FIT as I was told when I bought them. I didnt say anything about the durability until they broke.

I am going to Bore it 40 over and get a sleave or 60 over, I haven't decided yet. The block is a 68 block. And I called speed pro and they told me that with the piston that I mentiond will get me 10.5 compression with the piston 5 in the hole with 40 over, and it will be 10.7 with a 60 over piston. Where did I get those numbers from??  That is where I am going with the deck height. I only had about 2 taken from the block before which was factory height before the first cut. As for using a torque plate the first time it was machined,  I would say NO it wasn't used. But I have a torque plate and I will be useing it when this gets bored. I have a total of about 3000 to 3500 miles on this motor since the first rebuild. I am not happy about this at all, but shit happens and you have to deal with it. As, far as getting my block restored they probably won't go that far, and I didnt ask. I was just happy enough that they gave me a free head and gasket set.

Oh and ((( actually if it were me i wouldn't have bought that garbage in the first place )))
Then why didn't you step up and buy me a good set of rockers then. At that point, maybe I never would have thought this would have happend. I am sure you bought something and have gotten screwed before. Hind site is a wonderful thing isn't it.

There now that I got that out of MY system

The price is going to vary from one area to next anyway, so you may as well just start calling around and asking for yourself

I looked at the wrong combustion chamber size, sorry about that . I called 440source today about pistons and they gave me the final compression ratio would end up being 10.3 with my specs which is clsoe to what I am looking for.

[mally69]

These pistons are the ones that I am looking to buy one of the 2.  And is it nessesary to have the valve reliefs? If not then Ill get the flat tops with out the valve reliefs. These are both decently less money than most even if they are heavy, they are close to the weight of my old pistons so balancing will be a bit easier. Also I wont have to change the factory pin with these pistons.

What is an average cost to have a block sonic checked.

i can understand why , to a point , you didn't think there would be an issue with those rockers but the source rockers look too much like CAT rockers and most people by now know that most of the CAT stuff is questionable at best , when you had the first fail you really shouldn't have looked at it as a FLUKE . as far as shit happens  way of looking at it , i find it amusing that people flock to the cheap chinese crap because its cheap but many times you end up spending more when you have to redo it .

i like to ask ... why is it people can'rt afford to do it right the first time , but they can afford to do it over

that aside i would go .040 and sleeve that hole  , sonic check depends on how highly the shop you use thinks of themselves , i have 2 shops local that i had a sonic check done , one place charged me $150 and only gave me the thinnest points and didn't even say where it was , second shop charged me 100 the first time and 70 on the second one i had done , but i didn't get any right up on the second only that is was good 

any performance build should use a torque plate when the cylinders are finish honed , thats if you want round cylinders when the heads are bolted on .

You know, this product is apparently flawed, and it's terrible what happened to mally's engine.  I think some complaining about the product itself is certainly acceptable under the circumstances.
However, the attitude in the statements above is one of the major reasons people stay away from moparts; it's much more popular and tolerated over there.  Let's not bring that crap here too.

If you look at the specs... the 2266 compression distance is 1.991.   The 2355's is 2.061.    The 2266 sits down in the hole and doesn't need valve reliefs.   It's a great blower motor piston or a piston to be used with very small close chambered heads.   You have neither.

I'll second that... Right or Wrong, I have little tolerance for it...

my goodness ...

this board and moparts has more in common than you want to think , or admit  

[Steve P.]

Every board has it's ups and downs. We are just trying to limit the downs. We enjoy our family and encourage all to treat others the way you want to be treated. There is just no sense to degrade anyone or try to bash their decisions. Most points have been made on the rockers. Mally is bleeding now. There is no sense in twisting the knife.

We welcome you to the site and hope you will be a positive member. There is much knowledge here and will always welcome more. Take a look around and enjoy.

Good thing you pointed that out. That piston won't work for me. Ill be going with the one with the valve reliefs  .
Thanks guys for helping to keep my post in good manners, and also help me pick the correct parts. I appretiate it. Ill post some pics as soon as I can.
