just got done tearing down my new (so i thought) 500 stroker to find it had a scat crank 4.150 strk with ly rods and 30 over 400 pistons in it wich would explain why it sat in the whole. the cast piston cheepies had cracked on the oil ring lands now i need new pistons is there a good set i can use that wont set me back 600$ im on a real budget and i dont think the guy who sold it to me will cough up some doe to repair it,some help and sugestions from anyone who has gone thru this situation please. thanks

440 block or 400 block Stayng with the LY rods??

its a 440 block thats 50 over,as i was told coz it has 400 30 over pistons in it

Call the cops on that cheap cheater, at least make him sweat a little Only a real fool would use a set of stock type 440 rods with a new sroker crank You probally won't find a cheap set of decent forged pistons for your stroker deal, sorry Your best bet is to contact 440 Source and see if they can help you on getting some decent pistons for your deal

thanks im going to confront the builder with the facts and see if he's willing to make wrongs right

well that comes out to 498 cubic inches. being .060 down the hole on a 498 stroker is not such a bad thing.

Are the pistons flat top no valve relief?? (I'm guessing flat top)

Anyway with a fel pro composition gasket and 84 CC heads 10.4 to 1 compression. 76 CC head 11.2 to 1

What Kind of heads. the least expensive option would be another set of
cast pistons

Now if he balaced it (and I said if) you may be close enough to go as is but I think I would balance.

If the LY rods were not resized and ARP rod bolts added then the cost involved you may as well buy these and do it right

990 pin

Basically you got just the crank out of a stroker kit?? LY rods everyone has laying around lucky to get $50 a set.

You should go with a forged piston, new rods and balance this would require finish honing .005 more. and require the .990 pin rod

so the only cheap way to get up and running would be the seal power pistons .

the pistons are cast flat top and im useing 75cc chamber eddy victor max heads with a x-ram,thanks

Just to clear up a couple of points.....

The original 440 strokers used the 4.15 crank, LY rods and 400 pistons. That's from back in the day when any real 440 stroker pistons would have been custom and $$$$$.

Lots of engines were built that way.

Lots of sets of LY rods have been into the 10s. I bet lots of cast pistons, too.

So I don't think you got less than what you were told. It sounds like a pretty nice street engine to me.

Did he specifically tell you the engine had aftermarket forged pistons or rods? I bet you ASSUMED that, because that's how most strokers are built nowadays. I also bet you haggled on the price.

The main reason for cracked piston ring lands is improper assembly of piston into block. It's a workmanship problem, not a material problem.

R.

So your at so your presently somewhere between 11.1 and 11.3 to one assuming a fel pro composition gasket just fine with aluminum heads.



So do do it on the cheap these pistons

new rings
http://www.summitracing.com/parts/slp-e-318k30/overview/

thanks your correct i asumed coz i thought that the kit was a moscle motors or a 440 source one.

So how was the short block price?? new or used??

i paid for a new(so i was told ) stroker kit and paid about 5-or 6 thousand all together with the heads the eddy heads cost a extra 14 hundo just for the t&d rockers and pushrods wich bumped up the price.it seems that maybe this was a used motor coz i could see the factory head gasket pentastar on the block still. and i still cant cross check the cam that was in it.

How many miles did you put on it???

So 7400 all together or 5000 to 6000 with victor heads.


Check the rings for butting it's such a low buck build probably not balanced and may have put + .060 rings in maybe that's whats pulling the pistons apart.

cross hatching still on the cylinder walls. did it have steel or composition gaskets.

Pictures of everything lots of pictures?

Cast pistons, LY rods, and... TD rockers?

Doesn't seem to match up on quality and cost.

5-6 thousand total and i only put mayby 2 miles on it,yea i know i just drove it around the block about 4 times when i started to get problems. it has cross hatch on the walls and it had felpro fel1009 head gaskets

wow 2 miles either it was well used or something else hear??

Check the ends of the top to rings to see if they butted?? They will show shiny polished look if they did should be able to see.

any scrapping on the cylinder walls??

Are they real edelbrock heads or the Chinese I'm a knock offs??




all the cam lobes look OK?? Hydraulic and way to measure it take it out and measure the width and the hieght of the lobes difference may tell you a bit

ther seems to be some scuffing of the walls but looks like itll clean up with a light hone im gona check later and take some pics was told the can didnt have good readings on them like the lobes were not all the same but didnt seem like alot of wear they are the real eddy's got them from mazolinis it seems that they were not set up correctly seems that the springs needed to be shimmed and werent cozzing them to move around alot was told it could be fixed. and also the cost of the rockers were high coz t&d was the only one making rockers for this head at the time i got it

Make sure you check them top rings for butting!

what kind of troubles was it giving you?



If that's all you did everything should still look brand new.
