Engine builders advise..500 stroker will it match?

[cultphotos]

Hi folks,
I'm offered an complete non assembled 440 shortblock.
My goal is to build an max wedge stroker engine for the 1964 dodge.
I already have :

Max Wedge Exhaust Manifolds for Max Wedge exhaust port dimensions
3" Max Wedge Exhaust System TTI
440 Cross Ram Induction

What I can buy is this:

Mopar 440 block 0.030 bore
Eagle 4150 crank
Eagle 6760 H-Beams
Speed Pro pistons L2266F

My big question is, what compression could I generate with what head / camshaft combination?
Can this offer be used?
I would still like that the car can be driven on normal gas (No racefuel)
Any help would be appreciated
Thanks!

These pistons are advertised at around 9.2-1 using a head with around 78cc but will be around .080-.090 down in the hole so your quench distance will not be optimum. Low quench engines are more prone to ping even if the compression is lower. Stock untouched closed chambered heads run around 80cc and stock open chamber heads are around 90. I'd rather have my piston closer to the head for better quench. It is possible to run higher compression if the quench is good.

Hi thanks for the "light"
I was aiming for Alu MW heads also..
So this is not the "offer" for me I guess.

That all depends on how much you are picking the components up for. The right price buy it and sell pistons to pay for what you need. I bought an Eagle rotating assembly for $1300.00 with .030 over pistons for my 440 build. The block was already .030 so I sold and bought .060 over pistons. Almost came out even and have great components for my 440/512.

Don't know about his country but in this country, not many want a 2266 piston. I have a set that's been sitting on my shelf for 20 years and no one wants them. Same for a set of low compression pistons for a 383. In some cases you can use a low compression 440 piston in a 400 but you still need to do some machine work to it for it to work and unless you have access to some machinery, the cost goes up beyond buying pistons that already fit. These days I don't buy stuff I don't need....unless the price is low enough to justify it and I think there might be a use for it or there's a market.

Yeah, you can throw those pistons away. Besides low comp, they weigh a ton. It will be a problematic slug once assembled.

Just to give you an idea here is what I am using. I decided on Indy EZ heads for the 493 I built for my 63. Its a .030 over 440 with the 4.15 crank. I had to used these dished pistons to come out at 10.6 with the Indy heads that have a small 75CC chamber. And these are right about zero deck and have the flat so with a .039 head gasket I have good quench. It runs good on 92 pump. The flat top piston would have given me 11.8 comp so I went to the dished piston which actually put me about 10.2 so we cut the head a tad as I wanted around 10.5 to 10.8 since its an aluminum head eng. It works great and runs 10's thru the pipes on pump. Ron

Cultphotos,
Cranky gave the compression for what the piston was designed for not your application. I ran the numbers and a few things concern me. With a 4.15 stroke crank and 6.76 rods the compression height should be 1.875 with a deck height of 10.725. the compression height on L2266 pistons is 1.99. If my calculations are right unless you need to mill close to a hundred twenty five thousandths off the top of the piston for it to work. The bottom line is the piston will be out of the hole over a hundred thousandths with a deck height of 10.725. Is everybody following my math? This is correct, right?
In the old days guys would buy solid dome pistons and mill the dome off to lighten the piston. Some of those pistons had a lot of meat in the top but .125 is alot to mill. I would suggest buying the components knowing you will need a set of pistons. Good luck on your build.

Get a set of mahle pistons forget that (lack of) speed pro old outdated stuff

Those pistons are a low compression piston for a 3.75 stroke 440 which to get zero deck will need somewhere around a 2.065 CH so you're coming up short. Do you have a 4150 (astm type of steel) 3.750" stroke crank or do you have a 4.150" stroke 4340 (type of steel) crank? Do you know the difference? Do you know what the stroke is? (not trying to insult you here but those pistons don't go with a 4.150 stroke crank and you said it was "an unassembled short block")

We've been through this whole shebang on another website. It is a 4.150 Eagle crank. I think he understands that the pistons are not correct and that they will be over .100" above the deck.

Thanks for the reactions..I let the offer pass.
