408 or 426 stroker?

Hello,

I was looking around this site and I came across a link to a 426 stroker kit of the 360.. That's Hemi sized I am about to start my 408 project but Now I am looking toward the 426.... What do you guys think? The 360 bore would remain at .30 over but the extra cubes will come from a longer stroke... I am concerned about the block not being able to handle it ... would it be any more "unreliable" than the 408? I need reassurement lol!

Thanks,
-Jason

I say 426 just for the fact that you will be the first one running one on a bored 360. I can't imagine the amount of torque that engine will be capable of...

It won't be streetable really... You'll need some amazing cooling method in order to run it for long periods of time. I'd tell you to go for it, but I don't really know your intentions. If you want a truck you can cruise around with friends and drive fast then go 408, if you want a quarter-mile time better than a top fueler then go 426 but you probably won't be able to make it streetable.

i cant see why not. alot of time it would have to be the cam choice thats mad as to whether or not its a streetable motor or not. just stay as computer friendly as you can with the cam, and dont go with too much duration. might want something 2-3 steps up from the r/t cam. nice lift, blah blah. go with a 2800 stall converter too in the trans. i would justify the price of the 408 to the 426. see how much of a difference it is. and if its worth it or not. either way you go, it'll be a killer motor :biggthump

also read that caption on that site carefully. not all 360 blocks are the same. you would have to get your motor sinic checked and magnufluxed for cracks and wall thinkness. if the walls on the cylinders are thick enough for such and overbore, then probably go for it. cooling might be an issue. but they make aluminum bolt in radiators from be cool for our daks now, so that should nix that in the hiney. get the fan fit that goes with it too. may need a third in the front. id put on on a switch right in front of the a/c rad thingy (cant remember the name of it). have your trans cooler in between that the rad. youll probably need about 4000-5000 cfm of air to cool that beast.

I dont know if I would trust that set up to much. We just got done with a 416 stroker 340 small block at work and we had to turn the crank counterweights on a lathe to get them to not smack the bottoms of the pistons during the BDC area of the stroke. As long as Hughes did their home work and actually mocked one up and spun it instead of just crunching numbers I think you might be OK. And not to mention that you will most likely have to custom flash your computer. But hey its not my motor I say do what you want. hell they make 427s out of LS1's so why not.

I think I may stick with a nice 408 for now... that 426 was just super tempting *sigh*

Cooling and drivability have absolutly nothing to do with the crank. Drivablity is purely desided apon by the cam/CR and Intake(various parts). All of with can be worked to have a 426 that would idle like a bone stock engine, if you wanted. Cooling issued is something you are going to have to deal with no matter what engine you build, more power = more heat. They cooling capasity is not going to change, it will be the same for the 360, as it is a 360 block. When spending any amount of money on a motor it is always a good idea to have it sonic'd but as a rule .030 on a magnum is very safe. However you wouldn't want to go much more than that.

Hughes claims that the crank has been clearanced to fit, they have provided quite a few quality parts , so this one should be no different. Piston are custom, the went with a longer rod(SBC sized pins, might as well go a bit longer..6.25??). They won't hit, and will be lighter.

What it doesn't say is what kind of a crank setup they are going with,...offset ground? Stuff i would ask about.

I'd say go with the 426, had I not already bought my pistons for my 390, i'd be looking into a 4.18" crank, it'll be the same price as a 4"

I thought I'd revive this thread just to get a few more opinions... Its getting close to time for making my decision... I will FINALLY have my block here Sunday

My goal is to have a truck for crusing but be able to spank a good portion of the people around here in their brand new cameros, crown vics, etc all paid for by mommy and daddy... i've heard of people making some killer HP from a 360 so why not a 408? My main concern is the block not being able to hold up to the abuse it's almost promised to recieve... hmm, really thinking of just going 408 but the extra 18 cubes are tempting... My friend is building a 64 Galaxy with a 460 and im afraid if he builds it right, he may have bragging rights over me Cant let a ferd do that
