    Default Can't decide 468 or 496

    I am just wanting to build an engine for my 19' Taylor SS. Its just a lake/river cruiser to have fun with, pull some skiers and tubers, and make a little noise But speed is always fun, as fast as realistically possible on my small budget. I am only looking for 5-600 horse, can't afford any more right now, and I am on a very limited budget (which is never part of the equation with boats). It seems if I look long and hard enough I can find what I need for a 496 to hold that power okay. But, there's some real good 454 forged piston rebuild kits out there for pretty cheap.

    What do you guys think? I've always wanted to build a 496 and big cubes are fun! but is it really the right thing for what I need?

    How much power/rpm are stock cranks good for? what about Scat 9000 cast stroker cranks?

    I just read that build by obnoxious and it seems like a 468 would get me there, 496 would be even easier to get me there though?

    Help me oh wise ones!

    First question. Do you have any parts? And if so, what are they? That would be the deciding factor for me. If you're starting from scratch I would go 496. But if you already have a good 4 inch crank, then I would do a 468

    you might wanna try this question in the dyno section too

    I am starting from scratch, like I said I know I can find the parts if its really worth it.

    If I don't get much response here I'll move it. Thanks!

    to build a 496 is only couple hundred more if your starting with a stock bore and rotating assembly. the only thing your going to use is the block. there was a 4.25 crank and few different set of rods in the parts spam. as far as the crank, a eagle or scat cast is good for 700hp and the more ci the better. to spend that kind of money to build a motor just treat your self and spend a few more dollars and build the 496. i was in the same boat and this is what a was told and after you run the numbers your going to say why not. plus you can say you have a 496 stroke. that should be reason enough

    Do you mean a couple hundred...or a couple THOUSAND more??? Its my experience that its at least a couple thousand more to build a stroker.

    If you've got some good heads or can pick up a decent pair cheap the 496 is the only way to go IMO. You can probably pick up some ported out rectangle port heads that'll let it breathe a little bit more fairly cheap. The heads will make or break your HP.

    Default motor

    NO SUBSTITUTE FOR CUBIC INCHES. check out probe. parts all over this sight in spam. heads,intakes,carbs really good deals take your time they pop up everywhere. ask what parts you want and someone will always reply...im building a 468 (again) and 540. biggest diff in price is the heads... from 320 to 345 cc big differ in price. good luck parts hunting youll get it together. great bunch of people here.

    ha, well I guess the consensus answers my question.

    Now some questions:

    Should I go for the forged pistons or run some hypereutectics?

    Pressed or floating wrist pin?

    any ideas on a bearing kit or rings I should be looking to get?

    Do you guys have a preference on BB generations?

    either one of those motors will get you your goal, with good intake, heads, little compression and some good headers, ignition, carb. Do you want a stroker motor?
