The one thing that confuses me is that it doesn't give me the correct dimensions of everything need such as the bore, rod length and stroke. I was hoping one of you guys can give me that correct information. It only tells me that I need to bore the block .060 over. The kit I found is from flatlanderracing and is made for a 454 chevrolet block. I would appreciate it if i can get the exact bore, rod length and stroke needed. Thanks.

Lets see, .060 over makes your bore 4.310. That gives 467 cubes in itself. Taking 524 cubes and keeping the bore the same, it comes to a 4.4896..." stroke, most likely a 4.500" stroke. So, here's how I see your options, since you increase your stroke by a half inch to get that cid, you could get pistons w/the pin raised by .500". This would give a poor compression height and you wouldn't likely be able to run much nitrous or any forced induction because the piston head would likely have to be thinner and the rings closer to the heat to accomodate this. Another option would be to get a set of rods that are .500" shorter, then there's the rod angularity issue. I'm not too up-to-snuff on big block aftermarket internals, but I THINK there are some rods that are .250" shorter than stock, this would mean only moving the pin up .250" and possibly being okay with your rings. Either way, you'll probably have to get custom pistons so the skirts won't hit the counterweights. Other than those options, you could always get a tall deck block and longer rods to put those pistons up there against the deck surface . But who want's to run a custom valvetrain?

One thing is that i'm definitely not going with an aftermarket block. I am most likely buying a regular 454 block from a friend or something. I just can't afford a new block. So since a 524ci comes from a 4.500 crankshaft, will the 454 block have to be clearanced for the crankshaft or what other problems might i come across?

Why not look at 496 kit, I think it will present much less in the way of trouble since you want to stay with a stock deck height.

.060 bore and a 4.25 stroke, and no clearence issues as far as I know, not to mention a better piston pin situation.

69chevy

Very possible since we don't have a block yet either way. There's just too many options to choose from .

i vote for the 496 also.you can get great power out of a 496 and if it aint strong enough n/a,give it alittle squeeze.

SprayedSDime

Yea, you probably will have to notch the bottom of the cylinders to clear the counterweights, not to mention have a "stroker" oil pan that clears them as well. I was wrong earlier when I said if you stroke .500 you move the pin up .500, it's half the stroke increase. So stroking .500 means moving the pin up .250 or .125 shorter rod w/.125 higher pin. Either way, a 467 (454 .060 over) is still killer on the streets . Just give that sucker enough dome to get some 10.5:1 compression and throw some aluminum heads on it, put down 500 tq to the wheels naturally aspirated...

I agree with the 496 also. You can go with a slightly longer (Usually +.250")then stock rod still get either pump gas or race gas compressions with regular off the shelf pistons (Depending on which you go with) I picked up a Scat kit awhile back from www.kskustoms.com good guy to deal with and a decent price. Typically on a 496 you do not have to notch, but if you go with a long and bulky rod then MAYBE, but still doubtful. Good luck.

69chevy

A 496 sounds like the best bet so far. It seems like it would be a lot easier to get parts for it too since it seems to be a popular stroker assembly and what not.

A 496 is what I plan to eventually turn the .030 over 454 that's in my 67 into. Having a connection at JE pistons that knows Hank the Crank doesn't hurt either.

I'd say the 496 is by far the most common BBC stroker out there.....4.25 crank, 6.385 rod, 4.310 bore. There are other combo's that'll get you 496" but thats the most common. There's tons of 'off the shelf' pistons available, affordable cranks, rods etc. Power can be awesome too with the right heads/cam combo. Mine makes around 850 w/ a good tune up.

Hey, I got one right!!!!! Yea!!!

LOL!!!

I may still switch to a BB, just right now I'm up in the air. I'd love a dependable 800-825 N/A.

73ss496

hey fella's i would have to suggest a 496 if your wanting a stroker. i have on in my 73 chevelle ss . very easy to build and they run very good . i dont have any track numbers for you guys but i and hoping for some mid 7's all motor 1/8 mile in a 4,000 lb car with stock suspension . the 496 is by far the easiest stroker to do . have fun and g/l with what ever you build

definetely do a 496 heck my 468 went 10.40's at 3600lbs

69chevy

Wow, put that car on a diet and it should haul....

We still haven't bought anything motor wise so things are still in the air but a 496 is starting to sound like my best bet . Thanks guys

uberLS-1

How is it still in the air? LOL
A little more encentive needed? How about if I told you that with a decent top-end package that you have a few options to have a 650-750 hp combo....ON PUMP GAS! that isn't even an all-out "Pump gas" combo either, don't even get me started on the possibilties if you are willing to open your fuel options up. There is reasonable combination's that can make in the neighborhood of 9-950 hp with race gas and slightly better if you include a vacuum pump. Ok, enough blabbering, good luck, safe racing, and above all....buy a damn big block!

69chevy

The reason it's still in the air is financial purposes. It's kind of what we can afford or how much money we can save up. We've invested a hell of a lot of money just to get the body of the car almost done so we've kind of exhausted the bank a bit. Anyways, I would actually like to see some combinations to make 900 hp on race gas if you are willing to share some.

73ss496

yes this is true. mine should be making 650-700 at the flywheel pump gas. and making 900 on race gas should be easy with a little spray

69chevy

I'm not a real big fan of nitrous even though it's cheap and can't afford forced induction so i'm trying to see how much I can make on motor.

uberLS-1

so you want a combo....that will be $59.95, LOL
a relatively easy 496 combo...
14:1 ish compression
AFR 357cc heads
ported Super Victor
1150-1250 Dominator
(Preferably tunnel ram with dual carbs)
2 1/4" primary header
Custom solid roller probably high 270's low 280's at 0.050"
"Around" .800" lift

Grant it, you could even run the 335's or some Darts and probably hit 900 with a vacuum pump...will make the power even easier on the 357's. That is about as general a statement as can be made, as I do not know the specifics of the ENTIRE set-up. If you seriously want my recommendations and help, might want to PM me, I will be more then happy to give more info.
