thanks you!!!! i started reading this tread and was amazed that people thought changing rods changes the stroke.D.Hearne said:Using 302 rods on a 289 crank nets you nothing but lost compression. The 289 rods are .060 longer than 302 rods. And that is if it would be possible, doing this with stock pistons also results in the crank counterweights hitting the piston bottoms.
If all you think that combo you've built is 400 hp with a blower and NOS, you've still got a lot to learn. With what you've got there, it ought to be hitting 600hp. And from all I've seen that's a sure fire way to end up with a split block. But go ahead and keep us posted when you put everything you've got into the gas pedal.iskwezm said:I ran for YEARS with a 175 shot of nitrous on a "stock" block 289 with stock bottom end and NEVER broke anything.I have seen blocks slpit,but only from improperly built combos'.I see absolutly no point in a $2000 Dart block for a street motor unless you just like to brag that it will handle 1000+ HP,but you only have 400????.Everybody can say what they would do,but my guess is you have neither.I have plenty of friends making 475 N/A up to 700 HP on a blown stroker "stock" block.You call it wasted money,i call it what I wanted.So what your saying is put more into the block,and less into the rotating assembly which takes all the stress
Im sure you have your reasons why,and have mine,also working for Ford for many years including R&D i picked up a few things along the way too.
I do have a lot to learn, but the combo that put out 400 was my 289.My 347 is sitting on a stand going in on friday.Ill be sure to let you know when the block splits,but dont hold your breath,it might be whileD.Hearne said:If all you think that combo you've built is 400 hp with a blower and NOS, you've still got a lot to learn.

Oh......... you have a beast of stroker,for being N/A,thats damn fast.My best of 11.30 was my "old" 289 and 150 shot.My new combo hasnt been ran yet and will not see track time due to a mistake in bodywork(shaved door handles)washMO66 said:You do it and I will kick the living crapola out of you, your 8" will be begging for it's 9" daddy.......
So iskwezm, your sig and that ET don't go together? Was that ET with that Mustang or another car you had previous? You were making me feel like my NA stroker was all big and nasty next to your blown / nitroused stroker.
Must have been the sprayed 289?
Max Power said:Actually, now that I think about it, you are correct.
I agree with you on a lot of points.I know my 275's wont handle the power of the engine,they couldnt even handle the 289's power.I know blocks split,I never said they didnt,but when somebody tells you that you just wasted money and it wont last when they dont have a combo close,that would give anybody a little reason to get defensive.I know enough people with similiar combos with no problems.Yes, I do have a blower and NOS,but im not stupid,I will probably never need the NOS except maybe a 25-50 shot to cool the intake charge.This car will RARELY see the track,its more of a show/magazine car.Yes, I would like to race it,but due a bodyman that doesnt listen,some body mods were done,so I can no longer pass tech.The whole car has been gone through several times, and this isnt my first time building a car,so I know the weaks links and they have been taken out of the equation.I take it with a grain of salt,everybody has their experiences,or what they hear of,for me and what i've seen,"we" have never split a block,yet.thats is allmdjay said:isk
Hearne was just saying to use caution. He's speaking from experience and fact. IMO You're being overly defensive. No one is saying you can't make that much power.
The next question is why go for boost and nos on a stroked motor? The sound barrier was broken some time ago by a jetYou can get more than enough power from one or the other.
If you insist, you better consider a narrowed rear end, some huge MT's, a full roll cage and a boxed chasis to stop it from twisting like a pretzel. Because the next problem is actually putting that much power to the ground. A 65-66 stang with minor work can only run a 275 tire. You'll just spin through all the gears. Also, set the rev limiter low ie 6k.
Let's be sensible here. It's a known fact. If you're pumping that much boost and nos through a stock 2 bolt main block, with that much stroke, it's very likely you will split that engine in the valley in a high rev.
I am sincere and not sarcastic when I say this. Good luck!

Can't we all just get along?
Can we just agree to disagree?
