440 or 454 Stroker, Which is better?
Thanks for all the replies.
Still deciding the direction Id like to go. Ive had nothing but issues with the magnacharged 403. Right now I have some lifter issues and a possible bent pushrod. Already had to pull the heads to replace headgaskets.The magnacharger is not all I want it to be so its time for a new build.
I still have a low mileage LS2 403 Shortblock and AFR 225 Heads to work with but Im thinking about ditching them for something bigger.

I'm talking about the weak stock factory LS7 sleeves......thats the weak point on the stock LS7 engine. Re-sleeve an LS7 or an LS2 block and they become monster strong. Easily hold more than 1,000 hp.

The LSX iron block can probably take a dual stage 600 shot with no problem all day long......if its built right. I'm just saying, if you bore the LSX iron block to 4.185 you won't have much gasket between the cylinders and you will blow that gasket pretty soon, possibly the first time you spray it with a 200 shot, unless the tune is just PERFECTION. But it still won't last long that way with a 200 shot.

Once again you have no clue what your talking about.Why you feel so incline to reply to people questions is beyond me. Time and time again you give advise on matters you know little to nothing about. Have you ever built a 4.185 bore motor? Funny how every major engine builder out is building big nitrous motor with over your 4.125 bore recomindation.But hey,"they will possibly blow the gaskets the first time it eats a 200 shot", right?! My advise to the opp is call a engine builder and pick his brain. Don't get advise from the internet on stuff like this.Some people that know will reply like Eric from HKE did,but you will also get people that will repeat everything that they here from there doughter,sister,cousins,friend and try to make you feel like it's the end all truth.Any dumb *** with eyes can tell that the further you bore the motor the smaller the gasket gets between cylinders.Where that becomes a problem is for your engine builder to direct you on.When i built the motor for my race car we went with a 4.100 bore. It has a 114mm billet wheel feeding it though(2000hp). Bit different than a big inch street motor on gas. A 454 will take a 200 shot all day long. It's ridiculous to say otherwise.

Its a RECOMMENDATION....not to take a standard LSX iron block to 4.185 bore and then spray it with a big shot. If the tune is not PERFECT every time the gasket will go. Any detonation at all, and bye, bye. Then you have an exspensive block bored to 4.185 and nowhere to go from there except N/A or a little shot. The OP wants a BIG shot. Its smart for people on this forum to let him know that a smaller bore will be SAFER, thats what I told him. Who gives a damn if a few people spray 4.185 bores....its a risky way to play.
I asked Steve at RED about a 454ci I wanted to build last year and he highly recommended I NOT go 4.185 bore with the 250 shot I wanted to spray.
Remove your head from your *** and stop giving stupid advice telling people to push everything to the max.
And BTW, Eric did not comment at all on "nitrous" and a 4.185 build in this thread. Just said a bigger cubed motor revs faster and makes more power.
I'd like to see one builder say that a 4.185 bore is safer than a 4.125 bore for a 250 shot............giving up some cubes when you'll be spraying a 250 shot or bigger to stay safer and more reliable IS THE SMART WAY TO GO..........thats the discussion, stick to it or stay the **** out of the thread.
.
Just because you can care less about people spending money on an expensive street/strip engine and then running it on the ragged edge.....doesn't mean you should tell people to do it as well.

While there is less sealing area between bore at 4.185 than 4.125 you can run both on NOS engines but we do recommend starting smaller on bore sizing with BIG NOS as people burn up so many pistons in general especially when going 300+ and learning how to tune but with good knowledge and experience you can run the larger bores. It is true that the cylinder walls do not get stronger with bigger and bigger bores but the LSx seems pretty strong at 4.185 bore. So as far as I am concerned it depend on where you are in the engine building process and NOS learning curve.
As far as myself I probably wouldn't start out at a really large bore even on my own NOS deal as I know there might very possibly be a few unscheduled rehones in it's future so I wouldn't want to already be near the edge of the block right off the bat. If you are extremely sure of yourself with tuning and your NOS knowledge though you could do it right away but you are potentially taking some life away from your engine if anything bad goes down.

as long as a monkey isn't tuning it?
