best option f0r 130k ls1 motor what you guys think is the best way to go to get 400-450 horses out of a 130k mile ls1. is it worth to do cam+header combo with x pipes . or the motor is too old to play around with. and is it cheaper to get new ls3 rather than rebuilding ls1 for 450 hp . thanx .

We could rebuild your LS1 into a 383, hand massage your heads a bit and bring you to that hp level for a little more money than a decent head and cam job that your not sure how long the bottom end will last under.
It would be a much more solid combination that you know you can trust to take the abuse. Not saying you cant and wont get good mileage out of a h/c combo on your current LS1 but at that mileage my personal thought is the better money spent with more productive results would be to rebuild the bottom end and add some cubic inches.
We have a formula for a 383 that is great for a budget build. It would be way less money than a new LS3 and would be a great way to go for a solid 450+ hp. It makes more sense than dropping money on a high mleage bottom end.

will it be more economical to strip the old motor and build it with better new components....that will be great if there is any list of better parts that will go in bare ls1 block n where to get them . like pistons , springs,etc.

pm'ed those interested,
We take your current LS1 stroke it to a 383 and work the heads over for you. You get back a precison built HKE 383. As far as the top end it all comes down to budget.
At the very least you've gained a new forged bottom end of more cubic inches which will net more power even if we do nothing to the heads. Timing set, oil pump, lifters and pushrods we take into account your budget and make the best choices for you.

compression and leakdown test first, but rather then opening up a motor with those kind of miles and running a cam that is harder on the valve train and that would make you spin the motor to a higher rpm. I would spray it with a 100 shot and i bet it lasts longer.
that would be the quicker way to a forged bottom end.

If I wasn't a broke college student I would take you on this bet. Nitrous is hard on a motor which is why everyone rebuilds with forged parts. I bet the cammed motor would last longer than sprayed. Like he said.. spraying is a faster way to get that forged bottom end he wanted.
