If you were around 500 rwhp, and you drove the LS1 'normally' (occasional spirited driving on the street, occasional drag racing, mostly normal driving on the street) does it hold up for 100K + miles or are you compromising the longevity of it being significantly above stock rwhp? Might be a dumb question, but I'm new to this car and trying to figure out where I want to take the car as far as performance.
i just got through rebuilding my ls1 and i was going to keep it stock since i wanted to get my car up and running but im going to order a cam from yall guys on Friday when i get paid i decided to go with a torquer v2 and had my heads ported from my dad good friend dennis weld here in dallas and wanted to see how much could the bottem end hold up dont want to trow a rod imma newbie to the ls1 word

The harder you push the envelope, the less reliable it becomes. With proper maintenance and within reasonable parameters the LS motors are strong and easy to maintain for thousands of carefree miles.
I did a tsp heads/cam setup on a 2000 ss with 68K miles earlier this year, awesome setup and the car pulled hard. I put 1000 miles on the setup and spun a rod bearing. I do not drive the car hard at all, went to the track once. Its my baby and gets treated like it. I made 430 to the wheels and bam, just my luck I guess...so just be ready for anything to happen because its possible, I for sure was not planning on this, car has been sitting for 3 months now. ready for a 6.0.
I know what u mean sorry to hear that I baby my t/a and one morning went to crank it and boom went the rod out the block I nvr really race just want a nice sounding canned ls1 not really trying to drag it to much

Well hod roding did an article where they used twins to push a bone stock junkyard 4.8 bottom end over 60 pulls over 1000hp it peaked at 1204hp at 27psi and still didn't give up, so if ur inquiry is about power adding you should be good for 27psi on boost or roughly 900hp shot of spray

I have had about 550rwhp and running low to mid 10's on spray for about 8 years now. My car just turned 71000 miles and still running good. Granted I am not spraying it every day or taking it to the track every week but it is my DD and at a little over 400whp on motor I do get on it at least a few times a week.
My car turned over 185k miles at the track friday night all while seeing 9lbs from the VORTECH kit that has been on it for 15k of those miles. It was dyno tuned to 450/438 earlier this year. Its my dd and I drive it 500 miles a week occasionally getting on it on the freeway. the fact that I have opted to keep the shift points at 6000 RPM might be part of the reason for it lasting this long but IDK...
