To stud or not to stud main caps
 

I was reading how to build high-performance chevy ls1/ls6. The main caps are only good for up to 550hp. So i'm trying to firgure out if i should stud the bottom end of my 2000 c5 ls1 block. So let me know what you guys think.

I don't think that 550 hp number is correct, but if I was building the engine from scratch, and looking to maximize performance AND longevity, I would stud the bottom end, and also the heads. Overkill can be a good thing(if you can afford it). lol

yea i know what saying but $200 for a stud kit and $200 to have main caps lined honed.
That extra $400 that wasn't planed for.

What power levels/build type are you planning?

Power level upper 600hp

Getting to the limits of that aluminum block then. You planning turbo or nitrous? I'd stud it.

Running the same set-up that on my 5.3 whitch in my sig.

stud it! I got my stud kit for $169 I think, scpc had them on sale and I called jegs to price match. saved tax and had a flat rate shipping.

But your 5.3 is an iron block.

He was answering your question about turbo or nitrous.
He plans on using the same cam/turbo. he runs 8-10lbs right now and wants to do more with the ls1.
