I hope I'm not about to ask questions that have been answered a million times. I've been searching for a while but never quite find the info I want.

I have a stock 00 silverado with a 5.3L.



I want more torque. I originally wanted a Magnacharger and may still get one, but for the price I could do a 6.0 swap and buy heads and a cam. Well I found and bought a cheap 6.0 long block. What I would like to see are dyno sheets for stock 5.3 and 6.0 just to get an idea of how the torque curves compare. I know that there are a lot of factors like different dynos, etc. I don't know if someone might happen to have baselined a stock 5.3, swapped to a stock 6.0 and re-baselined it? That would be perfect. Or if anyone knows of websites where they baselined those. I've tried looking at different super charger websites and stuff like that but none have shown me a baseline for both 5.3 and 6.0. I've read a few good mag articles about mods to 6.0s with good dyno comparisons but I want to compare those 6.0 numbers to my stock 5.3.

One mag showed a good 40lb increase on a 6.0 from LT headers and a tune. So if the stock 6.0 makes another 40lbs or so, and those simple mods would make another 40, then that would be pretty significant for very little money. My long block was $600, headers are about $500, and I'll be getting HP Tuner's software for my 67 Firebird LS1 swap anyway.

The other thing I'd like to know is how much from my 5.3 will work on the 6.0? Are the intakes the same? I imagine all the sensors are the same. Can I put all the stock stuff off the 5.3 on to the 6.0 long block or would that be less than ideal? For example maybe the 5.3 intake flows less than the 6.0?

Sorry for the long post. Thanks for any help any one can give.
