Guys and Gals,
I need a little advise/help. I have a 2009 GMC Sierra with the 5.3L, I would like to either stroke this engine or upgrade to a 6.0L stroked engine. I have built many engines in the past from NA to blown, so I can build the engine, I just don’t have any experience with the LS engines. I have done a couple of searches but have not found answers to all of my questions, so I am going to list them…I will try not to be long winded.
My goal with this is to up the HP and to be able to tow my 20’ bass boat without spinning 5K all the time on an incline.
1. Will my existing tranny bolt up to the 6.0, if that is the option I go with
2. I assume the 6.0 stroker is the better choice for overall performance and towing
3. Any suggestions as to what stroker kit (6.0 or 5.3), cam, heads, ect to use.
4. Fuel system upgrade?
5. Do away with the variable cylinder deal under light load?
6. I assume all of my front dress will bolt on a 6.0, what about the electronics?
If I have posted this in the wrong board, I apologize or if there is a better place to post please let me know and I will post this there.
Thanks in advance for your help
