vortec vs ls1 build
What are you putting it in and what are you starting out?
If you are doing to have to do an engine swap that may play into the overall cost.
It's easy to get 400 flywheel hp from a vortec 5.7
The most important part of the equation is the vortec heads. Up the compression some and a small cam and you are there.

I'm am putting it into a porsche 944 (3000lbs). I have set aside the amount I will need for all the conversion parts and such. I know I'll have about $1000 for the engine itself. With the cam, would that be increasing the overall powerband or is it just making a peaky powerband.
It depends on what cam you choose will dictate if the engine has overall power or is peaky.
The same can be said for either engine platform.
IMO if you have a grand to spend on the motor save some more money. Either way you are going to be strapped and will have to cut corners somewhere.

That is incorrect year and model data. There is a Government truck at my office that we have had since last year and it is a 2010 chevy silverado 2WD 5.3L with 799 heads on it. You can find the 799/243 heads on ANY GM truck platform from 2005/6 and newer 5.3L's.
My bosses 2007 or 8 avalanche has 799 heads on its 5.3L too.
