Going to install 5.3 out of 03 silverado in a 78 trans-am. would like to upgrade it with a turbo. any body sale a turbo kit or what would be good turbo for pretty much a stock set up?

That thing is stronger than you think... of course you will need new valve springs for backpressure, but you will able to push that motor safely further than a stock-inch LS1 with a turbo. I would look towards a 76mm for that setup. The TC76's seems to be a good deal for what you get.

thanks, gives me an idea which way to go.

With an A2A IC and some supplemental meth injection, you can make almost 700 to the tire with that motor and still keep it together. Amazing...

a little more (30-50 hp actually) the intakes are more free flowing for carb'd applications.

I wouldn't bet on 30-50HP!
