just want to know if i can fit a chevy 350 small block and tranny in a 92 shadow body and if not is there a manual transmission to fit 2.5 turbo shadow engine

well, if you had a lot of money, I'm sure you could make a 350 fit (though you'd have a lot of weight in the front of the car and mess up the balance of the vehicle greatly) though making it fit transversely no. Yes, there is a 5-speed manual that will go to the 2.5 liter turbo I motor, though it's rare to find it.
