Yes, there's a sticky about putting a BBC into a 3rd gen in the top section of this forum.

 

Depends on the engine. They're not all the same. What year is it?

Truck engines are low rpm torque motors. They're usually a good platform for a buildup but don't expect much more performance in stock trim than a good 350 SBC. The first thing that should be replaced is the cam and lifters followed by the intake and probably carb. Depending on the castings, the heads are probably restrictive peanut port heads but there are a few good older castings.

If you follow the sticky, the swap isn't that hard but it's not as easy or cheap as a good SBC.

 

will i be able to use the tranny thats already in the car

 

it will bolt up but ull need to have it built to withstand the torque when u make that motor really put out power.....

 

That is covered in the sticky.
