All Chevy transmissions will bolt up to the 350 small block and big blocks from 1999 down. They are all the same. GM. did not change until late 1999.
Yes , but you will need a tbi intake to fit vortec heads if you retain the 90 TBI fuel system.
They are both the same engines. You refer to a long block as being a compleat engine assy. 350 small block is what it means. It's a 350 and that is called a small block.
yes, a 305 and 350 utilize the same block
Yes their the same block....
To my knowledge the only small block flex plate that doesn't interchange is the small block 400.
