TBI to TPI

Prolly a stupid question that has been asked a milion times but here it is again. I have a LO3 305 TBI. Is it just the intake that is different than the 305 TPI??? Are all the basic block and cam specs all the same?

Intake, wiring harness, computer (maybe just the chip?), Everything else I am pretty sure is the same. Use the search button or check the Tech articles on the TGO main page for more info.

The only thing that they share are the short block. The heads are better, the cam is bigger, the fuel system provides high PSI. Also the exhaust is bigger. Stock for stock they don't share much at all but displacement and short block.
