$$$ in a 305?
Is it worth it to bore a 305 if it needs rebuilt or just go ahead and get a 350 and swap it out? I have heard the 305 is very unpowered compared to the 350. Also I could use the 305's 3.480 crank with 5.7 rods in the 350 right? I know the intake and carb can all be swapped.

Go 350.......you won't regret it. The power difference is phenominal, and the mileage is actually better with a 350 depending on the vehicle. Yes the 305 has parts you can use if they are both the same design, ie 1 piece or two piece rear mains etc.

go 350 for sure. The 305 doesn't even take modifications well because its a full blown bonafide smog engine.

Think about it ... you can drop the same amount into either engine doing the same thing (pistons, crank, rods), since all but the bore is the same. You can pick up a good used 350 for cheap. And most of all ... there is no replacement for displacement. You will never regret having a 350 (or stroked 383
 ). You will always have second thoughts about a 305.

So since the 305 crank is the same as a 350, could you put in a 3.75" stroke crank? What would that do?

Yeah it makes it a stroker and a mean ass lil one too lol, I had done it a few years back, parts were free and all I had to do was notch the block and buy some bearings. The draw back is the displacement and the heads. They do not flow worth ish!
Get a 350 block and get some hypereutectic pistons for @100 send it to the machine shop have it all balanced and throw it together and you have a very reliable fun motor for next to nuffin.

Yeah I'd like to have a nice 383 with a mean sounding cam, but still drivable. The transmission has just been rebuilt with a new TQ convertor, thats why I ask the stock stall speed or at least range if someone knows.....I searched google but came up with nothing.

stock stall ranges between 1900-2100 depending on what year AFAIK.

Its a 84, and the cam I'm looking at operates between 1500-4500 RPM, so I should be good right?
