Re: which is better???
Hows your fabrication skills? With a turbo there will be alot of that, but more efficient power that is if the block is built to handle it.
With a blower its very easy, remove the old intake and install the blower and carb on top, bolt the belt pulley to the crank and essentially thats it.
With a supercharger, its easier to install than a turbo, but takes up some room and you have to route the intake plumbing, its basically a belt driven turbo.
After that you have to worry about how much psi you can run, how much timing, and the octane of fuel youll be using along with your initial compression ratio. On completely stock engines most can handle 4 to 5 psi safely
In conclusion, i cant tell you which is better in your situation/combo, theres too many variables

Re: which is better???
Are your 350s heads original? If it is one advantage for forced induction of
mid 70s to 80s Small Block Chevys are low compression either induction would work great.
Did you read the article by SuperChevy on how they took the 8.5 to 1 compression crate
350 and topped it with a Supercharger bone stock and made over 350hp and a ton of
torque with the so-so 76cc heads. I like Roots Blowers myself but that's just the look.

Yes heads are stock. I'm used to the power and would like to add more hp.

Define better. Better for hp, torque, drive-ability, ease of installation/fabrication?

Blowers are easier to install. Provide instant low end torque. Wear out faster. Use horse power to operate. More stressful on internal engine components due to boost being constant.
Turbos are more involved to install. Larger ones need to spool up before they make good horse power. More efficient, they operate using exhaust gasses. Less stressful on engine internals because of low/no boost at low rpms.

Re: which is better???
Nitrous is a viable option if you want power for racing. With a good ignition unit for retarding timing it's totally
safe and less stressful than forced induction as it's a as needed power boost. They say most stock engines can handle
150-200hp shot no problem especially with newer products from NoS , Zex , Etc. . Engine Masters made 600hp with Nitrous
and a stock 305 and were only stopped from going further because they didn't file the ring gap to allow expansion.

I saw that and immediate thought of a 305 w vortec and nitrous that's be the 5.0 new arch rival damn stick it in a El camino or something and have some fun
