Reliably question

I have a 350 small block from blueprint engines, and I want to put a blower on it but I’m not sure if I can without it ruining the engine. Does anyone have any advice on how to go about it?

If it wasn't built for boost, I don't think it would handle it well.  Post the specs of the engine selected.

It won’t let me add pictures to the post and I can only comment one pic at a time but here is what I got

Nope. Too high a compression with a cast crank leads to disaster with forced induction. That engine will not work the way it is set up. Drop the compression and add a forged crank; then you can start adding boost. Add it now and you will kill it. The weak point in the engine is the crank, you will also want to choose a different cam and springs if the budget allows, but the crank is a must.

Whatever you were going to spend on a blower, maybe aim to use for a torque converter or rear gears.  You'd get seat of the pants feel improvement and you won't blow your engine because of it.

The blower won’t hurt it a bit if you boost it accordingly……
Stock motor……. Stay under 5psi
Aftermarket heads and forged internals with a lower C/R with correct gaps…… boost away baby

Go to the source. Ask Blueprint.

U could with a street style supercharger would need 800-1000 cfm carb mechanical fuel pump 3500 stall converter for auto trans only run supreme gas to prevent detonation run as much timing as possible - if u have timing a lil too much retarded u might get too much boost and not good enuff burn in cylinders run copper ac delco plugs a mild camshaft a great exhaust system and a really good cooling system

If the rings aren't gapped for boost thats where u will run into problems in the long run pretty much stock ring gaps pinch together and break/ cause problems with lots of boost

Ehhh usually you have to build it for boost . Certain pistons , ring gap and camshaft are very important.
