Most people want a 350 small block Chevrolet V8 engines because they have a lot of horsepower but depending on crate engine dealer it’s expensive the 305 does need some machine work and performance parts but it’s cheaper though
The oil pressure gauge isn’t controlled by the ECM. It’s wired completely independent of the ECM harness. The oil pressure signal wire that goes to the sending unit is the tan wire that is on the factory 3-wire CFI pigtail that connected to the factory sending unit. Check for continuity at that wire. If the wire is not open, it’s a problem with the PCB or the gauge itself. You should be able to ground the tan sending unit wire and the gauge will go to “0”.

Awesome video and really descriptive. I’m trying to stroke my 305 in a 87 Firebird and this is really helpful
334 makes a hell of a work truck engine I've built a few of them very cheap to build since nobody wants a 305
