yes
Yes it will.
A 305 exhaust manifold will physically fit onto a 350 engine, as both are part of the small-block Chevy family and share similar mounting points. However, the performance may not be optimal, as the 305 manifold is designed for a smaller engine and may restrict exhaust flow compared to a manifold designed for a 350. It’s advisable to use a manifold specifically designed for the 350 to maximize performance. Additionally, check for any clearance issues with other components in your setup.
yes
Yes, but the exhaust Y pipe from the 305 may not fit the 350.

The connector into the intake manifold of a GM 305 and 350 has been known to be quite fragile. If the connector has broken you have little choice but to replace the manifold.
A 5.76 car exhaust manifold will fit a 1997 350 Vortec. Your local auto parts store or car dealership will be able to give you a detailed list of all car exhaust manifolds that will fit.
A 283 exhaust manifold can physically fit on a 350 engine, but compatibility issues may arise due to differences in bolt patterns and exhaust port shapes. Additionally, the performance characteristics may not be optimal, as the 283 manifold is designed for a smaller engine. It is generally recommended to use exhaust components specifically designed for the 350 engine to ensure proper fit and performance.
$300-$350 depending on the shop.
yes, direct bolt-in. Might be necessary to transfer peripherals from the original engine such as intake manifold, exhaust manifolds, ignition system, front pulleys, oil pan.
The only one I can think of is the exhaust Y-pipe may not fit from the 305 to the 350.
Exhaust manifold torque is 25 lb/ft with anti-seize lube.
