Will a Chevy 350 bolt up to ford 4 speed transmission that fits 300 in-line 6?

No, a Chevy 350 small-block V8 will not bolt up to a Ford 4-speed transmission designed for a Ford inline-6 (like the Toploader). The bolt patterns on the transmission bellhousing and the engine's crankshaft are completely different between GM (Chevrolet) and Ford. You'd need an adapter plate, and even then, it's a complex and potentially unreliable conversion requiring significant modification and custom work. It's not a simple bolt-on swap.
