Here are some popular choices, but you MUST verify compatibility based on your specific 350's year and the transmission's details:
* Muncie M20, M21, M22: These are iconic transmissions known for their strength and are common choices for 350 Chevy applications. Different versions exist across several years, and finding the correct bellhousing is crucial.
* Borg-Warner T10: Another strong and popular choice, often found in older muscle cars. Again, various versions and years exist, requiring careful consideration of the bellhousing.
* Saginaw 4-speed: Less common than Muncie or T10 but still a possibility. Again, finding the right bellhousing is critical.
* Richmond Gear: Richmond offers new 4-speeds designed to work with small-block Chevys. These would likely have a more straightforward fit.
Crucial Considerations:
* Bellhousing: The bellhousing is the critical part that connects the transmission to the engine. You need a bellhousing that matches both the transmission and your specific 350 Chevy engine. The bolt pattern varies between years and even within years (especially with aftermarket blocks). Getting the wrong bellhousing is a common mistake that prevents the transmission from fitting.
* Input Shaft: The transmission's input shaft must be the correct length and spline count to mate with the engine's crankshaft.
* Year of the 350: Small block Chevy engines have seen design changes over the years, impacting the transmission compatibility. The year of your 350 is essential information.
Recommendation: Don't just rely on a list. Before you buy *any* transmission, consult a parts catalog or a transmission specialist to ensure you get the correct transmission and bellhousing for your specific 350 Chevy engine. They can help identify the proper combination based on your engine's specifics.
