What size bolts are used to attach the belLhousing engine block on a 1965 Chevelle?
A 1965 Chevelle's bellhousing to engine block bolts are typically 7/16"-14. However, it's crucial to verify this with a shop manual specific to your engine (e.g., a small block Chevy or a big block Chevy will have different specifications, even within the same year). The bolt length will also vary depending on the specific bellhousing and engine combination. Always double-check before purchasing or installing bolts.
