Will a C4 bolt take a 460?

Will a C4 bolt take a 460?

Ford never put the C4 behind a 460. The manufacturer of the bell housing can tell you what flex plate and converter size you need to run to be compatible with their housing.

What kind of bolt pattern does a 351 / 400m have?

This makes a 351/400M block easy to identify. However, the 351/400M block has a Ford big-block bellhousing bolt pattern, which means a big-block C6 or Top Loader for your M-Series engine build. This is the same bolt pattern used for the 385-series 429/460-ci big-blocks.

Is the 351C the same as the 429 / 460?

351M/400 has the same pattern as the 429/460 too. IIRC the 351C has the small block pattern, as does the 240/300 six bangers. 351M/400 has the same pattern as the 429/460 too. Click to expand… The early 260/289 5-bolt pattern is not the same as the six cylinder.

Is the Ford 351C small block or small block?

What’s the casting code on a 351M crank?

A 351M crank will have a 1K casting code. 400 with 302 bellhousing was made in ’73, and will also have the regular 400 bellhousing mount casting. Top 2 bellhousing bolt holes are 5 inches apart on a 302, 7 3/4 inches on 400. (see image at right)
