I didn't check far, but found, and IIRC, the FT was produced until '78.

5 bolts is an FE/FT. The "385" series 429 would have 7 bolts.

Your intake manifold should extend under the valve covers.

While the bore and stroke is identical, the FT motors are refered to in slightly different CID numbers.

359/361, and 389/391. The smaller numbered engines were smog motors or U-haul specials, or some other variation.

The 330 used the same stroke as the 352/360/359/361, but has a smaller bore.

Externally the only way to check is via a wire or small dowel down a plug hole. 3.5" = 330 or 361, 3.78 = 391.

The tag you posted looks like a carb tag. A reman tag will say the rebuilder name, and have numbers indicating the oversize of the piston, and undersize of the mains and rods. " .030 .010 .010" or similar.

Your engine should have an iron front cover that incorporates the front engine mount, and the rear engine mounts should be incorporated into the bell.
