My '72 CJ has the 4 bolt mains. My '74 CJ has the 2 bolt mains. 1973 was the last year for the CJ 4BM blocks, but like others have said, a 2BM block can stand a lot of HP.

'73 still had 4 bolt mains. Smaller valves and a wee bit less cam compared to '72. The intake will have provision for the EGR port. Exhaust manifolds are the same. The rest is the same.
The CJ had a 4-6 degree retard built into the cam gear. This can be easily fixed with a good quality gear & chain replacement.
Auto cars had single points, 4 speed had dual points.

All 2 bolts can be tapped for 4 bolt mains. Blocks are  identical. Some even claim the 2 bolt is better by not weakening the main caps with  the extra 2 holes.
Other than heads exhaust and intake the 73 did not have the 4 degree cam timing delay for emissions yet like  the 2v versions.

HEADS have 4 stamp, Block is likely a 2bolt in 73. All 351C's are the same so the CJ part you are basically buying the heads and intake. If it is complete maybe 500 as a good rebuilder
