block is D2AE-Ca = late 71 to early 74 351CJ block
Heads are D3ZE aa =CJ heads 73-76cc 2.19" intake, 1.71" exhaust with 2.50" X1.75" intake ports and 2.00" X 1.74" exhaust ports
Balancer is D1ZE-=351C
Rods are DOAE-Ea=351 2v ORr351 4v Rods

Not a bad pile of parts, just not crazy about resleeving the block...More of a personal preference.

Also might want to think about getting a built C6 transmission, as the C4 unless it's specificly built for it will not handle the potential torque of the 351CJ build.....
