@doctordesoto

I think they should be the same since its the same Block, but im not absolutely sure.
Do they have datecodes closely before January 21/ 1968?

@ Experts: i it right?

Thanks a lot
Joe

Only the Thermactor smog tubes for the cylinder heads are the same on the 1967 system. Make sure that the driver side has the extended
tube that partially crosses over the top of the engine, and with the bracket with a little jog for the coil.

1966-67 used a different smog pump and pulley. 1966-67 smog pumps had 4 bolts holding the pulley, 1968-71 smog pumps only take 3 bolts for the pulley.
The hardest part of that 427 smog system to find will be the correct drive pulley. The rest is 1968 S code 390, or 1968-70 428CJ.

except for the PI intake specific PCV hard tube it is different than the 390 and 428 CJ. Sorry did not get to the pics today but did receive your email. The pumps are dated but typically they are pretty far pre dated to the car so anything starting with 1968 model year production. August 67 forward is acceptable and should be 3 bolt as Scott mentioned. The other dated parts are hoses and the anti backfire canister.
Here is a pic over view of the emission system

Here is a pic of your PCV system which is the same as a 68 GT 500 (pre KR)
