I need advise regarding putting 72 carbs on my 73. I want to delete most pollution devices, should i replace the manifolds too (intake and exhaust) as there are several differences between the two, including the balance pipe with egr. how far to go? can i defeat items without much trouble ?

get rid of all the extra(useless pollution crap) you can. I would recommend using the 72 intake, I'm assuming you'll be using SU's... I dont think theres any difference in the exhaust, except the hole for the EGR pipe, you can just block it off. if you do change the exhaust, make sure the ports are identical (rectangular or round), I just dropped a 2.8 drive train in my 71 and used all the 71 bolt ons, man what a huge difference!!! I am so happy with the result. good luck, drop me a line with any questions or Z stuff. TIM
