ok so it's 350 TBI with edelbrock 6085 heads, intake3704, cam 3702.. first question is I was sure I took all the sensors off the block before I brought it to the guy.. I picked it up and he gave me a knock sensor and said I should put a new one because it was pretty coroded. problem is I have my knock sensor here at home.. is there two of them on the block? or did he just think it was mine.. the other problem is he put on the nice edelbrock elite valve covers but the hole for the pcv is now at the back instead of the front of the engine.. can I replum the hose to the back?

 

There should only be one knock sensor, right in front of the starter in the block. As far as redoing the hose for the PCV, no problem. Just get the right size hose at any auto parts store however long you need it and hook it up.

 

You should get a universal hose and cut it to length yourself.

 

Congrads on your swap. I just did a simlar swap on my 88 Firebird. You only have one sensor but you already knew that since I have reponded sooo late.

 

yeah that was my stupidity.. the knock sensor and the coolant temp sensor almost look the same! I haven't actually sat down to start reinstalling the sensors yet.. I guess I would have figured it out then! the knock sensor does look pretty corroded so I think I will replace it.

 

how often should the knock sensor be replaced? what does it control? i know mine hasnt been replaced in my 88 and it has over 101k miles on it...
