i got a 1983 camaro z28 and i blew apart the old 305 it had, so i got my hands on a short block 1989 rollor 350 the was bored and forged, so now its a 355. i added fastburn heads shorty headers and some other things but my main problem is when i went to put up my powersteering pump it dont match up to any of the holes. what happened here? and also what trans was in the 83? 2004r or the 700r4? now i have no computer and the trans is shifting different now did i miss something?

I've heard of some GM performance heads missing an accessory bolt hole, but not sure if that's your problem. Do any of the holes line up?

The rear PS bracket bolts to the front exhaust manifold mount bolts. The manifold is thicker than the header flange, so you need a spacer between the flange and bracket, and need to cut off the rear bolt hole and only use the front bolt. Were these new or used headers? Did they come with instructions and fasteners? Most of them take care of this issue.

Did you use the same induction system you had on the 305? If you changed to a Holley, for example, and have the TH700R-4 transmission, you need a geometry corrector bracket to bolt onto the throttle arm to get the throttle valve cable to work properly.

In '83 both the TH200C (not TH200-4R) and TH700R-4 were offered. If you shifter has "P-R-N-3-2-1", you have the TH200C. If "P-R-N-OD-3-2-1", you have the TH700R-4 and you'd better get that TV cable right or you're going to mess up your transmission.

the headers are used but thats not where the issue is the front doesn't bolt up anywhere at all, im so confused, i also cant fins some of the brackets at this point but i was looking at summit and found this part#MCH-20165 i think that might help me cause it is only one bracket not a binch and itlooks a lot better to. and as for the trans its a 700 but i am using a edelbrok carb not i got the throtle hooked up fine and the kickdown but whats the tc cable? im not goos at auto trans im more knowledgeable with standards. but aslo my bracket i have was modified to work with headers just like you said there was headers on the car when i bought it, btw now my valve covers are the centerbolt instead of outter bolts,

If you've got a TH700R-4 transmission, that isn't a "kickdown" cable, but a "throttle valve" cable. It tells the transmission where the throttle is, and the transmission uses that to vary pressure, among other things.

If you have an Edelbrock carb, it isn't possible to properly hook up the TV cable without a "geometry corrector bracket" that bolts to the carburetor throttle arm. If you drive your car without it, you will damage your transmission. You said it shifts differently than it did before - guess what, that's why. Get that bracket and hook the TV cable up properly before you do more damage.

i dont know if its just the way i read it but it seem like your being a little rude, sorry i dont know auto trans and thought it was a kick down. and i dont know why its "imposable" to hook it up right iv seen my buddys car with the same trans same carb same brackets as me and it works 100% fine, my trans is kinda on its way out and im swapping out to either a 5 or richmond 6 speed shortly. so im not goin to wast money on a new bracket my main concern is my powersteering.

No intent to be rude, just informative.

The common TH350 had a "kickdown cable". It wasn't vital to the function of the transmission. All you had to do with them was make sure it pulled all the way out when at WOT.

But, the TH700R-4 is a different animal. Calling it a "kickdown cable" gives the impression that you can treat it the same as the TH350 cable. The point being that you cannot - if improperly installed or adjusted, you'll burn up a TH700R-4. Without a geometry corrector bracket, it may seem to be operating okay, but it's a ticking time bomb.

But, sounds like you aren't keeping the auto trans, so the above information is available for anyone who may happen to come across this thread via search.

As for the power steering bracket, most likely your brackets will work. Certainly for a lot less money than the set-up you linked. I know it's confusing if you didn't take pictures of it when taking it apart (juggled it around myself more than once). There are pictures of the brackets installed that have been posted.
