Iron head vs FWD Bracketry/Pulleys compatability?

[Fastmax32168]

Will the bracketry/pulleys from a Camaro 3400 bolt up to the front of a 3500 if the timing cover from the 3400 is switched over?
How about the 3.1 bracketry/pulley setup?
If not exact is it close enough to be adapted fairly easily?
I need to figure what I want to pull off of a car at the U-pull it for my 3500 Monza swap.
Thanks

I think the holes in the heads are the only ones that differ but as far as I remember you can enlarge the holes in the brackets to match up.

It sounds silly but it's important to remember, "3100, 3400 and 3500" are titles given to only the generation 3 engines. The Camaro 3.4 is a Generation 1 60v6. The previous 2 generations are simply known by their displacement in liters (2.8, 3.1 and 3.4). This will help to avoid any confusion when asking for very specific information like this.


Now, to help...

The alternator/compressor bracket from a 3.4 Camaro/Firebird will work just fine on a 3500, however you will need to drill out 1 hole that's already cast into the bracket. The bottom bolt lines up perfect with the hole in the front of the block, however if you are using an external crank trigger like i am then you'll have to get creative there. I ended up cutting one leg off of my trigger and a hole through the alt bracket, then using several washers i got the spacing i needed. I also had to make 2 other smaller brackets, one to raise the alternator about 1/2" on the right side to clear the valve cover and one to offset the belt tensioner since the a/c compressor isn't being used.


The PS pump bracket from that car also works, I had to drill one mounting hole to bolt it to the head and the lower side bolts to the water pump like normal. I remember having to notch it in one spot but that might be from the 2.8 timing cover i used (which is being replaced with a 3.4 cover).

you'll have to use the 3.4 timing cover and water pump, and you will have to enlarge 3 holes in the timing cover (and i think one or 2 in the water pump where it bolts through to the block. Use a drill press.. trust me. Also there is a tab at the top that you'll have to cut off and a hole to plug in the timing cover on the right side, if you don't you'll dump coolant everywhere.. lol


I can post up pictures tomorrow of everything in it's place, my swap is very close to hitting the road..
