it is off a 88-90 astro van with the 4.3l motor. will that work to convert my car.

 

It should bolt up. If it fits right, that's a different story. Truck accesories might cause hood problems. Try to find a pic online to show us.

 

k I'll do that tommorow. I can get everything for free so that is why I'm asking. I'm hoping I can get it to work.

 

here are 3 pictures of the setup.

Throttle body clearance is the usual problem, thats why I am having to get new brackets for my TPI swap into my truck.
although they may have used different brackets on the vans than whats in the fullsize trucks.

 

well since I have it already and got it for free I might just try to mount it up. the reason I want to switch though is because I want a supercharger. and I didn't know if that would work for that.

 

Well hell you can't beat free.
Where is the upper part of the tensioner pulley in relation to where your throttle body would be.
If I were to try and use my brackets with TPI I could not connect the duct work to the T.B. because of that piece.
I hope you can use it because it always feels better when something free works for you.

 

oh hell yes. and I can modify, like I said before I just want the ATI kit to work.

 

how much would a new serpentine belt cost ?

 

The serpentine setup new from GM is $600, and that's just the brackets, nothing else

 

Hell I only paid $250 for mine brand new.
