I want to convert my quadrajet to electric choke because i run vortec heads and there is no provision on the manifold for the heat spring type that i have. does anyone make a kit to convert them, its a 1973 model.

Check out my 73 K5 <a target="_blank" href=http:// members.theglobe.com/xnoahx/73k5.htm > members.theglobe.com/xnoahx/73k5.htm </a>
 
I have herd that the newer Q-jets are better for offroading than the early ones that you and I have. For that reason I was thinking of just getting a newer carb from a J/Y rebuilding it and swapping it in. My choke is just wired open at the moment (which I can only do because of that wonderfull SoCal weather).

no kit available that I'm aware of for the divorced choke your truck should have.
The newer heat riser deal with the pip and the choke bowl housing (around 77 or newer) is a easy bolt on deal. Converted my 79 to electric. You will need an oil pressure switch off a newer GM with electric choke and the electric choke element. You need to put some heat shrink on the fork that the bi metal spring engages but that's it.

It's not my damn planet monkey boy!

I have heard reports that NAPA and J.C. Whitney both sell kits to convert divorced choke Q-Jets to electric - I have never seen either in person. The best route is to do what I did - get a hot air style ('75 or later) Q-Jet, and use the factory parts to convert it to electric choke.

Tried to put electric choke from an '82 K5 on a '74 Q-jet. Won't work. After much wasted time trying to get it bolted up (different diameter bushings for stuff, etc) ended up just putting the whole '82 K5 Q-jet on the 454 instead of the older carb.

No anti-theft measures on your truck? No pity when its stolen
