you would need to change the cam too.. it doesn't have the proper hole for the new style distributer. http://i164.photobucket.com/albums/u3/jdhawk93/sidebyside2.jpg


Ahhh... crap...

I just took a look at the newer vented distributor and you are correct - it will not fit into the older style cam.

I could probably have the shaft turned down to fit the older cam but now we're getting a little crazy.

Well, I guess it's a good excuse to buy the LT4 hot cam, and roller rocker kit and change the timing chain too?

I actually have a complete delteq unit I bought a while ago. It has about 2,000 miles on it. I'm a little torn between which way to go - I like the idea of keeping the car visually stock. And if the water pump ever fails and unloads on the opti it will probably kill the optical sensor anyway? Then I'm right back to changing the opti again, so...

I've been torn on which route to take.

Thanks for the advice so far.
