The orginal LT1 intake swap had an oil leak at the rear distributor. This was caused by the distributor being at an angle. Don't ask me why GM did this, I didn't even notice it till after I did the swap.
Well, I thought about it and modified the spacer to fix the problem. Here's some pics:

Before



After

 

nm the pictures work now


Question.. did it change the timing?
may want to check

 

Change the timing? All I did was make a angled spacer. The block sets the distributor angle not the intake. Hell the distributor doesn't even touch the hole except for the pad. The intake hole is just a feedthrough.

 

musta been the pictures being different angles or something.... looked like the distributor was a bit cockeyed and sits up a bit higher on the second one.

if the spacer changed how hight the distributor sits, it will sit in a different spot on the gear.. subtle change but if you didn't retime it after you did.. it might have moved the timing a shade.. that's all the point i was roundaboutly trying to make

 

John Millican,

You get my email to you last week? Never got a reply, am interested in your LT1 intake conversion..........

Thanks,

I replyed to all e-mails every day. If you didn't get a reply I didn't receive your e-mail.

 

I understand what your saying about the timing gear. Oh and BTW, all GM distributors are at an angle.

The only real point of the pictures was to show the angled distributer shim that's required to set the distributor at the right height.

 

Looks great John. Now just quit using JB Weld.

Truly, it looks great! :hail:

 

I still like the cold weld, I don't like the idea uf using lots of heat on the mate surface. I would much rather have cracked JB Weld then a vacuum leak that can't be fixed.

 

John, the pictures look great. The additional light and zoomed in shot not only show a clearer
picture but also show the cut away required in
the EGR valve area for distributor clearance.
I agree with you, JB Weld it" Cast aluminum, like cast iron, requires very special hot welding
procedures and techniques that most certified welders don't even attempt. It must be heated to a specific temperature, weld a little, pean a little, grind a little, heat some more, weld a little, pean a little, and so on. COLD WELD, no
problem.
