Get something a little higher on the exhaust dur/lift. That will help the vortecs seeing as how thats their stock week point.
Seal against the front of the block. It's been a long time since i've had a vortec engine in front of me but IIRC the front block surface has a different shape and thus the cover may not seal on the front of the older style (non vortec) block.
I got the motor pulled out of the sub today and I will tear it down tomorrow. I really think its going to work. That vortec cover looks like it is going to work perfectly. But I will let you guys know when I do. Stomis, I plan on useing the vortec cam. Do you mean something different?

Gives all the info on the swap. These guys are doing the swap in order to run OBDII on the older TPI engines. There are several up and running, so yes it can be done with no problem.

The cover bolted up perfect. I had to remove the dowell pins from the older block to make it work because the vortec cover has pins molded in to cover. I should have it in next week. I will let you guys know how it goes.
Oh shiz page 5, Alright guys i got the motor in the sub and it runs like a raped ape. The ONLY problem I ran into was the cam thrust plate. On the old block there was no thrust plate, on the vortec it uses a thrust plate. I took two thrust plates and cut the ears off of both and welded them to make a wider bolt pattern. This can be done. So specs are a 92 350 block and vortec cam, homebrew thrust plate, vortec cam, vortec heads, lifters. pushrods, vortec timing chain, and waa-laa! Thaks for your advice.
Or you could have bought the correct thrust plate (GM # 10088128) from gmpartsdirect.com for $8.20. You sure better hope that the plate you welded doesn't break.
