You can cut the base from the air filter housing and then use it on another lower profile air cleaner housing (like taking the truck TBI base and using it on the bottom of the 4cyl fiero housing). Here is the one I used to make the custom air intake housing on my last 4.9 swap:
Also, many speed shops sell TBI spacer rings in various thicknesses so you do not have to use the stock tall one from the truck (I have a 1/2" on on the shelf at home).[This message has been edited by fieroguru (edited 09-14-2009).]

Do you have a picture of the 4.9 with the 2.5 breather on top?

I didn't know that. But I will think real hard before I drill out the bypass. I will either add the oil cooler, or drill out the bypass as suggested.
Thanks for the tip to you both.

Why wouldn't you want to use an oil cooler? These caddy's all came with them from the factory. I'm not one for removing parts that the factory felt was necissary, even if it "can" work without it. This is the one I used. They are quite in-expensive as oil coolers go....

The biggest problem I had was where to put it, so it wasn't next to an exhaust pipe, or a catalitic converter. Both could heat the oil rather than cool it. If I am gonna have an oil cooler, it will have to be one working correctly. I also want to run my AC lines in the factory position. Oil cooler has gotta be in a good spot. I didn't want to move it up front, or in the right side quarter panel.

OH. Right. I forget that can be a problem with some installs. My car is setup differently then most. My intake comes directly through the decklid. That left the side scoop open for the oil cooler. It works extremely well there. At hwy speeds temp stays steady at 200 degrees. The radiator fan only comes on during stop and go traffic and even then only for 10-15 seconds.
How about the front of the cradle? Since your not running the factory cat it could get plenty of air there.

This (cradle front side) was my thought after the tip about the internal oil bypass.
I have about 98% of the Cadillac injector harness finished as of this afternoon. Every wire that goes out to the engine is fitted and tied off for first fireoff. Tomorrow I will start adding the C203/C500. I hooked a battery charger to my fuseable links this afternoon. I had hand cranked up the headlights, and they both came on. The Blue Dingy thingie started singing to me. I couldn't see any dashlights on in the dash pod. Both dome lights were dead. I'll do more power ups after I have the next stage wired in.
This is how much excess wiring was in the Cadillac 4.9 injector harness:

Nope, that was just a sugestion on something that could be tried. I am not sure it would clear the front valve cover, but it would be kinda funny to keep the tech 4 air filter housing.

Is your dash bolted down? There are two 10mm bolts that go through the metal plate behind the speedo/tach. If their not tightened down it wont light. Came accross this on mine.
