I'll try taking a stab at this. I'm thinking it won't fit under the stock hood. But under a cowl hood, yes.

The 144 is 8 5/16" from the block deck to the top of the case. A holley carb is 3 1/4" from the base to the surface the air cleaner sits on. Say you run a 3" filter. Now your looking at 14 9/16". A drop base filter housing would bring it down some though.

The height of my 671, manifold plus case, is 11 3/16". The raised mounting surface, 1" injector plate, 2" spacer, and gaskets comes out to another 3 1/2". So the whole thing from the block deck to the top of the spacer is 14 11/16". Since my hood is cut it makes things easy to see. The top of the spacer is flush with the top of the hood.

CoggedBelt75,

I notice you drive your truck daily.  How's that drive with a supercharger.  I drive my 82 Blazer every other day and have considered the 142 supercharger, but I was just wondering how the drivability was.  I'm hoping my gas mileage will encrease if I install the 142, I'm getting 14 to 16 mpg right now.  It's a 302, so it's a real turd.

I have no issues with the drivability department. No different than driving one with a regular intake except for the bottom-end torque that is produced. LOL...don't expect better milage unless you can exercise foot control, which after 5 years I still can't seem to master.
