L94 & 6L80 Into My '92 2dr K1500 Blazer

Here's the new motor mounts. The base of the mounts is convex and flattens out when torqued down. New to me, but apparently as designed.0007 New Motor Mounts (Custom).JPG

Got the L94 in and test fitted today! It's back out now, but I learned a lot doing this. First, my oil pan is fine as is. It's one inch higher than the suspension nearby and the front crossmember. It's three inches higher than the front Diff skid plate. One of these days I'll add a skid plate that covers both the Diff and the oil pan. Also, tons of clearance everywhere, except for one spot I'll talk about in my next post. More than enough room to install the exhaust manifolds after engine installation. Also, no need to remove most of the accessories to drop the engine in. The power steering pump is the exception. Pretty hard to get the motor mount through bolt in place with the PS pump in place.P1030599 (Custom).JPGP1030598 (Custom).JPGP1030601 (Custom).JPGP1030597 (Custom).JPGP1030596 (Custom).JPG

Close Boss 2 (Custom).JPGClose Boss 3 (Custom).JPGClose Boss 1 (Custom).JPGThere is a boss that is damn close to the motor mount, maybe 1/8" at best. Also, a tab on the oil pan is awfuly close, the tab right by the offending boss. I'm thinking of grinding about 1/4" of the boss and tab off. Is there any reason I shouldn't? There's no way it could ever be used considering where it is...

Got the fan mounts done. I'll post pics of the fan shroud later, I had to chop it up a bit to make it fit. Most of that won't show though, should look pretty factory. BTW, the connectors for the motors are GM # 13580874 or ACDelco PT2649. $15 at Amazon.

Here's the Fan pics. This would be a great mod even for a Stock 350. I picked up a low mileage fan setup complete for $120 on eBay.

I trimmed the bottom down about 1/2" so that it was even with the ridge. Trim the top by the same amount the bottom was trimmed. I also had to remove the driver's side bottom mount; it interfered with the frame. You can see I trimmed the middle mount too. I had to notch the top on both sides to clear the top radiator supports. I cut off extensions on both the left and right side which left a hole, as you can see on the passenger side. I'll patch that later. Then I braced the bottom radiator support with 1/8" x 3" aluminum plate. Below that I mounted a 1/8" x 1.25" steel plate angle iron. That was mounted as to leave 3/8" clearance from the bottom radiator support. I stopped short of my winch control box on the passenger side. The extra wide portion of the bottom support circled in red matches up perfectly with the passenger side bottom mount on the fan shroud.

Later, I'll use a piece of sheet metal to complete the top mount. I'll clean up the cuts with some sandpaper; should look pretty factory when it's done, at least from the top. LOL

This works great! There'es a bit of space on the left and right side between the shroud and the radiator--about 3/8"--which I'll fill with heat resistant foam tape. Easy to put bolt up, easy to remove. Just slide the fan shroud down into the gap between the angle iron and the bottom radiator support, install bolts at top. Factory parts and lots of airflow.
