Magnum serpentine belt on a LA?

Not certain, but it sticks in my head that there is enough room to run the eccentric on a Magnum TC cover even though you can't run the fuel pump....But take it with a grain of salt as it seems like something I read and certainly wasn't something I tried.

I happen to have both an LA motor with a cam/timing chain/eccentric and a Magnum TC cover so I took some measurements and bolted things up loosely.

The end of the eccentric measured about 1.875" from the block. The Magnum TC cover measured about 2.0625" from the flat on the inside. And when I set the Magnum TC on the LA block, there was no interference. I should have measured the LA TC cover just to compare but didn't think about it until just now.

So, pretty confident you can run a long snout LA cam under a Magnum cover.

Hope that helps.
