LA 318 with Mag Serpentine

The timing cover will physically fit, but you'll have to swap to an electric fuel pump and a short snout magnum style cam...

The accessory brackets? I'm not so sure they bolt in the same place with the bolt holes in the LA heads--I can't recall

I believe they can be drilled. I plan on using EQ heads. Hopefully they are already drilled.

My main concern was the oil pan sealing surfaces. I know the rear sealing surfaces are different between the LA and Mag 318. I suppose the timing cover end of things is the same.
