That's why you would need to change the timing cover and water pump to the Magnum style. Also the power steering pump bracket needs to be one from a van. The one from a truck will hit the battery. Most newer engines use the reverse rotation water pump. This can be identified by the smooth water pump pulley.

You may need lots of washers to shim the Magnum brackets on the LA heads, which may or may not be stable. Scott B. "I'm a self-made man...

I have a Professional Products Crosswind intake (Airgap clone). Ditto on what Dakota Dan said, you will need the correct timing cover. I have magnum heads so I didn't have any issues there. Motor is still on the stand so I can't tell you how well it does/doesn't work in reality. Mines headed for a truck so I'm not too worried about clearance issues with P/S pump.

Where are you putting the brace for the alt on the Crosswinds intake as well as the other brace that holds the A/C Without these braces the big aluminum bracket will crack. 7594189-SAM_3662.JPG (40 downloads)

I am not real happy with how much I had to cut the bracket and am thinking about how to add some bracing. I haven't even set the accessories in place yet. I am still toying with the idea of going FI and using the beer keg which would make things a lot easier. Megasquirt or similar is a lot of $ though.

Mines headed for a truck so I'm not too worried about clearance issues with P/S pump. The edelbrock intake will mount the magnum style thermostat and waterneck eliminating the problem with grinding on the ac compressor (Found this out after the fact). The reverse rotation waterpump doesn't affect the operation of the cooling system by any means. I also didn't have any problems with the power steering pump being too powerful for the steering box. Had it in there since july 2012 and have had no problems with blowing seals or leaking. As far as I know the steering box has never been touched.

Anyway, you can lay a straight edge across the end of the magnum heads and all the attachment points will be on that same level. Laying the straight edge across the end of an LA head, you'll see that different bosses are machined at different levels. Scott B. "I'm a self-made man...
