MAG MPI intake manifold options?
2001 454 MAG MPI, lower manifold corroded. Options I've come up with so far:
replace with carb (requires a bunch of ignition parts swaps?) replace with OEM part(s) from OSO/Ebay replace with 500EFI setup (anybody done this swap? Parts interchange?) replace with Holley EFI setup Perhaps weld up the lower manifold if it's not too far gone. But being a salt water engine I put it far down the list. A cam and maybe headwork are on tap for upgrades but nothing radical. Aftermarket exhaust that is Silent Choice compatible might be on the list also. Primary goal is to be running again as quick as possible. |
Get a used freshwater setup off ebay or from the classifieds or swap shop.

z,
Just fixed one a month or so ago. If it is just badly corroded right at the inlet to the water passage, then it is a piece of cake to weld it up and resurface it. One key to doing the job right is to get a die grinder with an aluminum bit and grind away every bit of corrosion before you weld it back up. Any performance machine shop that does cylinder head porting should be able to fix it for you. Figure in the $250 range. Bill Koustenis Advanced Automotive Machine Waldorf Md |
Thanks guys. Still hesitant to weld on a salt water piece though. Keeping eyes open for a replacement while deciding on a shop. Gotta do some searching for MPI mods.
