351W EFI Long Runner Intake under STOCK hood
 

I haven't done it yet, but I am going to get my 351W with a TFS EFI intake under my stock hood. So far I have planed, Drop Motor mounts, Drop K-Member, Milling a 1/2" off each of the upper and lower intake mating flanges. I don't know if it will work, but if anyone has any suggestions I'd like to hear them!

You will be using the 351 lower with the R/351 upper. The R/351 has a short runner and the bosses on the under side for vacuum hook ups could be an issue. The driver side injectors and plugs 'may' be an interference problem. They are an issue on the 302's with aftermarket fuel rails because you cannot turn/twist the injector far enough to get it out of the way. If using stock rails this should be ok. Some clearance work may be necessary.

Also get steeda's extended ball joints to get the A-arm angle back after dropping the K-member. Also the swaybay may have interference with the front sump after dropping the mounts. Maximum Motorsports has some type of sway bar relocation to move the sway bar forward a bit.

Overall I like your idea. I would like too know how it turns out. This is the kind of task I might take on myself. Very challenging and it makes you think and rethink and come up with new solutions that you can be proud of.

Good luck.

Just an update to this thread. LOL

I've been driving around for 21 years with the 351W, now a 408W under the stock hood. I ended up using convertible motor mounts and spacing the k-member with 2" steel tubing. Speaking of which, I should check those bolts. 21 years is a long time for a grade 5 bolt and lock washer.

Not that anyone comes to this forum anymore anyways.
