I have 1996 f150 that i am converting to 4wd. I have a bunch of 351 parts ( aluminum heads, edelbrock intake msd dist) from a old projesct truck that got rolled and i was wondering if the heads and intake from a 351 would work on my 302 block/ what all would have to be changed or is it the same? any info would be a great help

I think you should send me all the 351w stuff you have to....inspect, yeah that's it. If you look up the part number on edelbrock.com, it should show you the application. I believe the heads and will work, intake should fit after the heads are swapped to the 351 setup

i want to put all this stuff on just i know they list different #'s for the 351 and 302. i think thats just because the ports are different

My knowledge on this subject goes back many years (late 60's early 70's) so I suppose it is possible what I am telling you is not applicable to more modern engines, but here goes. Installing 351 windsor heads on a 302/289 was a very common modification back then because the 351 heads would accommodate larger valves. But you cannot use the 351 manifold, the 351 block is taller and the manifold is wider. You need to use the 302 manifold, 351 head to intake gaskets but 302 intake to block gaskets. The 351 has a slightly different water jacket in the head and one additional bolt then the 302 intake, because of this, this set up will always leak a little bit of coolant. I don't remember for sure if the distributer will interchange but my guess is that it will.

chip nailed it on the head. The heads are a direct bolt on but due to the taller deck height of a 351 the intake will not work. You need to use a 302 intake and before you put the intake on you must put a bead of RTV around the port/bolt hole that you will not be using. ARP makes a nice set of head bolts for the swap that have a larger shoulder due to the 351 heads having larger bolts. They are not necessary as the dowels will align the heads so that you can use 302 bolts but if they are aluminum heads you might as well spend the (last time I bought a set) 105 bucks for the shouldered bolts. Never re-use head bolts, especially Ford head bolts as anything 85 and newer are torque to yield (i.e. good one time). Also, and I'm sure you already know this, don't bother with the front and rear intake gasket pieces. Simply make a thick bead of RTV and gently place the intake on the heads. Those end gaskets always either push in or out and I've never used them, ever. My dad and I have built quite a few race motors that usually turn over 7000 RPM for 25 laps and the silicone trick has never leaked. If you have any other questions PM me and I'll do what I can to answer them.

oh, you have to run the 302 distributor, once again, the 351 is taller so it won't work. You shouldn't have any problems selling the 351 stuff though.
