OK I've been looking everywhere and doing research but just haven't found anything bout putting in a 351w camshaft Into a older 302 now I know you can do it on the 5.0 ho but I don't know on the older blocks.both are the older style blocks and there the same cams but one hs a bigger lift and that's what I want. Any help is appreciate it thanks!!!
it will go right in. the only change is the firing order it self. you will want to use 13726548 firing order with the 351 cam.
OK cool thanks bryant. Just wanted to make sure before I toss it in and cause chaos on a good engine haha
Ditto, there's no difference in the crankshaft of either as far as how the throws are positioned in relation to each other. The block has nothing to do with it.
How will the mileage be compared to a stock 302 cam? I was looking at 351 cam with a 260 degrees intake and 274 exhaust: part number D3OE-6250-AA
That comes up as a "82-84 5.0L HO" cam and is TINY with 198/208 duration @.050. Plus it has a very wide LSA for EFI stuff. Totally the wrong cam for a carb'd setup and not worth installing even if it was free, IMO.
lol.. If only Ford's parts numbering system always held fast and steady. In the real world they're hardly relevant to the actual dates they're used in. Google.. D3OE-6250-AA camshaft.. and see what you come up with.
Actually the wider LSA cams work great with carbs. I've run the F4TE roller in a 302 with a Ford A321 intake (the newer version of the old Cobra highrise dual plane) Topped with three different carbs (a mod'd 600, a 3310 750 and a 570 Street Avenger) this motor ran exactly like it had an EFI setup feeding it. With the 570, cold starts were made at 25* F without touching the go pedal to give it a pump shot, all you had to do was crank it a few seconds, then it would fire up and idle all on it's own without a choke. The powerband was smooth with no flat spots, from idle to 5500 rpms. A pure pleasure to run around town with a 4 speed and a 3.73 rearend.
The 82-84 HO used a marine cam grind. The F4TE I mentioned came in the 94-97 pickups and vans and later used in the Explorer/Mountaineer 5.0.
lol.. I thought I might pull you out of the woodwork with my response. It's all good and I won't get into our philosophical differences of proper cam design for these anemic heads again. This first post says it all about the cam and engine designer who worked on it. http://www.stangnet.com/mustang-forums/threads/found-this-on-craigslist-is-it-rare.775603/page-2
That's interesting, but it was Ford itself that started the rumor (?) that the marine cam being used in the HO. Wouldn't be surprising though that they pulle dthe old bait and switch on everyone. The same thing happened during development of the GT40 5.0 in the Cobra. The HO roller was tried but it too was dumped in favor of a redesigned profile(the GT40 roller) idle and torque. The wider LSA (resulting in less overlap) I think gives a stronger idle vacuum, thus allowing the circuits in the carb to respond faster. The Z cam I'm running is another example, it too has a wider LSA, it too has excellent throttle response, without seeming to run out of steam on the topend, where narrower LSA cams are supposed to shine.
Remember, the umbers on a Ford part are not a part number, they are an engineering number. I know the more experienced around here know that but some of the newer fans refer to things as part number when that is not the case. Want a decent street cam for the money buy a Comp Cams Hi Energy grind. They have always treated me well. SPark
There's nothing wrong with the HO cam. But there are better choices out there. It really boils down to what block you're putting it in or if in a flat tappet block, are you willing to spend the money to convert it to a roller setup ?
