I'm looking to try and swap my 302 out for the 351c 2v motor. I will trying to do this the way most do the 351w swap and use all the Fox fuel injection stuff. This is my daily driver and I am only looking for a modest 300 wheel HP for now. Please do not turn this into a W vs. C debate. I started this to hopefull get some advice from experienced Cleveland owners, and to add to the data base of information on this site.
From a lot of searching this is what I think I need. Please correct everything that is incorrect.
1. Mounts, I have read that the stock 5.0 mounts work just fine. So I plan to buy a set of poly bushings and re-use my factory Fox mounts.
2. Intake, The motor has a decent offenhauser intake on it currently. It's not the greatest but it will do for now. I have a plenum I made a few years ago similar to this one;

I plan to use that with the same BBK throttle body that is currently on the car. And measure the distance between each fuel injector, then drill and weld a bung for the injectros on the offenhauser intake. Hopefully being able to use the stock rails as well.
Trickflow makes a bolt on intake, but at $700 alone, it's to far out of my budget...
3. Headers. I can not get a clear cut answer on which set to use except for the Headman headers built for this swap. But again, at $700, it's just to far out of my budget.
4. Distributor, A 7.5/460 dist. should be a direct bolt in swap. I am not sure if this is true and if there is any wiring involved with it? Or does the Fox harness actually plug right in...?
5. Oil pan and pick up, I have come to the realization that I will have to pony up the money for a Moroso or similar pan here. Dosn't seem to be a way around it. But, I will be using a Qa1 tubular K-member. Will the stock oil pan clear with this K-member?
*I will be using the oil resrtictors from PME and a high volume oil pump. The insurance is well worth the price here to me.
6. Radiator hose, Both hoses need to me modified or replaced with another set? Not to much info on this...?
*I have the stock Fox radiator and fan right now. It cools my car easily even in the Florida summer. Do the 351c tend to run hot at all? Will an upgrade be needed?
7. Fuel, Are the 19lb injectors at 41psi plenty enough to feed my modest 300whp goal? I also have a 255 walbro fuel pump in the car. I have seen a few 302's with the stock 19lb injectors in the 300whp range without a problem.
Other than maybe extending a few lines and wires, is there anything else I need to look out for?
There are so many "How-to" write ups for the 351W, but I can not find a single one for the Cleveland. Giving the C is a preformance motor and the W is a truck motor, You think this would be a little more common. But this could be the definitive guide to a 351C swap how-to.
