Trying to decide on future motor build
Alright this isn't anything I'm doing right now but once I make my decision I will start piecing it together. I plan on staying supercharged since my head unit will go as far as I ever plan on taking it. So here is what I'm trying to decide on.
Do I want to stay 302 based since all my accessories will work with it. Go with a 331 or 363 port my heads, intake and raise the boost a little.
Or
Go 351 based with either a 408 or a 427. In this case I would need different heads, intake, headers but I would make more power on less boost and more torque. I can always sell my old setup to make up for the cost of the new heads and intake.
Opinions are welcome. I'm just undecided and keep going back and forth on this. I want to start buying parts here in the next couple months. It will not be a fast build since I'm in no big hurry.

Boost technology has come to a point where the big inch Windsors aren't really needed, unless you're looking for the baddest of the bad. My favorite combo has always been the 331 (more favorable rod angle), and built right, with a little boost, would be all I would ever need in a lightweight Fox.
And on that note, I need a Fox I can modify, damn it! I love my '82, but it's entirely too original to start cutting up.

I would go the 351 route since the factory block is stronger. Assuming you are not going to buy a dart block. But if you are then hands down go with a 347 ci 3.25 stroke 4.125 bore.

Dart blocked 363 with a Brooks kit. If you're going to do it, go big.

I wouldn't build either without a Dart block, I'm not dropping the coin on a forged internals without a strong block. Don't want to have to do it again later if I turn it up.

I have been thinking about that as well. But I already have a good blower. Might build it and run the supercharger for a while then drop the coin on a nice single setup.

Once I do the build I will sell all my old stuff to recover some of the money.

Is he using a factory 302 block, R block, Dart block?
If you already have a good aftermarket or R block, then its hard to justify the swap to a 351 based motor. If starting from scratch there is ZERO reason other than class racing to stay 302 based.
If you have a good block, I vote 363 with an 88mm minimum.
If you go 351 I vote 427+ci with twin billet 76's
Orrrrrrrr ERL 427, LS based, twin 7675s

Don't currently have a dart block, that's why I'm having the debate. I am starting from scratch.

Then go 351 based without a doubt

I'm sticking with a ford motor. Not jumping ship, it's not that I don't like ls motors I just want it to be a ford.

Good man. One of the fastest cars in Dallas has a little Ford motor in it, so don't be worried.
I'd do a 427-454 stroker 9.5 decked Dart. You will want new heads and intake manifold with any sized motor you go with.
FYI, besides the headers/and a/c bracket (you already have a cowl hood), its $100 bucks more to build a 9.5 vs a 8.2 (what my dad was quoted)... All things equal is about 80-100rw difference. (454 vs 363 for instance), not to mention the monster torque differences.

He was talking to me. I know Chevy motors are cheaper to build but that's not what I want. I've built a blown 408 in a sportsman block years ago so I know they can be expensive but it the way I'm going. Also why I'm taking my time. My wife is going back to school so I can't just fork over the money at one time like I would like to. I'm going to get a plan figured out and start buying parts. That way when I get all the parts I can get it started
