I remember on a episode of Trucks the bronco named Project Crazyhorse had a 302 bored/stroked to a 380. I'm trying to remember the name of the company that makes that stroker kit. I have reason to believe the host used a Ford Racing 302 siamese bore wet sump block part number M-6010-S302 because the specs state that it "Can be bored/stroked to produce 380 cu. in." and it has a deck height of 8.700". So do any of you recall the manufacturer of the stroker kit used in that project?
Oh..I see. I don't know how I got it into my head that it was a 380. Thanks for the information though. It's interesting that he picked a 302 for that project. I guess it can be a good truck motor in some applications. Speed-O-Motive makes a 355 stroker for the 302 and a 427 for the 351. Would a set of heads like Windsor Jr.s or the AFR heads have to be machined to accomodate the larger bores? I was excited to find out that Ford Racing makes a siamese bore 351 that can be bored/stroked over to a 454. The best part is it's alot less expensive than Dart blocks and likely as durable.

I doubt they are as durable as the Dart blocks...although I'm no expert.
I can see using a stroked 302...why not...you'll get decent torque out of it and the bronco isn't that heavy where you need a boat load of torque...that powerplant was a pretty good choice for that vehicle IMO.
Yeah I'll likely go the 351 route since it's so easy to do that swap. I'd still have to keep with the 302 firing order unless the Tweecer can change that with the EEC-IV. I allready have the FMS MAF kit now I just need a tranny controller like the Baumannator.
The FMS siamese 351 block is no light weight when it comes to engine blocks and it's still pretty darn pricy but not almost $3 grand like the Dart blocks. It has four bolt main caps and it is reinforced in certain places. I believe it's about $1700 or more.
My goal at first is 500 but then I'll want to move up from there. I don't think a production block is good for what I'm wanting to do.
I am insanely interested in the 427 stroker kit that Speed-O-Motive makes. The production 351 blocks likely lack the bottom end for that. The compression ratio for that kit is also pretty high so I'd likely be running low boost if I ever decide to get a turbo kit from Silver State Motorsports. I decided I'd want to go with the Windsor Jr. Lites since they have larger intake runners and combustion chambers than AFR's largest emission legal heads. I still havn't decided on a cam just yet. Both could go on the 302 or 351 depending on which I decided to go with. (Correct me if I'm wrong about that last statement.)
Honestly I don't have a problem with the firing order if a 351 block can work with it. From what I understand cams are interchangable between the 302-351 just like cylinder heads.
A stock block would take a 427 kit, but if this kit is going to give you high compression, it'll be better to lower the compression for boost. Consult some more experienced people about that, it's important.
The cams are interchangeable as far as I know.
I was speaking in rwhp terms, so fwhp the block will take about 700 and it'll start crying. The 302 is more around the 500 fwhp range before it starts crying. But, some do better than others, so be conservative. It sounds to me like an aftermarket block is going to be a good choice for you...protect your investment...that block lets go and you'll loose it.
I've never really been a big fan of the Ford hi-po blocks...people seem to do better with other aftermarket blocks.
.... I'd still have to keep with the 302 firing order unless the Tweecer can change that with the EEC-IV...
You might want to download a copy of caledit and see if someone can send you a binary for the computer strategy and calibration you intend to use. I know for a fact Tweecer can change the firing order on the A9L and A9P.
I don't understand why you'd even want to change the firing order...
I'm assuming you'd be using MAF, probably mustang computer, to run this engine. Those computers have the 302HO/351 firing order. You'd just need a cam with that firing order, and arrange the spark plugs to that firing order.
The rig is a 1991 F150 Custom single cab with the 8ft bed. It has a 302 and a E40D. The MAF kit I'm using is the Ford Racing Performance Parts kit designed for the 5.0 trucks with the AOD tranny. It is also designed for the 5.0 firing order instead of the 5.8 firing order. Since I have a E40D I need to get a standalone tranny controller. Buying that and wiring it into the factory harness would be cake. The only difficult part would be setting the shift points. Since my MAF kit is designed for the 302 trucks I'm assuming that the injecters spray fuel in the distributer sends spark to the cylinders in 302 trucks. If this is the case then I would rather change the cam or learn to digitally change the firing order with the Tweecer or another third party software rather than cutting into the wiring harness supplied with the kit. That was a $760 investment with shipping.
Your firing order starts with the cam. Whatever firing order the cam has needs to be used. Whether it's the 5.0 truck or 5.0HO/351 firing order. Then, you put the spark plug wires accordingly so the spark will be in the right order, and you can change the wiring on that MAF kit to change the firing order of the fuel injectors. Once all 3 components are matched, you're good to go.
My MAF kit originally had the 5.0 truck firing order, but was re-wired to the 5.0HO/351 firing order.
