There hasn't been a whole lot of progress on this, but I have made a few changes to my plans. Yesterday I called Factory Five and made some order changes.
1) I changed from a 302 to a 351 (more on that in a bit). The motor mounts for this are the same, but that changes the exhaust. For the 302, the stock option is a "J-Pipe" to connect factory or bolt-on exhaust manifolds to the side pipes. For the 351 you have to use their 4-1 headers, which bolt up to the straight pipes. I was fine with this since that was going to be an upgrade anyway.
2) I opted for the 3-link rear end. The 3-link is universally praised as better than the 4-link in comfort and handling, with the 4-link only being considered better if your goal is drag racing. Since that's not my goal, the 3-link made sense.
3) FFR sells an aluminum racing radiator that's designed to fit right in, is brand new, reasonably priced, and has more than enough cooling capacity. Sounds good for what I want.
4) I ended up deciding to go with powdercoating on the frame. Few reasons for this. First off, they're running a sale and I needed a bit more to get me above the next threshold which would take the discount from 20% off all options to 30%. That extra bump made it essentially free. Also, I decided that while I think painting the frame would be a better result long term (and black is not my favorite color), this isn't a car that's going to be used on salty roads, so it is rather indifferent. This way I can get right into building the car.
One guy on the Factory Five forum made me a very nice deal on a set of SN95 spindles and new front brakes, so those are on the way.
I'm still debating what to do on the rear. I'm starting to get some bites on parting out the donor car that I bought for the engine (really the heads) and sold the AOD out of it this morning. I'd rather sell that donor car as a whole, but I haven't been getting bites on the complete package yet. We'll see how the rest of the parts sales go. Basically if I decide to part the thing out, I figure I'll rebuild the rear end the way I want it. If I can get a bite then I'll buy a rear out of a later car that already has disk brakes and go with that. In a lot of ways I'm leaning towards rebuilding the rear on this one, just because then I can go 31-spline, all new center, axles, and disk brakes, etc.
On the engine, I decided to go 351. I thought about this for a while, but decided it made more sense for what I wanted. Biggest reason is I like torque. More displacement = more torque. I really like insane levels of torque. These heads were really more appropriate for either a high-revving 302 or a 351 having the bigger valves and bigger intake runners. The concern I had was that I might end up with an engine that really needs to get wound up to work. On a car that's primarily going to be driven on the street, I don't feel like that will end up being a lot of fun. Additionally, it might be fun to make a 7,500+ RPM 302, but from reading up it seems like on a stock block that's asking for trouble.
Since the 302 block I had is basically toast and I don't expect to use the intake it came with, I need to get something else anyway. Looking at the economics, getting a 351 short block makes a lot of sense built with the pistons I want to use. The goal will be a high compression 351, which I think will be a lot of fun and make more torque and probably more power. The 351 weighs more, but between the aluminum heads and intake I'll be using, I don't think the extra weight will be tremendously noticeable vs. a 302. People on the forums said that there wasn't necessarily a huge feel difference between a 302 and a 351 from the engine weight.
Another decision I've made is that I'm going to put electric power steering. This is a common thing done on the Cobra using electric power steering out of some GM vehicles. The nice thing about it is that you can adjust the assist with a dial, so you can go from max assist all the way down to zero. That works well for what I want since when Laurie drives it she'll probably want more power assist and when I drive it I'll want almost zero.
The build date is September 8th, so I should have the kit at my house by the end of September.
