Message: [QUOTE="BrewTown, post: 1546587, member: 31811"] This is still a ways off, but, just for fun I thought I'd let you guys know what my plans are. I'm going to use an 03+ Expedition frame. Ideally 07+ as they updated a couple suspension geometry things. Not the EL. Before I purchase a donor, I will check frame height, but I'm thinking some of it may be visible under the cab as that frame is tall. Reason being: 4 wheel independent, rack and pinion, 4 wheel disc, and that wide stiff frame. How many classic trucks have that? The front axle is a reverse rotation 8.8, and CV axles. I'm thinking that the aftermarket should have some parts if (when?) I break it. This is the same as in F150s, and they are built as dessert racers with big tires and power... We'll see. Rear axle is a 9.75" (same as a Dana 60) with CV axles. Hoping with IRS, wheel hop won't be an issue, so parts breakage won't be too bad. Axles would most likely be the fuse. Transfer case, I will keep the floor shift NP271 behind a 4R100. Most likely do drive flanges in front, so 4wd will be a transfer case shift away. For suspension, they call them struts, but, I think they are really coil overs. Not really sure what differentiates, thought struts took the place of upper arms. This has upper and lower control arms front and rear. If needed, adjustable coil overs could be used. Obviously with different rates. Stock gear ratio I will use is the 3.31. With 32" tires, and the turbo setup I want to run, it should make for great street manners. Speaking of that turbo setup, I plan on connecting rods, so, might as well try compounds right! I believe a 364.5 in the valley, and a 476 maybe. May need larger LP, don't think so though. Really fast lighting for street is the thought. Gated around that HP to the LP. Dual HPOPs and 350/200 still. When the time comes, hoping ported heads and talking to Brian Gray about a cam. Heard good things. Like Richard Holdener says, better NA means better with boost! May try an air to water. One of the many challenges I will face, how to handle the wheelbase. The '60 has a 110" and the Expy frame is 119". I am 6'2", so adding a little cab space would be welcome, even if it's just under the dash/windshield. Adding under hood length would only help with a compound 7.3 also. Not sure how to make either look right, and bodywork isn't my forte... Another option is to just shorten the frame. Or cut down a long bed to fit. Still have a couple months of my house remodel before I can even think about any of this. Hung up my framing hat, and put on my plumbing hat recently. Sometimes I think life would be easier if I didn't know anything... Input is welcome! [/QUOTE]
