Thanks for confirming everything Chuck. I've got the Thermactor internal I believe and all holes are plugged already. Like you said, it doesn't matter I'm going to run no emissions and a non-egr intake. That's what I was looking for! Good info. I'll check out that site for parts. I've got another one for ya. If I were to re-use the 302 distributor, what do I need to change? The 351 is non-roller so would the gear be good on distributor? It's a Duraspark non-points type. Also, I know I need to wire plugs for 351 firing order which is_____! (since I'm picking your brain and being too lazy to google!) Thanks man!

Man that thing looks great. I had a 71 Bronco that I put a fuel injected 302 in it and loved it. The problem with running a Ford fuel injection system on an older bronco is hood clearance. I had to run a hood scoop and it looked stupid. Although it was really reliable! To bad I had to sell it before moving here. I loved how much room the thing had inside. You could actually bring everything you needed for camping and still transport three people!
However, this is my opinion, don't waste your money on a carb unless you get a real good deal! All carbs will load up to include the truck avenger. I put the Holley Pro-jection in my CJ a week before the annual run and love it! I’ve taken it to Crozet twice and the annual and LOVE IT! It has way more throttle response better fuel mileage and it makes a lot of the 4 wheeling obstacles easier since it’s not running rich or wanting to die on steep hills. Things that we just deal with when you drive a carb shod vehicle! However the thing that I really like about the Holley injection system is that you can raise and lower your engine RPM as you need to. This comes in extremely handy when you’re on hard obstacles with a standard tranny and need that third foot. I just raise the idle to about a 1000 and use the clutch and brake, no need for the gas. Makes me look like I’ve got driving skills or I have an automatic. I think besides gears and lockers it was the second best modification to my Jeep! Scott

The 289/302 distributor can't be used on a 351. The 351W block has about 1.3" more deck height than the 302, which moves the intake manifold up about 1" relative to the crank and requires a taller distributor to clear. My roommate may still have a spare 351W Duraspark distro, I'll check this weekend. I believe he had a spare fo the one on his truck now, and if so he'd probably be willing to part with it since we're switching it over to TFI along with the rest of the factory fuelie swap soon. If not (he may have already given it to another friend, don't remember), they're really easy to find cheap at UWI (er, PnP).
351W order is the same as the late 302HO (non-truck) firing order, at 1-3-7-2-6-5-4-8. Basically the firing of the second and third cylinder pairs are flipped relative to the non-HO 302, which was 1-5-4-2-6-3-7-8. The original 289/302 firing order put a lot of torsional stress on the front of the crank, which is why they used the flipped order on the 351 when it was created, and later on the HO 302.

You guys heard of AFI (Affordable Fuel Injection)? They build kits at a reasonable cost. I've done a lot of searching about different carbs and pretty much un-convinced myself that a carb would be even satisfactory for my needs. By the way, Chuck, I am going to get a distributor from NAPA (they're $60) and it's plug and play with my Duraspark. Thanks though...

I looked at their site. They’re more expensive than Summit with the Holley Pro-injection. I’d go with Holley through Summit! It will be on your doorstep in two days and it only took me a day to put it in. If you have 5/16 or bigger fuel pressure and return lines you can be done in about 3-4 hours. The kit is super easy to install. It’s easy to troubleshoot too. Scott

I've just heard a lot of bad comments about the system (Pirate-most of the time I really wonder if many of those guys are just talking out of their a@#$s!) so I'm doing some more research on the different set ups out there and their prices. I'd like to check out your installed system if I could sometime!

Come on up any time. I'm always around! I’m trying to finish up my Wrangler project up on 42s and coil springs by the end of Feb. You’ll like the Holley set up it’s a really nice harness, which makes life easy! Scott

I wanted to correct a little tidbit in my earlier post on the air system ... The info in italics above is incorrect. I took a better look this weekend when I was dropping the engine back in the frame. The thermactor passages are drilled through the holes on the back of the head that are highest, not lowest, off the firedeck, but still toward the exhaust face. The ports should be connected to the thermactor passage through the roof of the port, not the floor, but I didn't remember to check on this before I bolted on the headers. Otherwise good to go, I just didn't want to leave incorrect information where someone might come across it later.

If you go with either a points or Duraspark distributor, I'll see if I can find it, there is a drawing on how to use the duraspark (or points?) distributor with a GM HEI module for better ignition, for cheaper than getting an MSD or otherwise. I think it's somewhere on www.ford-trucks.com or something. I'll have to look again. The main thing with using either full Duraspark or the HEI setup is, that you have to make sure, especially with the HEI, that you heatsink the module. Otherwise, you burn it up and die. I'm sure you can find the info a la Google or whatever. There's lots of different sites that have info, I'm sure. Cant' wait to see how she looks with the D60 and 10.25 full-width axles under her. I'm guessing you'll be planning on having her on the trails sometime early next year or so? EDIT: Duraspark mods. This one uses a Duraspark distributor and control box with a TFI coil: users3.ev1.net/~bmarr/duraspark_ignition_upgrade.htmThis one uses a Duraspark distributor, GM HEI ignition module, and a TFI coil: www.epiccomputer.com/dale/jeepjunk/tfihei/shuffjb/prestolite.htm

When you're ready for wrenching help on removing axles and putting the new ones in... lemme know, Dave.

I'll keep my eyes peeled, Dave.... you may actually find one at P-n-P.... I saw some older trucks and whatnot there. Am planning on hopefully not being robbed of the radiator that would have been in hand had I had a @#$%^&*! knife with me
