    I bought it off a junk Maverick for $250. Doug Bauer picked it up for me and I will pick it up from him at the next Roundup.

    I already have a thread on my Comet build, although its at a stand still now, but I will continue it when I get back on it. Hopefully early next year. I'm in the middle of renovation my downstairs and I need to finish it first. My Comet thread is here:

    So do you HAVE to go with a Mustang II front end to do this swap or can you just mod the shock towers. Im thinking cut the shock tower down to lower the upper shock mounting point about 6 inches and then cut it back the same way you would if you were just notching the shock towers. Would that give enough room for a Coyote 5.0?

    I've already got plenty tied up in my Total Control suspension. I'd prefer to keep it. Besides, the Coyote is a pipe dream for me. It was just one of those "What if?/Wouldnt it be cool...?" kind of thoughts.

    :yup:

    I have a 4.6L in my van. Doesn't smoke except a little puff when I start it warm. Tiny exhaust tick when I start it cold, goes away after warm-up. Doesn't leak a drop, plenty of power, holds good oil pressure, smooth as silk and habitually moves a lot of weight. It's completely reliable and shows no signs of giving up. 352,000 miles. It's on its third transmission, but the engine's original.

    Doesnt that kit allow for mod motor swaps? And in a few years i think they might become affordable. Like the LS engines did. :)

    No. The Total Control Products Coil-Over Conversion Kit is a direct bolt in kit and keeps the current suspension geometry with Shelby upper A-arm drop. The upper coil-over mount though are about 7" tall and could be eliminated if the shock towers were not there. That might allow enough room for a mod motor swap.

    Have you guys seen this mod motor yet? A little bit on the insane side but...

    one of the NPI engines could be had for cheap, ad the PI heads, intake and cams to it and wake it up with the compression boost

    Wow :yikes:

    I don't know anyone who could afford that - I guess if you were a Wall Street speculator you could afford 2 or 3 and pay cash for them :taz:

    Just a thought but I wouldn't bother with any of the 2 valve modular motors. They are almost no better than a push-rod 302 with a decent set of GT40 heads and fuel injection. They pretty much all were dogs except for the later ones and even then they only had 260 HP. If you have the MII suspension in there get a 3 Valve (300 HP) or a Cobra/ Mach 1 4 valve. (310+ HP) Even the Mark VIII 4 valves (280 HP) are better. Plus the 4 valve motors look 1000 times better under the hood of a muscle car. Just my opinion. I saw 2 Mark VIIIs at the junk yard with 4 valve mods last time I was there.

    Trick flow has some aftermarket heads for the 2 valve, there's plenty of build threads showing 500HP cheap builds with them. Plus they are way easier to find than the 4V ones.

    They're great engines, I had one in my old T-bird. I also did some measuring and you can swap them in by just dropping the control arms 1.5"s, so you don't even have to swap out the suspension.

    For a cheap build I wouldn't even build a N/A 4V, way better to just throw on a cheap turbo kit on it.

    But I agree the DOHC 4V look BAD ASS! I've always wanted a navigator engine to stuff into something.

    It's just the potential of the 3 or 4 valve is what makes the mod motor better than the push-rod 302. There is no real power difference per dollar spent on the 2 valve motor vs. the old 302. They have a slight RPM advantage that is limited by their small valves and small bores. They just cant breathe as well. I was always mad at Ford during those years. I thought every 96 Mustang GT should have had a 4 valve motor. The GT gets the Lincoln 280 HP version and the Cobra got the 305 HP version.

    That said they are good reliable engines. They are Fords after all. ;)

    I've always wanted to build a car with that Mark VIII engine. It's a great block like mentioned before and you can upgrade the bottom end easy enough with a Cobra forged crank. Plus, the intake looks absolutely wicked in an older car when they are painted or polished up. They sure are alot prettier than the 2V. I was trying to talk my Dad into a Lightning 5.4L supercharged engine for his F100 project but he wouldn't bite because he said: "It's just an UGLY motor!" If you want alot of trouble free miles, the 2V is the way to go tho. down here they use the old worn out police cruisers for taxi's, usually with over 250K miles on the odometer. Stick some valve stem seals and chain guides in them and go for another 250K.
