Well, the good news is that I got a "top 20 mustang" plaque at the Fun Ford Weekend at Englishtown.The bad news is that on the way home, going north in route 9, I was engaged in a little "comparative acceleration" when something let go in the engine. The noise was pretty bad. The engine died and I had to force the car over to the side without power steering or brakes. The engine would not turn over at all. Not sure what went. I was expecting to see parts hanging down when I looked underneath, but I didn't see anything, not even any fluid leaking. I don't think it was the clutch, I can still push it in and it fells normal, but the engine will not turn over with the clutch in. That's the first time I've gotten stranded by the car (since I got it 11/1/97). So, I've off to visit L&M tomorrow night. I was going to rebuild in the fall, so it's just moved up. I hope that I didn't damage the block or heads so that they can't be reused.

Not Ray, actually Randy. (71 not 7D)I was going to do a 351C->408 stroker rebuild al la 7DMach1 later this year, so it's not that much of a bummer. I just hope that the block/heads are OK. [This message has been edited by 71Mach1 (edited 06-02-2004).]

Bummer about the engine. The good thing is these things always give you an excuse to upgrade. You will love the 408C. ------------------ Ben Grabber Green '70 Mach I 351C 4V Robbin Egg Blue '79 Fairmont 408C 4V, best time to date is 10.50 @ 125mph

I hope it's not too bad. But my experiance has been that when it wont turn over, generally something is broke really bad inside.

In my past experiances, one or both of the above are junked. I hope I'm wrong, but generally if something breaks bad enough to stop it from turning over, it broke other, more important parts also.

Met with Michael Rauscher at L&M engines last night. I was very impressed. It's great to find someone who really cares about the quality of their work. We discussed the basic plan to stroke to 408, solid lifter roller cam, roller rockers. He will be designing a custom cam grind based on flow data and measurements from the heads. I'll provide more info as the build progresses.

Randy, sorry to hear that the motor has a major problem. Like Dan said, it's probably one of the valves either lost a head or dropped. If I had known about that problem when I built it, I would have used a higher performance single piece/single groove valve. Guess the Manley replacement valves aren't up to the kind of task they were asked to do. FWIW, it is almost 10 years to the day that your 351 was first fired off. Man, that was a great day...

Drop off at Glaziers is scheduled for 6/25.The engine should get to L&M shortly after that. I expect the build to take 4-8 weeks, but it could take longer if I need to find new heads or block. Glaziers is going to re-do the engine compartment, that's the only part of the car that has not been really re-done and it's probably the weakest part in car shows. A couple of things I'm going to talk to them about. 1) custom built hood. If I need more hood clearance (and maybe even if I don't) I would like to get a custom hood with the center section of the 71 ram air hood raised. I'm not talking about the cowl induction fiberglass hoods that have a bow tie type raised section in the middle. What I want is the entire raised center section of the 71 ram air hood raised by 2-3 inches. This increase would be where the raised section is now in the front and sides, just with the rise going higher and the openings being larger. I think that would look really cool. I would rather have a steel hood (would probably use a re-pro rather than cut the NOS one on the car) but it might have to be fiberglass. For the steel one you would have to cut the center section out and the add material on the front or sides. Not sure if this is feasable cost wise (I'm sure anything can be done with enought time and money). The other option is to go with a glass hood, not sure if any of the makers would be up for something like that or what the cost would be. Any ideas on this?? 2) Back halfing the car. I was thinking of some form of mild tubbing and a 4 link. I don't think there is anything made for this car, so we would have to find the closest thing and make it fit. Not sure about the inside, the back seat/trim might have to be modified. The current rear could be narrowed. I have a problem with the leaf springs sagging, they were rearched, but they have sagged over the last two years with the drivers side down much lower than the passenger side (since it's usually just my 250+ rear end in the car). My wife was not amused when I suggested she needs to ride with me more to get things back in balance. I think there might be more options with the 4 link interms of controlling the rear height. I want to run 15x10 (at least) on the rear. I can get Magnum 500s in 15x10 and that would look pretty cool under the rear, but I want to keep the tires mostly under the fenders. Anyway, these are some ideas I've been kicking around, comments are welcome. I'm not sure if either will happen, but you've got to have some plans in the works or it gets kind of boring.

Being a 71 Mach owner myself, I think that if you start hacking up that car into a resto mod vehicle you will regret it in the end. There are not many 71-73s in the shows out there as it is let alone true Mach 1s and if you start modding too many things that make it a Mach in the first place I think it will be frowned upon more than praised. Please dont take any of this offensively, Its just that everytime I see a Mach that has been done this way it makes me wonder if it is really a Mach or a fake. Over the course of time mods like this will badly hurt the resale value of the car. If you want a race car, rescue a regular 71-73 from a salvage yard and build away

Don't worry, it ain't a real Mach 1. (look at the pics and see if you see what gives it away).Started life as a LIME green sportsroof with 302 2V and an automatic. Much better off the way it is today. Re-sale value is not an issue. I will never get out (monitarily) what I put into it and have no intention of ever selling.

Dropped the car at glaziers on friday. The engine should be at the builders early next week. Then we'll find out if the heads or block are damaged.Talked about some options for the engine compartment. Perhaps painting the bay body color (grabber yellow) with a flat overcoat.

As far as making room for more tire, I have done this on my '71 Torino. Got 15x10 wheels with 325/50/15 tires to fit with PLENTY of clearance. Still used leaf springs, just moved them inboard of the frame rail and made a new rear subframe. Details left to do are install the trunk floor and gas tank, and finish up the pass side wheelwell and seamseal the whole job.Since the 71-73 Mustangs and -70-71 Torino share so many parts and designs, maybe you could get some ideas from my project. This is a link to some pics I have taken so far in the process. http://groups.msn.com/MyFordandMercury/gregs1971torino.msnw?Page=1 Good luck!

Got these pics from the engine builder without much comment about what they mean.Anyone want to analize? Looks like a broken valve and piston? The major question is are the block and heads ok? He said they would let me know after cleaning and Magnafluxing so I'm assuming he didn't see anythying with the heads/block right off the bat. http://home.comcast.net/~jodiseth/351C-001web.jpg http://home.comcast.net/~jodiseth/351C-002web.jpg Got this update.... The exhaust valve broke (overheat (coolant or combustion) and/or detonation) destroying the piston. Usually this failure is very deadly, breaking the block and/or head. With a casual examination the block and head look OK, although Magnaflux will be the final crack check.

Typical 351C broken valve syndrome...NEVER use stock valves in a 351C. They are junk. Their heads tend to pop off and junk the engine. Always use one piece stainless, single groove valves... even on a stock rebuild! What your pictures show, is how 95% of 351C's with stock valves die. The lifters pump up, (when hydraulic cams are used) the valve tags the piston, the head pops off, and the engine is junk. Run a small solid cam and good valves, and the engine will live a long, happy life. Now you know...

The block is being drilled for 4 bold mains (just a little insurance), 4340 forged crank, H beam rods.The builder says the heads need a little port work to hit our target (500HP) based on the flow data. He would like to use a single plane intake manifold, probably a torker, but he would like something more like a victor (which they don't make for the clevelend?). Any recommendation for a more victor-like intake for the cleveland??? The other options besides the Torker seem to be Holley Strip Dominator 351 C-4V (300-13) - high rise air gap open plenum single plane with Holley carb bolt pattern
Weiand xcelerator 4v Do these have bigger runners/plenums than the Torker? That was what he meant by "more like the victor". Also, will I have hood clearance problems?? I don't really like the fiberglass hoods for the 71 mustang, looks too much like a bow-tie cowl induction hood. I'd like to see one where the entire center section with the scoops is raised. I don't think anyone makes that, not sure how easy it would be to fabricate. Also, he wanted bigger headers, I currently have the Hooker Competition #6915, with 1 3/4 primaries and 3 inch collector (I think those are the numbers). What are other people running with their 408s?? If I'm reading the hooker web page right, it looks like 6211HKR will work with a 71 mustang with manual. It has 2 inch primaries and 3.5 inch collector. anyone used these on a 71 mustang??? thanks for any help!

That's the best one available for all out racing. But, they can be rather tuff to find, or expensive once you find one. The plenum on it is huge. Don't count the Torker short though. It works really well on a cleveland, much better than on other motors, especially if you have room for an open spacer and do a little grinding in the plenum area. Hood clearance shouldn't be an issue with either.
The Weiand Xcelorator isn't very good for the 4v heads, and would be my last choice for anything.

I can't imagine why you'd want to back half the car. Is this just for looks? If so that practice is all but dead, not saying you'll be laughed out of car shows but with so many cars running 8's on tires that fit the stock wheelwells i see no useful purpose in this unless you plan way more than 500hp. The 10" wide wheels fit easily in a 71-73 Mustang. A 67-70 housing and axles or even axles with the 1965-66 width allow for a very deep-looking 10" wheel.

back half probably won't happen. they are going to give me a little more room in the wheel wells, as you say should be able to fit 10in wheels with only little sticking out.If I did it it would be mostly for looks. I do like the look of really wide tires under the fenders.
