The casting procedure is the same for the M series as Clevelands, IOW thinwall. Casting #s for the blocks are found under the right rear cylinder bank. The only known issue with the M series are blocks cast at the Michigan Casting Center prior to 1977 which crack in the intake valley water jackets. Look for the M C C cast into the block near the oil pressure sending port. The magic date is 7C01. Cylinder heads on the M series are virtually identical to Cleveland 2V series. Many people prefer the Cleveland heads because of a thicker casting. They also have a slightly smaller combustion chamber volume, 76.2cc vs 78.4cc. I have 1974 Cleveland 2Vs on the 400 I'm building. Port design is the same. All this information applies to the American M series and Clevelands. I understand that you guys have a different design Cleveland head than we do. ----- Original Message ----- From: Tony Travers To: Sent: Tuesday, March 14, 2000 7:03 AM Subject: [perf-list] 400m artical - David Resch > > > Read an article written by David Resch on 400 motor.

Yo Tony: I too have heard about problems w/ overboring 335 series (351C/351M/400) engine blocks, but not until more than 0.030" overbore. I have also heard about problems w/ blocks/heads cracking, but again, I have never seen that personally. Others may have different experiences, but that's what I've seen. I wonder if the alloys and casting techniques used in Australian 351C blocks/heads are different than those used for US engines. This could be part of the problem. I have also heard rumors that the Aussie blocks/heads are better castings, but I don't really know. I have heard that a lot of people in Australia run their vehicles w/out anti-freeze/coolant, and that would certainly cause corrosion and erosion inside the water jacket over several years usage. At any rate, if the 400s were not cast in Australia, they would probably be different, maybe or maybe not better. >2. 400's a rare here in Australia, How do I identify the >age - year of manufacture. Date codes are located in two places on the block. The casting date on Michigan Casting Center (MCC) blocks is located in the little recess at the back of the block on top, in the area of the oil pressure sending unit. Some Cleveland Foundry (CF) blocks do not have the casting info there, though. All M-blocks have the original build date (the date the engine was assembled at the factory, usually about 10-15 days after the casting date) stamped into the front cover mating surface on the front of the block. Ford engine date codes are in the format nXnn, where the first number n is the last digit of the year (7=1977), the letter X is the month (A-L, A=January), and the last number nn is the day of the month (01-31). >3. Are the cylinder heads the same in combustion chamber >and port designs as 351c 2v. If the chamber is the same >what size would they be 72cc?? I have no first-hand knowledge about Aussie Cleveland heads. I'm told the general design of the ports and chambers is the same, but some Aussie Cleveland heads used slightly different chamber designs/sizes than US heads. I've read that since some 302 engines in Australia actually used the Cleveland head, there is an Aussie Cleveland head w/ 52cc chambers. This is way smaller than anything made in the US, and on a 351 or 400 it would produce outrageously high compression. There are no US 335 series heads that are advertised to be 72cc. The only US heads that have the small (2V) ports and valves are the 351C-2V (76.2cc) and the M-block 351M/400 (78.4cc). Chamber sizes on various US 351C-4V heads are 62.8cc (early '70-'71 4V heads), 66.1cc ('71 Boss 351 heads), 75.4cc ('71-'73 regular production 4V heads), and 78.4cc ('74 4V heads). This is as reliable as I can get.

You might be able to drill a small hole in the rear of the tranny flange right behind the alignment pin, and drive that one out with a small long drift pin. That is the approach I'd take, I think. Someone suggested visegrips, but I've had those pins stick so tight I thought they were part of the tranny. Might be worth a try before getting out the drill though. Lots of the work I've done on vehicles I've not been absolutely sure was going to work until I completely buttoned everything back up and tried it. BTDT many times over these years. Will be doing it again very shortly on a couple of projects I have. Never let that slow me down nor discourage me when it did not work(and there have been times when it did not work). Good luck.

Does anyone know a reason why it wouldn't? Thanks. ------------------------------ Date: Tue, 14 Mar 2000 17:55:40 -0800 (PST) From: shane san miguel Subject: Re: 71 distributor in a 85 If the 85 motor is a roller cam then the distributor gear from the 71 would have to be changed. I think to a bronze gear. Double check that though. Otherwise, you shouldn't have any problems. If the 85 is a flat tappet cam that is.

I got a few questions, such as cam selection, compression ratio, cost of conversion and so forth. With the cost of gas goin through the roof, Im looking into alternative fuels. Ive already got a motor goin together, so Id like to find out what I would need to keep the Hp levels up. Its a 460, .030 over with a pair of 68 429 heads. Pistons are hyper, and the cam Ive got is a comp 268h. I know the heads need super hard valve seats, but after that I get lost. Also, is there a setup out there that could handle a high HP 460? I dont wanna starve the motor, even if I am savin $$. Any help is greatly appreciated.

With the exception of how ever much 'bypass' the engineer(s) designed into the powertrain. As an example Kim's Mercury usually runs right around 195 in normal conditions but this winter running 75 MPH for a 1/2 hour or so with the OAT at 20 Degrees resulted in a cold engine and no heat (Brr!) If the temp. here was often that low I'd think of putting a washer or a ball valve in the bypass hose to restrict the flow somewhat. > > By the way, some > > radiators are so efficient that, with the thermostat removed the engine will > > NEVER reach proper operating temperature in winter. Actually MOST radiators.. by removing the t-stat entirely you've dramatically increased the amount of coolant that can flow compared to the restriction the t-stat imposes. (Especially in import engines that use the full size t-stat with a 1/2 sized hole.) Froze my butt last winter in the B-2000 as the PO had removed one. Finally replaced it about the time the WX started warming up. ;-0 (And this on the original radiator with coolant that looks like beef kool-aid at 206,000 miles so I'm sure it's not at it's most effecient..) > > ahh you're contradicting yourself here me friend.. even the best > radiator in the world can't cool anything unless there is coolant flowing > through it! Gotta remember that bypass hose and the heater core. There's always some flow going on even if it's not readily visible at the radiator neck. Others have mentioned it, but with a 50/50 coolant mix and 15 Lbs. of pressure the boiling point is well in excess of 240 Degrees; some GM electric fans do not switch ON until as high as 235.. (Assumes the owners maintain the cooling system well doesn't it! I prefer Mopar's philosophy of turning it on at 212.. I think Ford is in the 220-225 area.)
