    VIN Border For 69?

    The 69's should have scroll/border but they were reversed stamped on late 69's so the letters were raised instead of recessed. http://www.martiauto.com/fraud/VINTag.cfm Here is another early tag with the correct rivets. . This is a late 69 tag with the raised letters. .

    Here are some rough guestimates. BORE ......................................................................................... 4.0 STROKE .................................................................................... 3.5 FLAT TOP PISTON VALVE RELIEF SIZE .................................. 2.0 GASKET BORE .......................................................................... 4.1 COMPRESSED GASKET THICKNESS ...................................... 0.041 COMBUSTION CHAMBER SIZE ............................................. 58.0 DECK HEIGHT ........................................................................... 0.015 STATIC COMPRESSION .......................................................... 11.02 + IRON HEADS + 015" DECK HEIGHT (.057" SQUISH CLEARANCE) + 3.25 GEAR RATIO = PING LIKE A PACHINKO MACHINE If your pistons are at least 10 cc's they will be ok with the cam you have as it will have around 10.1 compression. Also, if the weight of the pistons is much different than the old ones, they need to rebalance it.

    "The worst part of this is that I got a call from the engine shop yesterday and the engine is ‘in balance’. This was really disappointing news and I am now trying to work out where to go next. Considering torque converter but have conflicting views on whether this can cause my balance issue. I will be talking to a transmission shop to see if they can service/balance it. at $500 to replace it I would like to be confident that it is the issue." Well you need to run a converter that has a higher stall than a stock one if you keep that cam if you want it to idle properly.

    well again, the point is that there is no point in assembling the engine if you have the small cc heads and the shop bought flat top pistons because it will ping. It is the shops responsibility to order correct pistons. If they order the wrong ones, they must get the right ones at no cost to you. That is how it is supposed to work and if it doesn't work that way at that shop I suggest you go to another one where it does work that way. If you told them you had big chamber heads and they ordered flat top pistons, and you then change to small chamber heads, that is a different story. Anyone that says the 4v heads won't produce decent low end torque are either over dramatizing the issue or are simply clueless. It is really that simple. I have had countless cleveland cars and built many 4v cleveland engines and they all ran well. Ford made about 2 1/2 bazillion 4v cleveland cars and not a single one ran "poorly" when floored from a dead stop, and that is a fact, although the boss 351's I have had definitely had less low end power than a regular 4v cleveland. It is illogical for one to think Ford would produce 2 1/2 bazillion cars that ran like crap when they were floored. Unfortunately, way too many people want to seem like an expert but very few are, and it sounds like the "experts" you are referring to forgot to mention that your engine will likely ping with flat top pistons and aussie 302 cleveland heads.

    Well can't you simply rewire her or are you missing that connector?

    Here's 2 us sites that are dedicated solely to Clevelands and Clevor's. This is a new site someone from the old network54 cleveland site started. Sadly, the netwrok54.com site is no longer accessible and all that info is lost. http://351c.net/board/index.php This site has a lot of info. http://pantera.infopop.cc/eve/forums

    You need to port them to get the most out of them if you want a high perf 351 engine because they are a bit lame in stock form which is why they were used on 302 engines. They are decent stock heads for a 302 but not so decent in stock form for any type of performance 351. There is a company in the us called powerheads.com that was and still seems to be porting and selling the aussie heads and they were getting big power from them but they are $2000.00 a pair and for that price or a bit more money, I would rather have some aluminum heads. Some of the best aluminum clevo heads are scott cook and chi. A few true clevo gurus are scott cook scott main, tim meyer and george pence and dan jones. Dan has done a lot of dyno testing comparing different parts back to back. Below is an intake comparison test he did. http://pantera.infopop.cc/eve/forums/a/tpc/f/5650045562/m/911102633

    No prob, we are simply trying to save you from a possible huge mistake. Around a bazillion aussies have put the aussie heads on 351 clevos with flat top pistons and lots of them had pinging issues. I also saw this issue on the aussie 351 Clevo forum i used to post on quite a bit. I know a lot about clevos and they are not like any other engine and hsve a few unique issues including a problem with the oiling system and the front cam bearing being installed to deep allowing a large portion of the oil hole to be ecposed. If you look at your ftont cam bearing you will see part of an ool hole just in front of it that the bearing does not vover. The derper the bearing is jnstalled, the more of this hole that is exposed which allows oil to jurl out of it like a volcano. The new melling oil oumpops have a problem with the byoass valve sticking and the factory t stat system sucjs and sometimes causes overheating issues ir it often has the wrong t stat in it ehich can also xause problems. As far as more compression increasing torque goes, yes this is true in general, but it is not quite true that smaller ports will increase torque as many people falsely believe. That is another very long anf involved subject. There is suvh a yhing as too little of something as well as too much of something. Bigger is not always best and smalleat is not always best. The right size is always best but obviously the secret is to know what the right size is for a particular app or at least know how to determine what the right size should be etc.

    it has very little to do with money because dished pistons cost the same as flat top pistons. if the shop ordered the wrong pistons for your heads, your compression will either be too high, in which case you will be back here asking how you can stop your engine from pinking, in which case we will tell you to lower the compression, or it will be less than is optimal which is a waste of taking the engine apart and defeats your purpose of getting more bottom end power. you can either get me the info i asked for, or take your chances, unless the shop has already calculated what your compression will be but they would have had to cc your heads to do that which they didn't do, and it should only cost all of around $10.00 just to check one chamber.

    if you change the rear gears, you could use the cam you have but it will still have some lope and won't have extremely high vacuum.

    well, it is FAR more complicated than that. if you want to build it correctly, i can help you but only if you get me the info i asked for. it seems pointless to me for someone to do all this work and not build the engine optimally but that is just me.

    i would have them zero deck the block then run cometic .035" thick head gaskets the same size as the bore.

    why do you think smaller heads will give you more power?
  14. barnett468

    1. You should to change the rear gear ratio then. 2. Get the part number. 3. Better get the part number from them or have them tell you the dome volume. Just tossing n pistons without knowing what compression they will provide is a sure way to have problems and a less than optimal performing engine. 4. xlnt, then you can run around 10.0 static compression. 5. if you get a 200 rpm stall converter it will be easier to roast the tires off the line, plus it will keep the engine from dropping a lot of rpm and lurching etc when the trans is engaged when a high perf cam is used. A numerically higher gear ratio will also help roast the tires.

    Probably half of the "lumpy" idle was caused by the out of balance issue because that is not a huge lumpy cam.
