Well the 302 is back in running order. This time everything worked out. Had some squeaking noises in the motor when it first started and for the first few minutes then it went away. Dad figured it was just a rocker that didn't have enough oil in it. I shimed my oil pump, so now I have 85# of oil pressure at 5,000, haven't gone higher than that yet, and about 60 at an idle. The thing just idles at 800 rpm, and it only has 8-9" of vacuum, with the smoothest lope in the world, and is way better than the comp. It definetly has more power than before. Oh ya, I've got oil pressure with 10w40 now, instead of having to use 20w50 to get over 50# at full pressure! Has about 70 crusing. Put about 80 miles on it it tonight. Let dad drive it and he thought that the roller cam was a waste of money and that it was to big. the specs are 230,[email protected], and .536 lift on both side. It's a hydro roller. My dad has since retracted his statement as it pulls harder right from an idle than the old xe268 comp that was in there. You can drop the clutch at about 1,200 and it won't die. Gave my buddy a ride, and from a 2-3mph rolling start floored it and shifted at 5,000 through the first 3 gears, and he said if we raced who do you think would win? He as a 500+ horse cleveland in a 82 ford shortbox, and I think he's worried. I'm not though, I think he'd kick my arse!  It goes to show that if you do all the work yourself and double check everything, and take your time it will work out! Oh ya, and the cam is supposed to be good to 6,500 rpm, can't wait to break it in more and see if it pulls that high, but I'm sure it will as the old cam did. It sets you back in the seat from a standstill unitl you let off! Only thing is it smokes blue when your on it hard and then when you let off, but maybe it needs some breakin yet? I used the same rings in the same cylinders, but they only had 600 miles on them and moly rings are supposed to take a while to seat. Plus there was still a crosshatch on the cylinders so they should seat, I think? What do you guys think. The plugs aren't black they are a perfect tan color.  ------------------

'...it smokes blue when your on it hard and then when you let off...'Just a possibility, but that could be an intake manifold gasket issue; high vacuum related. Congrats on getting it back on the road and poundin' some pavement  ------------------

Ya, when I put the intake on, it didn't bolt down the way I thought it should and made me a little nervous, but dad said to leave it. If the intake was sucking in oil though, wouldn't it cause it to not idle right? Right now it idles really good and smooth, lopey, but smooth. ------------------

One more question. Went out and looked at it today. Plugs look good, oil looks right where it was, maybe down just a shade, but the water was down a bunch. Well there was also water all over my inner fender, and underside, so it is blowing it out of the overflow. It never did that before. So if filled it up and tried it again and same thing, there is no overflow tank, just a hose, I'm only filling it to the bottom of the cores. when I got back I slowly opend the cap, and there was some foam in there, but as soon as I speed it up it went away and then when I let it idle it just had a little very small foam bubbles in it, so I don't think there's a gasket problem, do I just need an overflow tank or what? Anyone else have this problem? Also had my brother follow me today, and now it only smokes when I shift and it is just for a second, so I'm thinking that's normal, correct?------------------

Stang 72, It is a custom ground cam from MME racing in Washington D.C. It was custom ground to my specs, and I'd say they did very well, and would recommend them to anyone.------------------

Maybe you need a new radiator cap??? Maybe a bit higher pressure too???

Well, the oil burning problem is solved. I think it just had to break in a little again. It only smokes when I shift and just for a second, so I'm guessing that's o.k., but the water is pissing me off. I can drive it around down (below3,000rpm) and it is fine, but as soon as I put it to the floor it blows the water out. It has a new cap on it rated at 13 psi. The oil almost looks higher than before, but it could be just because the oil is hot and expands? The radiator was redone by a shop about a year ago and they took that little baffle thing out of the top, and now you can see the core clear as day, and it is a vertical flow. Do you guys think that it is possible that maybe it builds pressure and shoots up the core and forces it out the cap? Also when it idles or I rev it up to about 3,000 with the cap off there is no bubbles in the radiator, that means that the head gaskets are good right? I know that the heads are good and so is the block because it has had this problem ever since the radiator was redone, but it used to just barley do it, and after I tore it apart again, now this time it's worse. Or is it possible that it has to be under a load for the head gasket to leak?------------------

If it blows the water out when the water is under boiling temp you've got a blown head gasket.  SteveW

O.k. one more thing. Did a compression test, they were all at 160-165, very uniform. If it was a blown gasket, wouldn't the compression be down? Also there was a couple of drops of water when I loosened the drain plug, then oil, so maybe I have a different problem? Going to put a pressure tester on it later and check some more. Could the lower hose suck shut and cause excessive pressure to?I f I have to pull this thing apart again, I might just cry. I don't know how I can build motors for eveyone else and never have a problem, but when I do my own it doesn't work out. Maybe I should just sell the dam thing.  ------------------

Relax,I've been thru this before. When the engine is cool start the engine without the cap on. Rev it up and see if the water "boils" out. If this happens with cool or luke warm coolant it is a headgasket. The head gasket may not leak with compression, but can leak with the forces of combustion. Good luck, SteveW

Thanks for all the help guys. Ya I started it at about 120* and let it idle with the cap off and the water didn't rise or bubble, it just sat there. I then filled it up all the way to the top of the cap with it idling and it did the same thing. It just flowed crossways from the cap with no bubbles. When I rev it it goes down and comes splashing back up to the top, almost shooting. That is why I was wondering about the baffle thing. Would a blown headgasket cause a few drops of water to get in the oil? It seems as though the oil level has risen. I guess the big deal is I spent all the money converting it to roller, the heads have been milled, and the block has been decked, and I just see no reason why I should have problems? Plus I can't afford to fix it again, so I'm really angry with it I guess. When we first tried to start it I was using the old firing order, and the grinder decided to use the 351 order and didn't tell me. We had some flames and raw gas flying out of the carb and flames and smoke out the exhaust. Once we switched it around it fired right up. Do you suppose that we could have hurt something then?------------------

I was always told not to fill the radiator to the top to leave it about an 1" below where the cap seats.
I know you changed the cap, but might want to try another one. If there is water in your oil, then the head gasket is done.I know what your saying about not having the money to fix the problem,and using all of it to built the motor. Just take a break from it, come back after you've cooled off and see what happens. I always break stuff if I work on my car while I'm upset. ------------------

Ya scoop, I usually leave it a little low, but to check and make sure there is no air creating bubbles I have to fill it right to the cap. And it shows no bubbles, that's the crazy thing. Do you think that backfiring could have done it?------------------

btw my car does the same thing if I rev it with the cap off it will flow up. I leave my upper heater hose off while filling the radiator unit water coolant starts to flow out of it, to get the air out.
