    Unfired Rebuild Compression?

    Gotcha - I'm just kinda learning as I go, best way to learn is by doing and all. Thanks for the info, and I won't go messing with things. Until they break, that is. Then it's fair game...

    Unfired Rebuild Compression?

    The bottom end is supposed to have a couple hours of run time on it already, What I've been worried about is whether he actually replaced them like he claims to have. But, when I do start it, I have no room to complain about bad rings, because I (kind of) trust the guy I got it from, so I...

    Unfired Rebuild Compression?

    Psh, I'm just so amazing that I can pull cord start a 14:1 compression V-12! :tard: Yeah, I know, I'm a little bit retarded today... It's been a long day, and I've been a little worried about the rings on this supposedly freshly rebuilt 360 block since I got it.. But hey, I AM insane, paranoid...

    Unfired Rebuild Compression?

    Had it sitting on the stand, and was curious - pulled out my compression gauge and a wrench and took a peek. Never heard of it being done, never done it before, figured hey, why not?

    Unfired Rebuild Compression?

    No overbore, stock pistons, heads milled enough to run well on a 318. Got about 40 psi on 1&2, and 45 on the rest. Just wondering if it's the unfired head gaskets...

    Unfired Rebuild Compression?

    What would be a "normal" reading for an unfired, stock-ish 360? I've got some numbers here that worry me just a bit.

    340 r.i.p.

    Shoot, I'm still a little confused how it got into the pan in the first place, much less past the screen...

    dipstick length

    Here's the stick out my 318, no accessories - looks like a 28" stick and a 9" tube. Basically about 10" inside the pan, this one says full about 8.5" from the pan entrance, and add about a half inch below that. Is agree that the easiest and probably most accurate would be to mark your own, though.

    dipstick length

    I'm wondering the same thing, actually. Possibly the same as a 318 pan? Will be watching this thread... EDIT: yup, same stick and tube as the 318 - looks like Summit has one, ebay probably has a bunch(can't check on a work computer...) I can measure mine when I get home, if someone else...

    Another 360 Build question thread...

    According to my calipers, the cam has a 1.250 center circle, and a max lobe height of 1.572, which works out to .483 at 1.5. Given that, I'm guessing that its the MP 284* hydraulic, p4120231, with .484/.484 lift, and .241/.241 duration at .050. So much for the p.o...

    Another 360 Build question thread...

    Measured the difference in face height between the '85 heads and the 915's, and the 915's are shorter by .10 - by my calculizing, that's 8cc(give or take). Assuming (yeah, I know, im a total retard for assuming, but I don't have a cc tool just yet.) that the 85's are a typical 71~cc, that brings...

    Another 360 Build question thread...

    So, I have here, a stock bottom end '85 360. I have a set of '71 360 J heads, milled to a visible, but unknown extent, or the '85 smog heads that came with the 360. Also, I have an LD4B intake with Eddy 600, or the '85 360 intake with the original Qjet. The rest of the engine will be...

    318 Retards Under Load?

    After pulling the heads back off the 'teen for the 360, I discovered an oddity. #1 cylinder has, quite obviously, not been fired since the heads went back on. Cylinder head is still clean, as is the plug. I will, of course, not be reusing the distributor cap or plug wires on the new 360...

    318 Retards Under Load?

    And when I say it retards, that's just because that's what it feels like - Kind of like dealing with a computer controlled car, and your fuel curve is messed up because the guy playing with the tune missed something. It's like hitting a rev limiter, except that the limiter is 4500 rpm higher or...

    318 Retards Under Load?

    Gas sat for a solid 24 hours before the jar got grabbed and dumped into a buddy's car, along with the gas pumped out from idling on the bowl =/... Looked and smelled pretty pure to me, and his car hasn't slapped him in the face yet, so I think we can rule out bad gas. Got about 1/3 of a gallon...

    318 Retards Under Load?

    Looks like the gas is alright, at least, there's no water separation. Vacuum is on the timed port, still (passenger side of an Eddy 1406). Once I find a T fitting, I'll throw in another fuel pressure gauge. Replaced the rubber line at the tank, it looked alright. The big reason I tore into...

    318 Retards Under Load?

    I'll check on that line when I get home, too. Floats, lines, any easy way to check fuel pump pressure without a gauge? Mine got jacked and taken to Japan...

    318 Retards Under Load?

    Ok, this started after I filled up at a little country store in the middle of nowhere, back in mid January. A week later, I started ripping apart the motor, and everything looked just fine. Upgraded the ignition box, did some other stuff, started her up today, and it still falls flat...
