I don't know. My only guess could be that oil pressure has something do do with it. I didn't properly test the compression i.e. all spark plugs...
Well, I found the problem. A lifter not collapsed but instead "expanded". The exhaust valve on 6 was not quite closing all the way. It's...
Why would it affect all cylinders? If the leek is after the "divide" in the intake manifold shouldn't the leak only effect the cylinder(s)...
That doesn't sound fun. But this is idling like you would expect for a car running on 7 cylinders. There's a definite miss, but only on the one...
I don't have one. I could probably borrow one though. I never tested it when it was running well so I don't really have a baseline to compare my...
I can't really tell. That's why I didn't mention it at first. I thought it might not be relevant.
Anyone have any other thoughts, or is that about it? Verify valve spring pressure and cam lift, or else intake?
I'll try that tomorrow. I thought they were moving, but I'll look again. I had a cam lobe go flat on the 307 and it stopped moving almost entirely.
How do I check for that?
That could be it. I'll look at that tomorrow.
That's what I thought at first, but I swapped them between 6 and 8.
I watched the rockers moving with the cover off and the engine running.
Exactly there's no lifter clatter.
It's the opposite of that. It feels like it's missing at slow speeds, but feels almost normal when going faster.
I don't think any other cylinders are effected, It does feel like 7 of 8.
I'm trying to avoid it, but other then re-checking everything I already checked, what else is there?
I only noticed the poor running when I pulled off the Thruway from a consistent 85 MPH to a stop at the toll booth. I can feel the misfire when...
Hmm interesting thought. A leak in the runner. I'll re-check everything else tomorrow, (i.e. ignition and compression) and I'll pull the plug...
I built a SBC 350 for my car. I've got new bearings, rings, valves. 305 high output heads, Eddelbrock Performer intake, Eddelebrock carb,...
I've got a 350 motor that spun a rod bearing. So I bough a reground crank with matching bearings and a set of piston rings. I got the motor out...
Hmm. Maybe not such a great idea. Well I figured if someone else did it then I could do it. But I guess that's the difference between "could"...
Well, I read the topic you mentioned. Thanks. Unfortunately my block only has two offset mounting holes so it needs the 168 tooth flywheel. I...
Okay so here's the deal I've got a 1974 2 bolt 350 with a 1968 307 flex-plate. The 1968 starter doesnt bolt up to the new block because it's got...
I have a sun tachometer that doesn't work right, it reads both high and erratic. Could anyone who is familiar with these units point me in the...
I just went out and power braked it. No cross firing. Dave, I think your right, I have to find someone with an engine analyzer. This might just...
I did that today, all the rockers appear to move the same amount. There isn't any valve train noise I can hear, well at least not audible over...
I only used the 305 heads, but now the stock 307 heads are back on the motor. 2 degrees is what it says under the hood, in the Chilton manual,...
The motor used to run well, then I put in a 262/272 cam, 305 heads, Eddlebrock Performer intake and an Eddlebrock carb. It sounded awesome but...
The rotor is also new, I forgot to mention it. The wires are also newish. The dwell was set with a dwell meter. Could it crossfire, but only...
