Thanks for the great write-up, 451Mopar. Very helpful.
The engine pieces were considered carefully. And it was built by a reputable shop. So, hopefully I just need to dial this thing in some more. I have paperwork on the thing I just need to dig to find it so I can give you more details.
In...
This does make some sense. I'm still learning a lot about carbs to be honest. I've done most of my work on Fuel Injection, MAF stuff. I had the Carburetor Shop do a rebuild on the carb I just put on. It runs quite a bit differently now, and not entirely all for the better. So, I'm sure I need to...
Yeah, it is a rattling sound. I usually back off the throttle when I hear it. I have had it go away with octane boosters. Engine is VERY fun then. I'm just trying to find the right booster for now. I built the engine to be able to run some E85 which is why it is 10 to 1 compression. Then I got a...
I put a fresher carb on today. It handles less advance better. I've got it down to less than 5 degrees now. I hear detonation when I am about 3/4 to 7/8 of the way to full throttle now. Much less than before I think. I will take some time and do a compression check one of these days when I feel...
Hmmm...Okay. I got the whole compcams kit. Overall, I kind of like the setup, but race gas blends will get spendy. What cam do you recommend? I went 268 because I like my car to idle. Plus, I have loads of torque right now. Or, should aluminum heads be in my future? The rest of the engine is...
Well, I moved across country and the rebuilder is 2000 miles away. And, it has been like 5 years. They may remember details if I call them I guess.
I've got 906 heads. Seems to me the compression ratio should have been around 10 or 10.5 to 1. When you say "detonation that you can hear clearly...
Changing the distributor curve is still an unknown science to me, but I will do some research. I've been fairly chill on the RPM's, and mostly just been driving a few miles at a time. I do stomp on it, but I don't go crazy with RPM's. Just changing them up. Thanks for the responses.
Also, as...
Low compression will cause detonation? I'm scared to check the compression now....Engine doesn't have 500 miles on it yet. How long before my rings are seated?
Like I said, it's fine unless I get into it.
I'm stuck at 92 octane where I live and my 440 is having a hard time with it. It seems to want more advance, but I'm constantly fighting detonation if I get into it (and where's the fun in not doing that).
Even at around 5 degrees btdc I'm getting detonation - and it still seems to want more...
I'm using 10w40 Valvoline with a bottle and a half of Comp Cams engine breakin at every change. I have a 7 quart pan.
With a high volume oil pump I am around 60-70 psi on average.
Any ideas why I have to pump the living **** out of my 440 any time I want to start it cold? Warm she fires right up, but if she sits for a day I have to pump it like 50 times while turning it over to get her to fire.
Changing timing doesn't really seem to help. I am still running points (long...
It's not even that, it's the time under the car redo-ing everything. blah. I want to drive the F***ing thing right now.
I'm not sure if I have a tolerance issue yet, either. I guess if I break another I will be closer to knowing...
And here it is... The guy at Pertronix told me I could leave the piece in the pan. Turns out, he was likely right. Oh well. Now the long task of putting it all back together.
The shaft stayed in the gear. I'm working on finding some help to push the car into my garage from the trailer. Then I will pull the pan. I will post an update. I hope to hill I find it in the pan after all this work....
Okay, I will leave it off for now. I just wanted to put it back on as I am working out of my trailer and will need to move it into the garage if I have to pull the pan. Guess I will be pushing it. Not that I planned on starting it do drive it in anyway. Just less to worry about.
It is a good...
Pulled the intake. Everything looks clean up top. I ran my finger in all oil puddles and didn't see any metal. The distributor gear moved freely up off the camshaft, too.
So can I put the top back together? I suppose I should pull the pan....yuck. I've got a new oil pump gasket on the way so...
