Thanks for taking the time to look at my problems. Your response highlights a point of confusion. I originally measured duration at .050" cam (lifter) lift. Then I was told by my machinist that standard is to measure at .050" valve lift, so I went back and re-measured. My measured duration...

One other "simple" question. I measured our cam using a dial indicator, and took measurements at .050" valve lift. The 1969 Dodge factory manual lists OEM cam duration and valve timing, but does not define the reference frame. Anyone know for sure if the numbers in the manual are absolute, or...

Thanks, Kern Dog. I'm not afraid to put in the work to make it right. For instance, welding the distributor shaft to limit max mechanical advance is well within my capabilities. What I'm not so confident about is how to define what "right" is...

For those of you who saw my intro, I have some progress to report, which brings new challenges. I am helping to resurrect a long dormant '69 Charger which has a modified 318 built in the early eighties... I just did a valve job, and replaced head gaskets, valve seals, etc, and the engine is...

This scenario seems likely to me. Might even be that someone replaced the timing chain and got it off.

I like the idea of looking through the fuel pump hole. I will try that. All the valves passed the machinist inspection and will be re-used. He also said the 1970 vintage heads had virtually no wear evident. I needed some good news...

Not free... I guess a bargain is in the eye of the beholder. LOL

No broken rockers. ALL the pushrods were MIA...

I haven't seen the timing chain yet, I'll let you know... and I cleansed some carbon off the pistons, but it was suspiciously light... maybe that's another clue. I don't know what factory head gaskets look like, but I was curious if someone else did. Thanks for the input!

This should be fun... I provide the clues, and you pick your favorite explanation for what I found... See my intro post, "Wakening a 1969 Charger from a long slumber", and "Newbie 318 questions" if you want more background. Update on '69 Charger resurrection... Original "675" heads failed...

I really appreciate the perspective. I have a tendency to be a perfectionist with all things mechanical, but my brother and I chatted tonight, and we are leaning towards doing exactly this.

Thanks for taking the time to give me a very thorough answer. This all makes perfect sense to me now.

Thanks to all for your expertise. A couple more details to share with the left head off. First, the head gasket failure that was causing the "whoosh" sound every time cylinder #7 came up on compression... Easy to see why I initially diagnosed this as an exhaust gasket failure. No erosion in...

In response to WileERobby, here are pictures of the gasket surfaces of the head, our corroded intake, and a NOS intake. You can see that the head has two coolant ports, but the intake has only one...

I might have a clue on question 3. Looks like the original factory manifolds had manifold heat control valves that must have connected somehow to these passages...? Our car has headers, and so I presume the original manifold heat function was just disabled. Am I on the right track?

Hi all, I am a newbie trying to help my brother return a '69 Charger to the road for his son (see my intro). I have some basic 318 questions I was hoping to get some answers on... We are tearing into the original 318 to fix a leaky left head gasket (I hope that's all it is). The engine has...

Hi all, I am helping my brother and his son return a 1969 Dodge Charger to the road. My brother bought the car from one of my college buddies in about 1984, and for about 10 years, it was his daily driver. With a new family, he finally decided he needed something more practical, but we...
