Looking to replace my damaged pulley.

Feedback is great. I dont have the Delorean manual so my page references are different. I have the Renault, Haynes, and Volvo manuals. I have all the information with the exception where they say...

Not looking to stir up controversy but I am looking for feedback from folks that have shimmed cylinders previously. I am finally back to the engine rebuild and stuck on the cylinder shimming. By my...

I finally got my valve seats cut and port flow measured for one cylinder. I did not get a true "A" to "B" comparison (before / after) so the information is just reference. I was really looking to...

On the cam rocker wear how many miles (or kilometers) were on car since the install and what kind of oil were you running? How aggressive was the cam profile? You wouldn't happen to have degreed it...

Hey Bruce, without empirical data it is all just a guess. I have no data on these heads with the exception of the pics and flow data posted - huge thanks again for that :wiggle:. I also have been...

Instead of re writing the info here is another link;

After the rough cut I have cleaned up the gouges etc and smoothed it all...

Martin Faulks is on this site now and again and has been an excellent resource of info. I am sure the guys on the Alpine site would also have...

Looks super clean. I forgot to mention a key point on the replating, I will not replate structural fasteners so I don't have to worry about hydrogen embrittlement. Your plater can bake them to...

It is $85 for just one part or all parts. For the various brackets and castings it make sense to just do it all. Besides most of the fasteners are M7 in varying lengths - not a common size. I can...

Pictures say 1000 words:

You can't get better info than that. It looks like a standard port and blend job which is what I would do as well. There are some details in the port lead in and valve seat angles that could...

I am getting ready to start to port the heads and want to know what people have done. Flow bench data would be primo. I have found a few differences of opinion on the port shape and lead in for...

As I looked at the wire brush job I kept seeing places I had missed do I decided to give media blasting a go. After setting it up I did not have any success. I used the same plastic media I used to...

I appreciate the comment on the shims, stacking may be done but I just see it as problematic. I have a proper machinists block (edge) but the scale was handy to take the pic. What I don't have is...

Dennis - Thanks for the response and of cource it sparks a few more questions:

"Other than what you are seeing is likely typical" This is really what I was looking for.

The concept of this...

I should have clarified the set up a bit more. I am measuring it without any shims to determine which shims are needed. It looks like the "white" shims but I am looking for feedback from people who...

I set up the block and liners to measure the gap for shimming.

From reading the various manuals I was expecting the liner to stand...

I tried several recommendations but did not have luck, acid and base washes but all they did was oxidize the aluminum worse. I found the best process was my old reliable wash with brakleen and a...

The pictures are very helpful. All my analysis says the bang for the buck is in exhaust porting and a high lift cam - see link in earlier post with a sensitivity analysis. The pics show the feature...

I don't know the specs on the DMC cam so I don't really know what you had to do to set it up. I have installed several cams in 4cylinders but they needed to be degreed out and needed a vernier...

I am looking for feedback from anyone that has put a performance cam in their engine. How did it work? Did you need to degree it in? Was there any special process for the install? I would...
