Does anyone know the actual dish volume of the stock replacement pistons currently available? (brand and part #) Also for the Badger pistons? I am trying to find a way to set my static compression ratio somewhere between 9.2 and 9.5 to one in a 401 using 54cc chambers. What I have been able to find in either cast or hypuertetic (spelling?) is either way to high or too low. Plus, most of the replacement pistons available don't list the actual dish volume. Specs are really tough to locate.
This engine will seldom see in excess of 5000 rpm's, will experience LOTS of cold starts in a cold climate, so that is why I am trying to avoid using forged pistons. I don't need their strength, I just need a descent compression ratio for a good torque engine.
Also, does anyone know of a head gasket that is closer to .040 compressed thickness rather than the stock .046?
From my browsing on this subject, it seems the manufacturers have their heads up their as* in producing what a lot of people are looking for. AMC by itself left behind a small market, but add the Jeep line to it and the market increased substantially. Seems to me that these two groups should get together and flood them with requests for what we need. Perhaps one might listen and produce.
Any way, I am done ranting now, or so I think. Of all the engines I have built over the last 25 years I do not believe I have encountered so many parts availability problems as I have encountered with this engine. I don't mind paying for what I want, just give us all something that so many seek!! Sorry for the last ranting.
