You may have a "bad" ECM. I had similar issues and I replaced mine with a rebuilt ECM from Advance Auto and my readings were normal in TunerPro after that. In addition, my ESC and other sensors...

Re: I need help finding length of pushrods

When I built my 355 engine combo, I had to get slightly shorter pushrods. .050 or .100 can make all the difference when it comes to valve train geometry if you want it right / correct.

Re: Iroc Z 5.7 tpi cylinder head options??

Re: 305 Piston dish?

4 ~ 6cc ARE flat-top pistons. The valve cut-outs in the pistons are where the 4 ~ 6cc come into play. Depending on what brand piston you get, they will be in the 4 ~ 6cc range.

In this case 0.015, which is what I took off of it (steel shim head gasket from the factory). A lot of people use them for rebuilds and have had good luck with them.

Re: fan problem

This is true... if the connector / pigtail is not making a good connection and arcing intermittently, then this will cause tremendous heat build up and damage the relay.
