So I melted a hole and my number eight cylinder of my GEN1 engine. So I am now building a new engine using an illuminator GEN3 block and my GEN1 top end. This is not a money is no object build. I’m just trying to build a solid reliable engine for autocross use. My Gen1 heads have been sent out to be cleaned up and have boss 302 Valve Springs installed.
This thread is a place to make comments if you see me doing something incredibly wrong. also hopefully it helps somebody down the road trying to do this themselves.
My first question or maybe comment involves an extra hole in the front of the GEN3 engine block. It looks to me like its purpose might be to allow some extra oil to splash in on the timing chains. Does anybody know for sure? Attached our pictures on the front of the GEN1 block and my old GEN1 block. Note the extra 33mm hole about 1 o’clock position from the crank.
