Wondering about the cross member at rear of
stock six cyllinder point. When installing Chevy
Small block does this cross member need modification?
I have not had an opportunity to observe this.
The LS1 Gen 111 has a different bell housing and oil pan than
previous Small Blocks. Apparently they fit well in 60's, 70's
models. Not sure on A.D. truck. I am guessing mod's.
