904/727 dimensions

Hey Wayfarer! You've given lots of good advice at thehemi.com so thanks again.
Wilcap says their adapter, which I have an older model of, is for a 904 among others. Which is why i started thinking 904.

What you say about the higher starter makes perfect sense since I can see on my block that someone previous had been monkeying around at the block ear by the starter...like he was trying to make a 904 fit.
Decision made, I'll stay with a 727.

Yeah I was concerned about behind the head clearance as I'm thinking I might like to put the heater hose there to neaten things up.

You just saved me a $2000 mistake!!! Thank you.
