I knew it was a Genesis block but when a Roush salesman denied it, while set up within 10 yards of the Genesis booth, a fist fight nearly broke out. The Roush guy had made several disparaging comments, including that they were junk, and the owner of Genesis went ballistic. It seems he does all the block machine work for Roush, from his comments pretty cheaply, and was pretty incensed.
I didn't want another fist fight to break out( because of me,LOL). Thankfully that's your baby now

I still think that engine looks to be an FE from how tight the headers are,compared to the ones in the other pic.. supposedly the same car, but the pipes are drasticly different. It is just as easy to use the wrong model # as it is to mis-indentify the engine,like the transaxle was. I thought those were the VC's that Roush used on their FEs...but again it's hard to see it. Since you are in England you may have first hand knowledge. I was just going on the pic.
Ron, you are correct regarding the second engine it is without a doubt a Windsor based engine the shot that shows the exhaust makes it easy to identify.. the first one isn't as clear or at as advantageous an angle.
