Mike, with all due respect, I will have to disagree with you here. I know plenty of machinists or fabricators who could make an adapter plate to mount that valve cover to that engine, and on this type of way out custom, it's not totally inconceivable, although probably unlikely. Now, if it were that valve cover on a Cosworth F1 engine, I would wholeheartedly agree.
Art, respects back at ya, I agree that machinists or fabricators can and do make adapter plates for these types of valve covers and if such an adapter was in evidence on John's engine then he could just say that his valve covers are mounted with an adapter plate.
I'm no stranger to fabricating on real cars, I have a '63 TR4 that has a 2.8ltr Ford V6 in it, which I have configured with a Ford electronic distributor connected to a GM HEI ignition module mounted to an external HEI coil and a heatsink I machined down from an electronics assembly. I never have to worry about having good spark on this car and can get inexpensive factory replacements to repair with (just not "Triumph" factory replacements). All of these car mods were done without hacking up the original Triumph parts, instead, new/fabricated parts were adapted to Triumph mounting points.
I suppose to make an exacting point that I could have said that the valve covers on John's engine for this build do not seem to match up with the head castings in a way that would have been done on a real engine and doesn't exhibit an adapter plate to resolve that issue but I failed to make those exacting points.
Anyone that cares to can make any comment they care to regarding any of my work that I have posted in this forum and/or any work I plan on posting in this forum, if comments are helpful/constructive I will most likely thank the poster...if not helpful/constructive, I will give those posters a response deserving of their post (most likely no response at all).
