Gil, I think your on to something. both of my front ribs "F-646" have been spliced to make up for the front slope and the middle rib doesn't come close to the firewall.
I cant rule out that the cowling has been pre-trimmed. But when i purchased this "project" there was no engine mount or engine so whomever never would have known where to cut the cowling.
At this point I think the only option is to order an exhaust and alternator, check for clearance problems and finish installing the cowling.
I have a fair idea that mine is going to be known as the "short cowl" RV6A and will be just a bit different from the rest.
Guess that's why they call them Experimental.
