Researching for future choice...
I too, am interested in the James cowl. Reading on the site, I've found the following...
"Available for RV-6, RV-7, RV-8, RV-9 and the Mustang II in fuel injected or carbureted versions. Uses a prop extension. A shorter length, carbureted version of the RV-6, 7, & 9 is available for use without a prop extension."
The question I have is, does this mean that you can use the shorter version for carb setups, but MUST use the extended cowl for FI engines (don't know why, but I guess maybe room underneath for everything)?
One other question, what is the differential cost? I can see the price for the James cowl, but can't find anywhere on Van's site what I'd save by excluding their cowl from the finish kit (which I've yet to buy).
