I'm looking at a Dynaflite chipmunk, the same as yours. ARF's are ok, but you can't beat a built up kit, the ability to reinforce if needed and to personalize it more.
So if the firewall is 4.5" with 3/4" of an inch on either side that you saying the width of the cowl is 4.5" + 1.5" -> 6".
I just measured my OS FT160 twin and it's 7.5", looks like the valve covers would have to stick out or I could just get a Saito 180 for it. Either way I like the look of the it and if I get one it definately would have to be in RCAF colors.

Do you have a line on the kit?
It has been out of production for several years, you are lucky to have found one. I do have a review of the plane from about 2001, the author put an OS 160 on it, and said it fit very well, you should have no problems. If I can find the article I can try to scan it and send to you.
Good luck on the kit, it is a good one, the rear fuse is a pain in the butt to do. If you want I am happy to provide any thoughts on the build
