Here is my upgrade from the original 200 ci head on my 1967 Mustang convertible.
My new head is a 250 head with the extra large Classic Inlines valves, a large log head and an Autolite 1101 with a 1.69 inch throat. It has been port polished and milled to yield 9.5 to 1 compression with a Reinz head gasket.
First off my new carb showed up with a broken acclerator pump arm.
Luckily, I was able to salvage the one of my original carb.
Good as 47 year old "new"
Here is a picture which shows what an 1101 gets you over an 1100. A huge difference in throat size:
Pulling the head:
Note that the head gasket is all but blown at the right side of #5.
The size of the large log is much bigger than the small log.
This will get a 2" or better straight pipe with resonator to maximize performance.
