I've got over 4,000 miles on my car now and other than the occasional issue with reverse mentioned above, mine works great with the 1" cylinder. (The reverse issue may just be my legs; I'm slightly height challenged at 5'-8" and have to move the seat up almost to the end of the travel for the adjustable mounts to comfortably work all three pedals effectively.)
It sounds like I need a different master - I guess I just need to figure out whether to go with a 7/8 or 1 inch. Compared to my 427 Corvette with a McLeod diaphragm clutch and especially to my late model Mustang GT (may have a dual-disc clutch) this clutch is already somewhat heavier than I expected. I assume this is the same clutch package Keith Craft sends out with most of his Kirkham motor packages so it shouldn't be anything unusual. A 1 inch master sounds like what I would like in terms of shorter travel but I'm not sure about in additional leg effort. So the 7/8 may be a good compromise. I need to make sure I haven't overcompensated for my heigth and entry/exit to the car by positioning the seat back too far. Although pretty tall, I typically sit closer to the dash and steering wheel than a lot of people who are shorter than I am.

Thanks

Can someone verify that the Tilton Model 74 series is being used for the clutch on ERAs? From memory that is what it looks like.
