The Cat 3208 (?) in the 33 FC has bit the dust and its time for a new engine.
As is an expensive operation and I'd like to see if any of the owners have any advice as to engine builders or have upgraded to newer or more powerfull engines in FC series.

Also, has any one changed/upgraded the transmission or added a 2 speed rear end or "brownie"? Any one installed a manuel trans?

Thanks
Jerry Thompson

Teddy Taylor changed from 210 hp to 250 hp in an XV. Major Job not satisfactory results! Then he added a two speed, very satisfactory results. See Harvy Lawrence's "Teddy and the Two Speed" in the March 2001 Family Motor Coaching magazine.

Seems you asked the same question I am asking - I have a '70 31'FC with a dead (ford 390 gasoline) engine.

Is there any advice you could pass along?

Thanks in advance

Jerry:
Although it isn't exactly what you asked, I have made some performance improvements on my existing 3208NA. It will easily run 80+mph in rolling terrain, runs 75mph all day long, climbs better, and accelerates better.
I've changed rear-end ratio from 5.29:1 to 4.63:1 ($1200)
Increased air intake to engine ($100)
turned the full-load point to 3000rpm ($38)
That's it! The best money IMO I've put into my coach, and I've put plenty into it.
I'd certainly look for the extra horsepower if you can get a 250hp to put in, but feel that the little Cat works fine if properly set up and it is much cheaper to install another 3208 as all of your mounts/accessories would otherwise need to change. I don't see any use in a two-speed differential (although I looked into it myself), mostly because you will gain lower gears not higher ones and the beast doesn't need lower gears. A taller ratio still gives you plenty of lower gears for climbing.
Feel free to email me if you have questions.
