[Fot] Towing cam (kinda OT)

[Brad Kahler]

We're in the process of having the 454 in our smaller 20' Motorhome 
rebuilt.  We plan on pulling a 31' race car trailer with this Motorhome 
and I've been trying to figure out what cam would provide the best 
overall performance for our application.  I would like one that has good 
low end torque up to about 3000 rpm and still be reasonable on fuel 
economy (of course!).  I've talked with several cam manufacturers and 
that seems to just muddy the waters even more.

The heads have 2.02 intake valves and 1.76 exhaust valves.  The exhaust 
manifold ports on the head small at 1.625" in size.  I've read and also 
been told that the smaller exhaust ports will help provide better low 
end torque so I'm planning on sticking with the heads that we have.  I'm 
considering using the Edelbrock Performer intake manifold but can't seem 
to find a good solution for a cam.

Anyone have any real world experience with a good RV towing cam for the 
454 with turbo 400 transmission?

Thanks!
