I have an '88 motorhome with a 454 in it. The engine is carbureted (probably about the last of the carbureted engines, I guess).
I live on the East coast. When we head out West, the m/h starts losing power out around NM, because of altitude increases. In the mountains, it is very noticeable.
The problem isn't very serious. All it does is slow us down. We make it fine over the highest passes, albeit slowly.
A number of people install Banks performance packages. These will run somewhere around $3k to have put in. I just don't have that kind of money to spend on this problem.
I was thinking about maybe putting in standard exhaust headers, a mid range cam, and an improved breather setup. If all this can be done for $1500 or so, I would consider going this route.
Can a shop put a cam in without having to pull the engine? Same question for the headers.
who are some of the cam suppliers that would have a good one for this purpose?
