Pace ARROW

I own a 1989 Fleetwood Pace Arrow 35 foot Chevy P-30. I was just wondering if anyone else maybe has been experiencing my problem. My MH motor screams at 55mph. It is working way to hard to keep it at 55mph. I took it to a place that specializes in transmissions and had them check out the tranny. I thought maybe there was an issue. Had them change the fluid and filter also. They said it is working perfect. I have been reading forums and just wondered if this is normal? I did purchase this MH used and just wondered if the person changed the rearend. It just doesn't seem right that you would have to work the engine so hard to get to 55pmh. Thanks for any insite.

    I just think that the RPMs are to high. I don't think it has a lack of power. I have hauled a trailer with it and has no problem getting to 55 with it.The tach will tell. Thanks for the suggestion.

    NO I have not tried 65. Well..... Down hill once. I will have to look into a tach for it.The person I bought it from said he had no problem driving 70 with it,but I didn't know if he was being truthful or not.

    With only 3 speeds, and sitting right on top of the engine bay basically, you are probably just not used to it. Our old '82 southwind with the same motor and tranny would do 80 across the desert pulling a loaded trailer, no problem. I believe it had a 4.56 rear end. On a big block, your cruising RPM's at 55 shouldn't be over 2500. A tach is the next thing you add to that big block to know what she is really doing. Is it really struggling like it's low on power, or is it just that you think the RPM's are too high? Will it go faster than 55? Have you tried 65?

    It shifts into 3rd. Only in 2nd was my first thought also. I will have to look into a tach. I just thought it was geared low. The motorhome will get up from a dead stop as fast as my Dodge 1500.

    IT SHOULD NOT BE SCREAMING AT 55....I had a 86 Allegro /454 with 456 rear end...pretty much same as yours....so Iam familiar, sounds like you are in 2nd gear?....even with a 513 rear gear it wouldn't do that in 3rd....You need a tac to see what your RPMS are....that's the first thing..you cant analyze this problem without it....maybe you are hearing something else, manifold leaks, loud exhaust ,who knows? RPMS at 55 first. And if that 454 is struggling that hard , Id say something else may be wrong.....like timing, carb problems,etc. I would not trust it till its fixed.
