Chevy 8.1 or Ford V10 ?
« on: July 29, 2017, 01:23:03 PM »
If you had a choice between engines which would you prefer? I guess this really goes out to someone you has had both.

Any disadvantages to either?

They both have their pluses and minuses but I would purchase based on floor plan and price.
Both engines will probably out live you.
A + for the Allison behind the 8.1
A - for the 8.1. Workhorse not building class A chassis any more. Slight service issue.
A + for the 2006 and up V10. 3 valve heads. more HP & torque.
A- for the V10 transmission having early down shifting issues. 5 Star tune fixes the issue.
Some owners suggest less fan noise with the slower turning 8.1?

All of the 8.1L Vortecs in the W series and UFO chassis had Allison Transmissions, earlier ones were 5 speed, later were 6 speed, and some where along the line transmission braking was introduced.  8.1L Vortecs in P series chassis (mid year 01-05) were mated with the 4 speed Chevy 4L80E or beefed up 4L85E transmission.  I have an 8.1 with 4L80E in my 2002 Safari Trek, and while gear ratios and spacing are not ideal, it does an ok job.

I have had both and prefer the Ford. Just for the fact you can still get the chassis parts. I needed a couple AC parts for the 8.1 workhorse chassis and they were difficult to find and very expensive.

Chassis parts for the Workhhorse are still available and they still have a dealership/maintenance listing of repair facilities.  I had my engine AC compressor replaced in an RV park by a roadside tech who told me it was a common compressor and he got it at his nearby auto parts store. Expensive?  Almost all parts for an RV are expensive.  Example  Auto mechanic price at local shop = $70 hr.  RV mechanic price at local shop = $120 hr. For that reason I have anything that is remotely automotive repaired by the auto shop (and the guy has done some minor RV stuff for me also).  At one time I thought I was having a starter problem on my 8.1 but it turned out to be something else. But I bought a new starter for it anyway and carry it along in case it gives  out on the road - price = $45.  So while I know nothing about the Ford, I would recommend the Chevy 8.1.  I will confess that due to my own negligence I had to replace the Allison tranny when I ran it out of fluid.  The torque converter had a minor leak and I did not take the time on the road to have it fixed.  Lesson learned - any drops of tranny fluid - get it fixed NOW.   lol

No reason I can think of to choose one engine vs the other - both are solid performers. Other reasons, e.g. transmission gears (more is better) and chassis parts availability, may have some modest significance, but not a big deal compared to "house" factors. The suitability of the floor plan for your needs and the overall condition is by far the greater importance.

In an RV, a 5 or 6 speed transmission is notably superior in performance to any 4-speed, so if your other criteria have been met, choose the better transmission gearing. I'm a fan of the big Allison trannies (3000 & 4000 series), but see little difference between the Allison 1000MH used with the gas engines and the Ford 5R100 & 6R100 trannies. The seem equal in reliability and performance.

The 8.1 and even the old 7.4 Chevy has more guts than any ford powered coach that I have driven. The V10 is an improvement, but I'd still not own one of them. Looks like I'll NEVER own a coach built after the 8.1 was discontinued. When I had a 250 hp 7.4 in my Challenger, a few of my buddies had 460 powered coachs, we made a run to a Pinks all out race several years ago. Not one of them could run with me on the open road. I had to slow down so they could keep up. All of them but one has switched over to a GM powered coach, and one of them has switched again to a diesel pusher as he went to a 30 ft race trailer. I love the 8.1 and the Allison trans but not so fond of the W22 chassis, at least the one I have. My old P32 chassis coachs handled much better than this one in the wind. Not so sure I'd want to pull a race trailer with this coach, at least not very far. The old 7.4 and the GM tranny coachs also got better fuel economy, but they were in a lighter chassis, and sat closer to the ground.

Spoken like a true Chevy aficionado!  ;)    A Ford guy will likely pop up soon.

No reason for a Ford guy to counter Charlie. He speaks with a forked tongue. Chevy never made a 250 HP 454 P32 MH chassis. If he gets his numbers right, then a conversion might pursue.

I think he just fat fingered the numbers: Chevy-230hp/Gm-290hp

OK it may have been a 230 hp 454, even more pathetic when a nasty 460 couldn't even begin to run with it. ;D ;D ;D   I'd NEVER even consider a MH ford powered.
The guy that bought that Challenger was driving a newer Mustang, and asked me what all had been done to the 454. There is just no comparison. Be honest with yourself, for once.
